Building a LT1 $EE ADS file from ALDL DS file?

[EagleMark]

Well I'm figurung this ADS file is built from origanal ALDL DS files. I have all them.

Once they are converted or built you have the equivilent for instance $42 is ALDL A033.ds converted is now A033.ads. Import to Tunerpro and you now have an ADX that can be custimized in TP and hand edited in NotePad or EditPad.

Most ds files have been converted and available on TP website but the one I need is not.

Does anyone know how to convert/build an ADS from the DS?

[JeepsAndGuns]

In the effort to lean...
What is a ALDL DS file? Is it a datastream defination file from like a scan tool? Did you just copy that file from a scan tool and then convert it to another file type to be used in tunerpro? I know ads is what the older versions (pre version 5) of tunerpro used, and version 5 converts them to adx. I have no idea what all these names or file extensions mean, so I have no idea what the diffrence is.

[Six_Shooter]

It's not overly difficult, just time consuming.

What you have to do is use the parameters that are stated in the DS file as the information you need to imput in to TP to create the ADS or ADX.

Look for my 160 Baud ADX tutorial on the Tuner Pro site, IIRC it's in the Scanner Pro forum. There are some differences when building an 8192 baud ADS/ADX, but most of the information is a straight across copy.

--==edit==--

here are a couple links:
160 Baud ADX tutorial (http://forum.tunerpro.net/viewtopic.php?t=1016)

A thread I started previous to the one above, that has some information about the bitmasks and such that can get a bit confusing:
Creating ADX files... (http://forum.tunerpro.net/viewtopic.php?t=771)

[EagleMark]

I looked over some 160 baud stuff I am familar with like the $42 which is from A033.ds and it made sense comparing it to an ads or adx file... I think I could do that... but there is no need they are all done...

But when I looked at the 8192 baud stuff and compared it to known files nothing made sense? Commands listed in ds were not correct in ads or adx... that is hard to follow... I figured if I could compare some stuff I could figure out why my EE.adx shows weird data...

I think this is going to be a long learning curve...

[Six_Shooter]

You have to make sure you are using the correct .DS file to compare to. Sometimes there are multiple .DS files listed for the same or similar applications.

[EagleMark]

Done that several times. The one for EE was written using A223.ds for a Y car. Commands do not match up to EE.adx but are close, extras were added? Couple were wrong? Like 0x57 should be 0x56 from the ALDL.ds

My car is A276.ds I started with the EE.ADX and re wrote all commands exactly from A276.ds and will try it out later.

EE.adx for LT1 can not work on Y car, F car and B car because they all use differant ds files. I verified this by getting a trail of DataMaster and there is a differant setting for each car... for instance CCM has to be silenced on Y car. B car does not have CCM tied into datastream but does have SDM or SIR and EBCM tied into serial data that would need to be silenced. The way I redid the commands were straight from the A276.ds and it looks like they are in there. For comparison my commands are twice as long as origanal EE.adx...

But then again I checked the $OD.adx stuff and it did not match up to ALDL data A219 or A217, I forget which, again extras were added... So even if I get them right I need to know more about how TP uses them... or what the extras are?

[EagleMark]

Just found the first EE LT1 adx file and another modified. In the commands they are nothing like what the aldl ds lists and nothing like the latest EE on TP website. So far I have about 15 hours into trying to learn how to do this from a ds file and just can't find the information.

Going to try them in my LT1 tomorrow and see if any work.

With Robert retired I just don't know if anyone will be able to figure these out.

Mark at TP is going to have to do a tutorial so we can write these. There's got to be a sceince to this. Even if I get data coming in on same it has a glitch where it jumps numbers for a second then back. Looked at the origanal EE first one written for SannerPro before it was incoperated to TunerPro and it has loads of silence commands the new one does not... with hex adress not even mentioned in the ALDL.ds... so how the heck do you figure it out?

[Six_Shooter]

It's probably an offset that is confusing you, remember hex always starts counting at 0 (zero).

[EagleMark]

I thought about that after reading your ADX write ups and the Understanding Hex at TunerPro. But some of the address are spot on, some were not even mentioned?

So it's like they used all ALDL.ds address but added a few.

Then as far as commands, replies and macros they don't add up from ALDL.ds to what's written in TP ADX... that is one thing I have to figure out and there is no documentation on is Commands.
1. Send Command
2. Listen for packet response
OK those 2 I have figured in the ALDL.ds
3. Listen for silence
4. Trigger
5. Macro Command
Those three I don't understand. But with these old/first written EE.adx files they have a bunch where the new one does not. I'll have to see if I can reverse engeener what's there

[EagleMark]

Here's the one I have been trying to get to work... To make things more confusing the listings for LT1 are below. Doesn't matter to much to compare them as they all have the same Mode 1 Message send... well some are 5 and leave out the trans? But most have six.

Been looking through a lot of ALDL.ds files and good know working TP ADX files. One thing I notice added to TP files in a Mode 1 Message send is extra code added? not just this EE.ADX it is in $OD.ADX and others?

ALDL.ds says: MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 0)
ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE NUMBER = $01
- MESSAGE NUMBER = $00
- CHECKSUM

TP Mode 1 Message 0 send says "0xF4 0x57 0x01 0x00 0xB4" So what is the "0xB4" for?

ALDL.ds MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 1)
ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE NUMBER = $01
- MESSAGE NUMBER = $01
- CHECKSUM


TP Mode 1 Message1 Send and it says "0xF4 0x57 0x01 0x01 0xB3" So what is the "0xB3" for?

Go to third and last Mode 1 Message 2 and it adds a "0xB2"

Also found in A223.ds Mode 1 Messages for transmit data there are Six. But only 3 are in the EE.adx... I'm wondering if this is why I only get some data? So if I add the other three I may get my data, but really don't know if I should add a 0xB1 on one 0xB0 on another, but then whaat to do for third? Guess if I knew why they were there I would know what to do?

[93V8S10]

0xB4 and 0xB3 are the checksum.

[historystamp]

ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE NUMBER = $01
- MESSAGE NUMBER = $00
- CHECKSUM

TP Mode 1 Message 0 send says "0xF4 0x57 0x01 0x00 0xB4" So what is the "0xB4" for?


The "0xB4" is the checksum.

Luke Skaff's senior engineering project was to build a scanner tool. He documents the commands in Appendix A Table 7. The request command is at the top of the table with the response below.

0xB4 and 0xB3 are the checksum.Ahhh from the guy who has made the coolest xdf and adx! :rockon:

Now since I am trying to add the other Mode 1 data fixed messages how does one calculate the checksum? I just saw a pattern of it going down... but it should be calculated from something?

I'd sure like to get the EE,adx working for the 94-95 LT1 engines. It connects and gets some data, some wrong data and some NO data...

Great link! :thumbsup: I've read his stuff before about the Northstar DIS.

Here's what I found in that Senior Project .pdf

For reference, refer to Appendix A for the list of commands each ECU mode is

activated by. The most basic command set will include in this order: a message ID byte,

message length byte, mode byte, and a checksum byte. The more complex commands

will have other data bytes transmitted after the mode byte and before the checksum byte.

The first command in the command set is the message ID byte which lets the ECU know

what category of command it is receiving. Since all the commands listed above and in

Appendix A are diagnostic commands they all have the same message ID byte of 0xF4.

The next command in the command set is the message length byte. The most basic

command set has a base message length byte of 0x56 and any other commands or data

transmitted increments the message length number per extra byte transmitted. The mode

byte is simply the desired ECU operation mode number. Other data bytes must be

transmitted in the more complex data modes which are: mode 2, mode 3, and mode 4.

The last byte to be transmitted is the checksum byte. The checksum byte is the one’s

complement of the sum of all bytes transmitted.

[93V8S10]

Looks like you've got the answer.

I didn't have to work with this on the masks I worked on, since working ADX files had been done.

Hope you can get it working.

[EagleMark]

That information pointed me in the right direction. But then got confusing. ECM Guy wrote:
Note:

1. The sum
check is the complement of the message. When the incoming message is added
it
will always have a LSB
of $FF

Well if I add 0xF4 0x57 0x01 0x00 I get a checksum of 0x4C? So that does not correspond to the 0xB4 So I added the 0xFF and got Ox4B? went down? did all this using a calculator. The looked at the Command entry/Edit box in Tunerpro and used the checksum and came out with the same thing... then tried the Checksum box with ones complement and got OxB3 but forgot to add the $FF from above and then got the correct Checksum that was there in the first place 0xB4.

So conclusion when building an ADX from ALDL is use info from ALDL.ds for that Mode 1 data message
ALDL.ds says: MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 0)
ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE NUMBER = $01
- MESSAGE NUMBER = $00
- CHECKSUM

TP Mode 1 Message 0 send says "0xF4 0x57 0x01 0x00" Click the Checksum box and choose 2's complement and you will get the 0XFF added to it plus incoming message for the correct Checksum of 0xB4 for that message. Copy it and add it to hex stream.
0xF4 0x57 0x01 0x00
and paste 0xB4 to get.
0xF4 0x57 0x01 0x00 0xB4

$B4 or 0XB4 is 180 in decimal. I still have not figured out exactly what is uses to get that number, but at this point TunerPro has another built in feature to serve this purpose! :rockon:

Then if you have the correct hex string 0xF4 0x57 0x01 0x00 0xB4 you can use the Checksum button to check, it should come back as 0x00 in Sum. 0x00 in 1's Compliment and 0xFF in 2's Complement.

Looks like you've got the answer.

I didn't have to work with this on the masks I worked on, since working ADX files had been done.

Hope you can get it working.Well there is an EE that works sortaa, but I checked all the LT1 forums and no one can seem to get it to work, some get this and soemget that and some get nothing... I get a little of each. So I set out to start from scratch. But had one that sorta works to compare to and lots of good known working ones to look at and reverse engineer... way to many hours into this already...

[EagleMark]

On to the next question. Seems I am trying to learn the hardest OBDI to start...

This is an what the aldl file A219.ds says for the $OD for transmitting data. Pretty easy, one command.

MODE 1 (TRANSMIT FIXED DATA STREAM)
ALDL REQUEST:

So I have six messages to transmit data, message five is from the transmission, original message 0, message 1 and message 2 are in the available EE.adx but only one is linked to... I'm thinking a macro for all six? How could I find out what each is for? One or two could be for inflatable restraints and one for electronic brakes I would not need...

[EagleMark]

Then on to next question which may have my answer to which transmit message is for what engine data, trans data and MALF flags and switches... don't have to read them all but look at the one in bold gives an idea what is in each.

But really how do you come up with the 0x20 or whatever needed for say Engine RPM?

Looks like Message 4 may not be needed, message five and six look to be OBDII code built in already in 1994! So maybe I only need the three?
Message 0
Message 1
Message 2

Wonder why they skipped message 3 in both?

I think your on the right track, I can't imagine that all of those different modes would be needed. In $0D there are other modes that are not used and even complete data streams that could be accessed, there is a lot of repetition.

My advise would be to look through the $EE hack for the useful data streams, and focus on those only. The same info that is in the ALDL file should be in the hack as well. Of course this depends upon having a well commented $EE hack.

[historystamp]

I'd sure like to get the EE,adx working for the 94-95 LT1 engines. It connects and gets some data, some wrong data and some NO data...

I assume you know ...

'94 & '95 were the transition years from OBDI and OBDII. Some people refer to it as OBD 1.5. This could be why you are seeing so many data streams.

Checksum is a value calculated from the data that is pasted onto the end of a data stream by the sender. The receiver recalculates the value to compare to the sent checksum. This way the receiver can tell if the data was sent correctly or was corrupted on the wire.

I read calculating the checksum as you sum up all the data. Discard any bits that flow out of the 8 bit value then flip the bit values: 0 to 1 & 1 to 0. ( Called one's compliment. )
0xF4 + 0x56 + 0x01 = 0x14B chopping = 0x4B complimenting = 0xB4
Same result as Luke Skaff's pdf page 21
I'm not sure were the idea of the 0xFF entered the picture. Seems to be a red herring.

What is a ALDL DS file?



ALDL -- Assembly Line Diagnostic Link
DS -- Data Stream
OBD -- On Board Diagnostics. Mandated in the US. OBD I, OBD II etc.

I've made a sorted pdf of this information, if there was somwhere to upload it.

The data stream files for GM OBDI cars '86 to '95 or so, can be found here:
ftp://diy-efi.org/pub/gmecm/ALDLstuff.zip

( this will download the file if you enter it into any web browser )

These file look like they came from GM. They define what data flows between the ECM and a scanner tool. EagleMark (http://www.gearhead-efi.com/Fuel-Injection/member.php?2-EagleMark) is converting one of these files to a format acceptable to TurnerPro RT.

Right here is open to any EFI documents!

My advise would be to look through the $EE hack for the useful data streams, and focus on those only. The same info that is in the ALDL file should be in the hack as well. Of course this depends upon having a well commented $EE hack.I have sorted them and discarded repeats and discarded the OBDII stuff as you suggested. Then when I looked in the only available EE.adx I could see where some were duplicated, probably causing some of the issues.

One duplicate is error codes, one is New MALF, one is MALF and one is stored MALF... so I am getting it down to one...

The only $EE hack I have is not much help when trying to compare to ds or adx although it is easy to follow the hack to XDF (mask) So if anyone knows where I can get a better commented one it may help!

I think the hack from ALDL.ds is the ads, but that is what I am trying to learn to do. If the ads was available for A239 A273 A274 A275 A276 then I would not have to learn how to. It seems they are ones never done on TP website.

I assume you know ...

'94 & '95 were the transition years from OBDI and OBDII. Some people refer to it as OBD 1.5. This could be why you are seeing so many data streams.

RobertYes I knew that, and looking through these ALDL files some have both OBDI and OBDII MALF flages, some don't. Figures I would try and learn on the hardest. With all the hours into this I can look back on 160 Baud which is simple and 8192 baud for earlier years then the 94-95 and understand it now!

I do appreciate your guys help! I am getting closer to understanding this and closer to getting one working!

Right here is open to any EFI documents!

Here is a pdf file with common abbreviations used in ALDL data streams.

[93V8S10]

But really how do you come up with the 0x20 or whatever needed for say Engine RPM?

Rpm is the 20th byte of data transmitted for Mode 1, Message 1.

20 GP6ERPMC COEFFICIENT OF VARIATION OF RPM
N = % * 10.24


Looks like Message 4 may not be needed, message five and six look to be OBDII code built in already in 1994! So maybe I only need the three?
Message 0
Message 1
Message 2

Wonder why they skipped message 3 in both?

Personally, I would make two adx files, one for message 0 and one for message 1.

[EagleMark]

That's a good idea... today I tried a Macro with both and did not work.

Thanks! I copied that post to it's own thread and will add it to the FAQ thread! :thumbsup:

[93V8S10]

That's a good idea... today I tried a Macro with both and did not work.

Only one message can be used at a time.

It is possible to have different macros for each message in the same adx, but you would need to change between macros and have different screens set-up for each message. Also, you would have to remember which screens were correct with the message being used. To much trouble in my opinion. This is why I did two different transmission adx files for $0D.

[EagleMark]

That sir, may be my issue!!!!

Now I have found a couple more problems.

One is "MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 2)" says "DATA BYTE 53" but at the end it says "BYTES 36-53 NOT USED" so should it be 53 or 35?

Next is from your $OD. ALDL says:
MODE 1 (TRANSMIT FIXED DATA STREAM)
ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE = $01
- MESSAGE = $00
- SUM CHECK
THE PCM WILL RESPOND WITH THE FOLLOWING MESSAGE:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $95
- MODE = $01
- DATA BYTE 1
.
.
- DATA BYTE 63
- SUM CHECK

In your adx it has Payload size 63, payload offset 3 which adds up to 66 but earlier in this thread you are supposed to add the 1 Data Byte from above which would be 67 and that is what yours has for Body Size.

When I look back to original EE.adx it never added the 1 in body size...

[EagleMark]

My Scantool will do all messages for engine, but I need to reconnect to do trans. So...

And!
Only one message can be used at a time.

So in the same adx you could have say three connections, but then change to list view for that connection...

So my question is can you rewrite the MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 0)?

Or could you rewrite MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 0) to be all engine data and bitmasks with list view on one adx.
and
Rewrite MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 1) to be all trans data and bitmasks?

Or could you rewrite MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 0) to include all data and bitmasks? That would be the nice way.

I'm not sure, it's been a while since I worked with this. I think you can do it either way, I'd try it both ways and see what happens.

I remember having to do some fiddling with that. Seems there is a difference between the TP4 ads and TP5 adx formats. When a ads is converted it doesn't add the 1 byte. Also, after I did the $0D files there was a discussion on TGO about this, seems most people were fixing the problem with a silence command or something, but Greg Moates thought adding the 1 byte was the best way. I'll look for that thread later today.

[93V8S10]

And! Since you an only have one message at a time, then would have to have a list view for that message. So in the same adx you could have say three connections, but then change to list view for that connection...

Exactly! But if your planing to share the adx with ever one, this may be a little much for the average noob.

Yes, all of this can be modified. All of the DS info is part of the calibration. You would rewrite this the same way you would rewrite any other part of the bin. Having a well commented hack would be a must.
What you would wind-up with, is a custom adx that only works with your bin.

[EagleMark]

Well since $EE has so much more info stock then $OD-$OE I think I would make one with only ALDL.ds info that would be usable for everyone. Then if everyone could use this we could work together and add/build another custom version.

With $EE silence commands are a step I have to learn. I know there is a CCM (ALDL A239.ds) at 0xFO on Corvette that caused an issue because it was tied into serial data line. Looking at mine I do not have CCM (ALDL A239.ds) but does have SDM or SIR and EBCM tied into serial data that would need to be silenced. I will have to find the address for them.

Adding one byte would be easy, adding a silence command... well what would you silence? Or would it be a pause?

[EagleMark]

WOW! Thanks to everyone who has helped so far in sharing their knowledge so I could understand this! :happy:

Because of this I figure out what I need to do and sort. In opening each Mode 1 message I found so many duplicates it was incredible! So I am no sorting them so I am left with only one of each. That way the information only has to go to one place in the ADX, the way it is now one entry needs to go to several places. I don't even know if that is possible...

Also deleting LOGGED MALF, deleting NEW MALF , deleting OBD1 HISTORY MALF, deleting OBDII NEW MALF, deleting OBDII HISTORY MALF... and just leaving MALF. That is how all other ADX files are for all other ECMs. Starting to look like a normal ALDL.ds file

I am doing this in the ALDL.ds file so I have all pertinent info left, then recaculating words so I come up with correct size file, then on to making it a usable adx file.

[93V8S10]

Here's the thread I was talking about: http://www.thirdgen.org/techboard/diy-prom/544340-tuner-pro-v5.html
Starts about 1/2 way on page 3 and continues on page 4.

Can't help you with silence commands, I would need to learn that too.

[93V8S10]

I am doing this in the ALDL.ds file so I have all pertinent info left, then recaculating words so I come up with correct size file, then on to making it a usable adx file.

Not sure if I understand correctly, but you realize that the message coming from the PCM will be the same size, with the adx you are just choosing what you will look at.
HTH

[EagleMark]

Yes it all came to me yesterday and I got one done. So I learned enough here and with cross/reverse engineering to build a adx from an ALDL.ds. It worked! Wrong just like the others...

Some things were set different then EE.adx available but I still got same results on a B car... sporadic data... I even found the address for CCM 0xF0 which my car does not have but Y and F cars do..., HVAC 0xEA, ABS or EBCM 0xF9 and SDMA or SIR 0xFA and disabled them in both mode 8 so I only get data fro 0xF4 from Connection Macro... still can not get solid data from the B car LT1... still the same as without... just can't figure out why... Years ago it was said to work on Y and F cars, but from reading all the LT1 forums no one can get it to work anymore... maybe it worked in TPV4?

I've got about 50 hours into this and for now it's a project that has to go on hold and catch up to life. Glad I learned this and all the help I got, but this PCM is a differant aniamal then we are used to playing with. Somehow, someday I will get it working. My scantool reads all the data and DataMaster reads all the data? Just not getting something right in TP...

[EagleMark]

Well another 20 hours of learning, testing and searching through wiring diagrams and ADLS files and guess what?

Ha! I got an $EE.adx file that works in a B car! I also know how to make it work in a Y car and F car!

Now I just need a 1994 1995 Corvette, 1994 1995 Camaro/Firebird with LT1 to test them too! As far as my Buick LT1 which would be the hardest It is done and works!

:jfj: :jfj::jfj::jfj::jfj::jfj::jfj::jfj::jfj::jfj::jfj:

[93V8S10]

Cool!

What did you have to do for it to work?

[EagleMark]

Extra Mode 8 to stop HVAC 0xEA

I had a Mode 8 for SIR and EBCM too but took them out and it still works.

Those are three things tied into serial data line from PCM, but so far looks like SIR and EBCM are not interferring. I know Corvette has a digital dash CCM? 0xF0 that is an issue on those.

Once I get this dialed in for my B car I will look for testers on Camaro, Corvette and I know a guy here with an Impala SS. From looks on wiring it may need a little tweak for each?

Been working on making it a professional looking ADX like the ones you made, which inspired me to redo the $42 stuff!

[EagleMark]

Here are the command codes for 8192 BAUD ECM/PCM (Most copied from Internet?)
Mode 0 – Clear All ALDL Modes
Mode 1 – Data Frames (There are many different message frames)
Mode 2 – Request 64 Bytes of Memory
Mode 3 – Request 6 Particular Bytes of Memory
Mode 4 – Control Mode
Mode 5 – Enter Download Mode (GM Development)
Mode 6 – Address Of Routine to Execute (GM Development)
Mode 7 – Broadcast Mode (GM Development)
Mode 8 – Disable Bus Chatter
Mode 9 – Enable Bus Chatter
Mode 10 – Clear Malfunction Error Codes

The most commonly used modes are Mode 1, 2, 4, 8, 9 and 10

Mode 1 is used for getting the operating parameters out of the ECM, in mode 1 there are also many different messages. Each message is a fixed length and contains different parameters such as RPM, coolant temp, vehicle speed, etc etc. Each message contains different items for different logging/diagnostic tasks. Some messages contain engine params, some transmission (auto only) and others for when GM connect tech-1 to calibrate the unit.
This is what you normally see "Mode 1 Message 0" in TunerPro. This is directly from ALDL.ds file

Mode 2 is used to upload the binary (the contents of the memcal EPROM) from the ECM to a PC.
This needs to be built into TunerPro, If you change out chip to EEPROM then you could upload tune from ALDL port like WinFlash does for LT1 PCM. It erases flash memory then uploads your new bin

Mode 4 is useful to fault find sensors. It allows you to substitute or slew sensor values. For instance, it is possible to override the coolant sensor and substitute it with a different value to see what effect it has. Or you can slew (or offset) the temperature by a few degrees.
I have no idea?

Mode 8 and 9 allows you to temporarily disable the ECM/PCM from attempting to communicate with devices on the bus. If you don’t issue a mode 9 (enable chatter) frame after a few seconds the ECM will resume its normal communications.
Mode 8 is what I needed to silence communications from my HVAC/EBCM unit at 0xEA

Mode 10 clears all the stored malfunction codes. If you are having problems and experience a CEL then a malfunction code will be stored in the ECMs RAM. It is possible to erase the codes by disconnecting the battery but this also clears other learning data so a mode 10 ALDL frame can be issued.
See how to do this with TunerPro:
http://www.gearhead-efi.com/Fuel-Injection/showthread.php?434-TunerPro-Mode-10-–-Clear-Malfunction-Error-Codes

8192 baud is a bi-directional. READ DATA ON PIN "M" OF ALDL CONNECTOR. Send commands in and get data out!

160 baud and is a uni-directional (read only) data link. READ DATA ON PIN "E" OF ALDL CONNECTOR
So Clear Codes will not work on 160 BAUD ECMs. It has no Commands, just 160 BAUD out.

[EagleMark]

OK, I got a math question and need an equation.

This is from ALDL.ds.
33 TRANDEGA NORMALIZED TRANSMISSION FLUID TEMPERATURE
DEG C = .75N - 40
DEG F = 1.35N - 40
And this is what I got for the way TunerPro want's it in conversion, I got this and it works right...
DEG C is X * 0.750000 + -40.000000
DEG F is X * 1.350000 + -40.000000

But I've been putting this one off because it gives me a headache... I think you put the 2 together as a 16 bit for one output, most are single 8 bit like above.
34 TCCDC TCC PWM SOLENOID DUTY CYCLE (MSB)
35 TCCDC+1 TCC PWM SOLENOID DUTY CYCLE (LSB)
%DC = (256MSB + LSB)/655.36
So how would one right this for TP conversion? Calling gregs78cam !!!! He has helped me with math before...

[EagleMark]

and another double 16 bit entry...

30 NORAWA RAW OUTPUT SPEED (MSB)
31 NORAWA+1 RAW OUTPUT SPEED (LSB)
RPM = N/8

[gregs78cam]

OK, I got a math question and need an equation.

OK, this one is easy, -40F and -40C are the same thing, which is the lowest point the computer can "see". and the 1.35 or .75 is the conversion factor for the digital to deg

This one and the next one are a little more complicated, and something I have not really jumped into but this is what I understand.

MSB = Most significant byte
LSB = Least significant byte

Think of it this way. to get more resolution? or sometimes just a bigger number than 256, you need to send the value out in two groups.

resolution with 8 bit 0.39%
resolution with 2 8 bit lines 0.000015%

[gregs78cam]

Sorry, I just needed to look at TP to see what you meant. see next post.

[EagleMark]

After some more coffee I will try and read that again...
:confused1:

To add to your info, from TunerPro Help:

Data Source Size - This specifies the number of bits (and bytes) that will be used to
calculate the displayed value. 8 bits equals 1 byte, and 16 bytes equals 2 bytes
(MSB, LSB), and 32 bits is 4 bytes (MMSB, MSB, LSB LLSB).
LSB First - Specifies the byte order
of the source data. If checked, the source data is treated as
least-significant-byte first. For instance, if the following byte sequence were
streamed, in this order to the port: [11, 28], if this parameter is checked, the
number that the stream represents is 2811. If this parameter is not checked, the
order converts to 1128.
Operation - In
this group of parameters, you define how the bitmask will be resolved into
either TRUE or FALSE. This resolution is done via bitwise operators. You can use
bitwise AND or bitwise XOR. Below is a description of these operations. You may
have to read it a couple of times and examine the examples closely.







Operation




Description





Example (binary)


Data
Operation
Operand
Result







Bitwise AND


If the bit in the corresponding position of the data and the
operand are both 1, then the corresponding bit position in the result will be 1.
Otherwise, the corresponding bit position in the result will be 0.



11101101
AND
11110000
11100000







Bitwise XOR


If the bit in the operand is 1, the corresponding bit position
in the result will be the opposite of the position's bit in the data. If the bit
in the operand is 0, the data's bit is unchanged.



11101101
XOR
11110000
00011101






But cut and paste is about all I can do when I wake up...

[gregs78cam]

OK so looking through the '7427 hac, it looks like you just set the value to display from packet 34 for the TCC PWM, and set it to 16 bit, and NOT LSB first. If you click "LSB First" it will read them 'backwards'. Then it will look at both 8 bit values and treat them as a 16 bit. I just had to look at TP to see what you were talking about. There are quite a few values that come through as 16 bit.

[EagleMark]

Yes I got that part.

I was looking through the 427 $OD and $OE trans stuff adx since $OD is supposed to be for 4L60E and a lot is simalar... but math does not add up right in equations, so I may not have a grasp on this yet. I'd like to learn how to do it by what ALDL.ds says then just copy from similar parameter. They say same thing as mine above for those values but the way you describe math equation is not same or it's probably my math skills and not having a full understanding of it yet... notice I said yet...

:thumbsup:

[gregs78cam]

I would think if the ADX is set to treat them as a 16 bit value, then the math becomes much simpler, just multiply or divide by conversion factor. But if you were to set them up as two ADX values, linked, then the math gets a little more complex.

[93V8S10]

Eaglemark, please don't use my stuff as an example of good math. My math skills suck! Most of the equations used came from other definitions of from the hack, these are most likely correct. But with the equations I had to come up with on my own, those are very hit and miss, especially with the 16 bit ones. You'll notice that several of the 16 bit xdf addresses just display hex.

[EagleMark]

Well then, we had better keep talking with Greg cuz he comes up with these equations pretty easy! Maybe he can add a "Math Needed" needed for TunerPro equations writeup when he has time.

I know I have another post like on previous page explaining how to get correct hex address from ALDL into TP coming...
