So you want the virgin LT1Edit files?
So you want the virgin LT1Edit files?
If you have one.
Here they are:
From two 96 GS's....and the 94 Vette.
RENAMED FROM .LT1 to .BIN to be able to upload them! Just rename them back to .LT1
Cheers.
Too bad they encrypted the 96 files. You are out of luck, modifying manually the file.
The 94 is unencrypted and the two halves of the file are flipped.
Your only option is to upgrade 96 car with 94-95 PCM or lt1edit provide you with a tool to convert the file to raw bin.
Oh thats a shame!
The only way would to to de-socket the chips and read them back using some other device then?
If I purchased the JET product does that encrypt its files as well?
Cheers
Ive already tried running the 94 PCM in the 96, the knock sensor issue I solved, BUT the ABS/TCS and CCM talk on the same PIN9 and all sorts of errors came up!
It did start though....
Heres the two versions of TUNECONV for reference:
Change them from .BIN to .EXE
Found this on LS1TECH!?
May or may not be useful!?
Another, bigger converted from a JCL.
Sorry for the late response. I ve been busy hacking some 96 bins.
What I found is that 96-97 pcm have ALDL line which is active and can be used.
It has only some modes available.
Mode 01 msg 00 and msg 04
Mode 03
Mode 07
Mode 08
Mode 09
96-97 Mode 01 msg 00 is one byte longer than 94-95 PCM mode 01 msg00 and can easily be hacked to output the same data as 94 PCM.
I need some idle traffic logs on 94-95 and 96 corvettes to make a patch for retro fitting older PCM to 96 model.
The last bin is good and can be used, It is way too big than necessary since PCM has two memory chips. Eside is 64kb and tside is 128kb. Some trimming is required to make it usable.
Burning chip is not an option for you. The raw data on the chip is scrambled.
JEt might be an option. I found a tunercat file that can be modified manually and opens through a jet programm. I guess it can be burned too.
Regular jcl files are also encrypted.
so this is what the table looks like now?Originally Posted by kur4o

180 degrees AFter the cylinder fires? The injectors stop spraying at the bottom of the power stroke ??
Presumably it would be around the end of induction stroke, before compression starts and the airflow slows to a stop.
Another 40-50 crank degrees and we’re in spark territory.
Also does the adx now allow intermediate hex values rather than multiples of 16?

'95 Z28 M6 -Just the odd mod.
'80 350 A3 C3 Corvette - recent addition.
This is my work chart for gm 846 cam.
Red and blue is total open duration at exhaust and intake.
Yellow and green is the duration at 0.05 lift.
I chart the data to find the cam overlap and decide how to tune it.
I couldn`t get a complete cam data for stock b-body cam, and don`t have a reference point. Some experiments will be needed to figure what is the best approach to tune end of injection.
Chart is from stock b body. The red line 4 is injector open time.
As you can see it closes exactly at 270 degrees. As it is at b-body and corvette calibration.
I am sure the pcm counts $10 for 1 low resolution pulse, and the space between pulses is divided by it. And you get 90/16=5.625 degree resolution. I hope it is pretty acurate but will have to be verified.
Hi Kur4o
sorry to bring in a topic unrelated to the current discussion, but i wanted to bring this to your attention before i forgot about it.
if i remember correctly disabling the ccp via raising the temp enable out of range and setting the enable special cells to 0% will cause the pcm not to use the extra cells.
While looking through the $0D hack i came across this
maybe this could be ported to make a patch?Code:L48EC: FCB $07 ; FLAG WD, ; ; b7 1 = not used ; b6 1 = not used ; b5 1 = not used ; b4 1 = not used ; ; b3 1 = not used ; b2 1 = SEPARATE BLM PK/NEUT CELLS ; b1 1 = SEPARATE BLM A/C IDLE CELLS ; b0 1 = SEPARATE BLM IDLE CELLS
included the 0D hack below

Here is some cleaned up and revised version of all the stuff that is tested and working.
It adds some interesting mode4 control like real time control of VE, maf/sd modes and end of injection time.
You also get some enhanced aldl parameters.
How to install.
1.You need to flash your PCM with eehack 4.7 with insert patches tickbox marked.
2.Than read your bin.
3.Apply all patches from the folder.
4.Burn the bin with eehack4.7 IMPORTANT the insert patches box must be not ticked.
5.Save the patched bin for future improvements.
To make available extra controls use the supplied eehack_v92.exe, which must be run from the eehack installation folder.
Load the supplied definition file for improved datalog.
Instalation notes.
You need to choose between MAF primary and Speed Density primary patches and apply only one of them.
If you have indeterminate data warning when you apply the patches, first press remove patch box, than apply as usual.
Warnings.
If you are runnig Speed density mode and apply the patch, make sure that the skip unused region tickbox is unmarked when you burn the bin.
If the box is ticked the eehack will wipe the MAF table to FFs and switching to maf will not be possible.
I am working on a future version of eehack that will apply the patches automaticaly, but for now you need to follow installation notes exactly as written.
