E92(A) ECU parameter mapping

[tonn0297]

Hello, thanks for all the help with the TCM compatibility issue, solution was to buy a newer TCM...
My question is i have a L83 with the E92A ECU, OS 12677878, and HPTuners is starting to remove any and all emission related parameters, so im trying to use EFI live and tunerPro to map the missing parameters out so i can put it in the user defined variables.
But trying to change parameters and save, then figure out where it changed is super jank and often it makes changes in the entire file.. Do any here have a map or know where i can find a file with some known parameters?

Kind regards

(Im allowed by law to remove emision equipment on my car from 1973, so thats not an issue)

UniversalPatcher has the DTC's layed out for that ecm and OS.

Thank you so much for that, I totaly forgot universal patcher! Sadly it's not the DTC's I'm most after, it's the enable / disable rear 02 sensor tests, and all the cat test + light off stuff..
BUT I'll compare the dtc list with hpt and see if there's any missing.
Just talking about this on hpt forum gets ones posts delete with no explanation or nothing.. Very "oh no we do not like this so you are not allowed" even tho we are paying customers...

Unfortunately Ghidra is really the only way with gen 4 gen 5 stuff.

Use an older HP version that has the tables you need. Modify the tables and export to bin to locate the addresses. Open up in ghidra and go to the locations. Note the instruction patterns and data structures. Then for any new OS you can search on instruction combos. That usually only returns a few results with one of them being the table you're after. That'll give you everything you need to create a xdf or define in efilive.

im using HPtuners currently, sadly i cant open my tune with a older version as it says its incompatible...

You need to read the file with the older version for it to be compatible!

yea, but the MPIV3 i have will not read to a VCM editor that is before like 4.10.. and the VCM version i can find was 4.6.xx so thats not an option

You've got a .bin of your ecm though, right?

yea, i have a HPT to bin, but sadly not the other way arround.. was hoping the "incompateble" was just a V number in the file

Another one bitten by HPs updates.

Having the bin is good. You ever used Ghidra or IDA?
