new $EE tuning thing!

[steveo]

in other news, ABS/SIR is happening for the next release. at least scanning, but maybe testing/actuation if i can get the necessary information. eehack will do abs release for brake bleeding for sure, it's just too useful to pass up. i just need to test it on someone elses car since i deleted both modules on mine.

[fbody_Brian]

its just bitching because those are in the dashboard but not my hacked up mode5 'speed logging' definition. windows people dont see that output. i'll see if i can shut it up

oh, it's alright then. I usually only launch it from the console the first time I run a new build, then I use a shortcut. Not a biggie.

Same here, though I'd imagine it would be useful for a lot of people

[steveo]

im actually adding some of them to the msg5 speed logging thing in the next patch version. for some reason i had 'rpm variation' added which is totally unnecessary. if you haven't noticed, to get speed logging in the new version, just disable the 'main' message and enable the 'speed logging' message. the analyzer and dashboard should cooperate, but in graphing you need to choose the correct message. i might leave it like that.

Steve I would beta that on my z if you'd like.. let me know.

[fbody_Brian]

alright, somewhere along the way the transmission gear indicator got messed up. It says I'm in second while I'm cruising in any gear, actually it's displaying the "raw shift position byte". Not sure how that byte relates to current or selected gear.
The P/N indicator appears it may be backwards, both in the dashboard and the trans tab.
Also, the TPS in the Dash and Main tabs are correct, but the one for the trans is wrong, displaying 12% when I'm at 0 throttle.

I compile a quick mode 4 for eside. Fully working.
Structure and answer same as tside.
Also added some initial version of cylinder cut control needs testing.
It adds or substract from current selected value from both tables. [on and off idle]
You can Add or substract in increment of 1.

Usage
M4 1+2
M4 byte 1
$10 = 1 ALLOW CYL CUT M4
= 0 DISALLOW CYL CUT M4
$20 = 1 CYL CUT time retard
= 0 CYL CUT time advance


M4 9+10
M4 byte 9

$01 =enable m4 cyl cut [CYL 1]
$02 =enable m4 cyl cut [CYL 8]
$04 =enable m4 cyl cut [CYL 4]
$08 =enable m4 cyl cut [CYL 3]
$10 =enable m4 cyl cut [CYL 6]
$20 =enable m4 cyl cut [CYL 5]
$40 =enable m4 cyl cut [CYL 7]
$80 =enable m4 cyl cut [CYL 2]
M4 byte 10
CYL CUT add or remove delta

Limitations:

It can work on single or multiple selected cylinder but adder will be same across all and also it will retard or advance on all.
So for now I suggest one cylinder at a time untill I come up with something better.

examples

advance fuel on cyl 8 by 3 points
10 00 00 00 00 00 00 02 03 00 00
retard fuel on cyl 8 by 5 points
30 00 00 00 00 00 00 02 05 00 00

advance fuel on cyl 8 and 3 by 5 points
10 00 00 00 00 00 00 0A 05 00 00

retard fuel on all cyl by 4 points
30 00 00 00 00 00 00 ff 04 00 00

Warning mode 4 main patch must be applied before using the cyl cut patch or crash on cpu will happen.
So make sure both are applied.

I got some problems during flash.
I got very frequently the message can`t load mode 5 restard pcm.
One time when it happened when i tried to disconnect the PCM power the computer almost crashed with 100 % cpu and extremely slow response. It took me 15 minutes to close the eehack via taskmanager.
Xp sp3 with pure serial adapter, also happens on usb adapter.
Otherwise when it goes through the mode 5 loading it never gives a problem with flashing.

a short log for you, has trans, and press adpt enabled.
has a short run in PE mode.

i do see that now, and i know where i went wrong. i'll check it out.

that's a bin file

I got some problems during flash.

can you do a debug log with a virgin bin file and see what's going on? i remember we had this issue before when you were patching datastream stuff

I compile a quick mode 4 for eside. Fully working.

looks awesome i'll check it out!

Steve I would beta that on my z if you'd like.. let me know.

stay tuned. im having trouble finding the appropriate definition for the abs controller.

[fbody_Brian]

.

doh!!!

I fixed that. My bad.

[steveo]

alright here's another one

http://fbodytech.com/eehack-2/beta/

i added a hacky workaround for the injector pulsewidth graphing, a longer e-side mode-1 message, a proper implementation for ascii strings so the vin/siderail can read properly, and a ton of definition changes, including a full obd-ii set for vettes in message 5 (which doesn't work unless you choose not to patch).

people should re-flash their e-side to get the updated patch and the longer message (i didn't increment the patch version)

in other news i notice a few ios/safari users downloading eehack. im wondering if a native mac build is in order? shouldn't be hard to do.

I make a new patch for ind cyl fuel.
It is much simpler but it takes longer message.
All cylinders can be commanded simultaneously with sub or add.
It is not delta adder but is absolute value.
You need to upload 18 bytes of data via modified mode 0B message structure and response is same as mode 4.
First byte 0 is switch byte
1 to 8 bytes is new table for ind cyl fuel on idle 9-16 is new table for ind cyl fuel off idle
17 is reserved for future use.
With this mode you can upload custom tables upto 17 bytes long and the first byte will be switch byte of up to 8 different modes used one at a time only.
Single upload is enough and there is no need for keep alive message it will be on untill reset or clear M-0b message is sent.

M4 mode and M 0b can be operated simultaneously and dont interfere each other. So there is no special requerments.

Example command for mode 0b

01 80 80 80 80 80 80 80 80 7f 7f 7f 7f 7f 7f 7f 7f 00
[01]switch byte =00 disable new table load
=01 enable new table load
[80 80 80 80 80 80 80 80] new on idle table
[7f 7f 7f 7f 7f 7f 7f 7f] new off idle table
[00] reserved for future use

Both tables must have valid data uploaded, $80 is midpoint.


Requerments:
use new xdf for patch it has minor differences.
Memory clear is on separate patch and must be applied with M4 or M-0b patches.


I use completely stock bin with only aldl and m4 patches applied, so no timers skipped.
I will try to make debug to see what`s wrong.

[steveo]

might be a bit before i can test this patch, but it's looking really promising

In this same vein, would it be possible to create a walk through of installing your awesome tool on a Linux machine? I'm not new to tuning, but I am new to Linux. I did download Qt as recommended on your site, but I'm unsure how to proceed with building/compiling your Linux download, and installing the FTDI serial-usb converter I have, any help would be appreciated!

[steveo]

heya, good to have another linux user. what distribution are you using?

make sure you're using QT 5.6 or higher. earlier versions wont work. brian found that the baud rate wont set correctly.

then download the source from my website http://fbodytech.com/eehack-2/download-eehack/

unpack the zip somewhere, how about in your home directory? you can use the command unzip file_to_unzip.zip -d where_to_unzip

you have to open a command prompt and enter the directory where you've unpacked the source.

commands for moving around directories at the command prompt:
ls lists current directories (list)
cd enters directories (change directory)
pwd tells you where you are (print working directory)
cd .. will go up one directory
if the directory name has spaces in it, you need to use quotes, like: cd "this directory name"
if you type the first part of a file or directory and press 'tab' it'll probably fill the rest in for you

first thing you need to run is 'qmake'
then if that succeeds, 'make'
then probably 'sudo make install' would be a good idea

when fbody_brian wakes up he can help you out further. if you can't get 'er figured, maybe we can get together and write a build/install script or get a distribution package going for your distro.
