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

[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!

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...

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:
- 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

This is what the ALDL A276.ds for $EE says for the LT1

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

- DATA BYTE 1
.
.
- DATA BYTE 38
- CHECKSUM

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. http://delcohacking.net/forums/viewtopic.php?f=28&t=220&p=14029#p2489 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 is converting one of these files to a format acceptable to TurnerPro RT. Robert

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.

Yes 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!

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

abbrevations defined.pdf

[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!

[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...
