GM AcDelco ECU "E38 KeyFCKR"

by Flash/Tune

TESTING NEEDED!!!

Intro:

A long time ago, in a galaxy far, far away..
The E38 unit came into my hands after the EEPROM was damaged. The Seed/Key pair was irretrievably lost, the standard one did not fit... after about a couple of days (or rather nights) of trying to recover the key, this script was born.

Features:

• 2 bytes Seed Key brutforce tester (via J2534 device).
• Power control - L-Line (pin15). Use PowerBox or similar devce.

Script has 8 phases:

• 0 - Defaut Key (gmlan 0x92 algo)
• 1 - Key = Seed
• 2 - All algo keys in "gmlan" proto
• 3 - All algo keys in "class2" proto
• 4 - All algo keys in "others" proto
• 5 - All keys with same hi-lo byte (0101, 0202 ...)
• 6 - All keys with mirror hi-lo byte (0110, 0220 ...)
• 7 - Bruteforce all 65536 keys

Script have settings:

• runForward - Key from 0000 to FFFF, or backward
• swapByte - Swap high and low Key Byte (0001, 0002 ... or 0100, 0200 ...)

and some more. Look inside.

Curren progress saves in "history\%VIN%.last.ini" file.

• PS. Use Windows and Python 3.12 x32
• PPS.Code written by my monkey danсing on the keyboard.
