@Kur4o

Do you have any updated ida diss files?

[kur4o]

These are the most recent I have.
I am still trying to list all the different operating systems used on 96-97 bins.
I got some bins from the forum, but still far from complete list.

here is a list of 96-97 cal ids supported by tunercat vdf.

You must be popular, your inbox is full.

OP updated with V0.002

a bunch of auto trans related stuff has been labeled. It's massive!! Over 1mb!!

Hi there,

Good to see some works being done on 96 vehicles.

I have a 94 Vette Manual using EEHACK and a 1996 Grandsport Manual using LT1Edit(Hmmm), Having been tuning them both for some time now and have raced both.

I have tried looking at definitions 002 and the latest vsn 3.2 but Tunerpro sais I dont have a late enough version even though I have downloaded the latest one? works ok with 001.

I also have a question on the 12df2 End Of Injection Target Table. I am assuming when it says TDC it is meaning on the firing stroke not the induction stroke?

6 degrees would seem to be a bad value to still be injecting, for a sequential system, because the intake valve is already closed, does anyone have any thoughts on this?

It would seem at high duty cycles that the 94 or 96 LT's sequential injection is more or less constant anyway...

As a comparison a Lucas Mechanical Injection System on a Triumph TR6 or 2500 PI times the Injector to start 20-45 degrees ATDC on the induction stroke, a Cosworth DFV is 30 Degrees ATDC and a Cosworth BDG is 80 ATDC Degrees. These systems have a very fast total injection time that only spans 52 degrees crank(Triumph 6 cylinders) So all the fuel is well on its way in plenty of time before the intake valve closes.

I am curious to know if anyone has tried different values in the table which at low pulse widths would at least affect the idle!?


Cheers and happy 2018!

latest tunerpro version is 5.00.9130.00 ive uploaded a new version of eextra to the OP see if that works.

[jthompson122183]

ive added v0.003 to the OP, fixed some e-side locations per dzidav8 information from another thread.

[jthompson122183]

the End of injection table if from the TC definition

i dont have specifics related to this pcm, maybe @Kur4o will post what he has learned.


here is some info ive found about injector timing

Hi kur4o, can you export those databases to .i64 format? My IDA doesn't like the .idb files :( Thanks!

[EDIT]
Nevermind, I managed to open those :)

[kur4o]

I guess you are trying the 64 bit version of IDA. it uses the i64 files. The 32 bit uses idb.

On 96-97 bins eside main loop is almost identical wih 94-95 bins. Some stuff and extra tables are added though.
Tside is 2 bins in one file, first 32kb is same and the second 64kb is switched between two 32kb segments.
So you got part1-32kb+part2.1-32kb
and part1-32kb+part2.2-32kb.
I did not dig enough to find how the switching is handled, but part2.1 and 2.2 use shared resources as ram, tables and addressing from the first 32kb.

There are some different calibrations. Routines are not much different but the relative addressing is mismatch, so you have to match the tables` addresses between different OS.

If you have a 96-97 PCM on hand you can try datalog through ALDL line. It has some built in messages, or you can patch one with the data structure from 94-95 PCM.

[dzidaV8]

OK, I made some progress on this 96 dissassembly.
Reflash is done by OBD2 VPW protocol, ALDL line is mainly used for communication with Vette CCM, there are datalog messages, but very limited. Most of the data is accessed thorough OBD2 PIDs.
There's VPW 4X mode support, so the reflash should be quite fast. I'm beginning to think this will be a neat PCM to work with and great upgrade to $EE :) There are a LOT of PIDs to datalog and to choose from, so speedlog will be easy to do.
