GM E38 E67 E40 Kernel/Bootloader Development Extravaganza

[In-Tech]

Taz, did you ever manage to get e98 read/write/cloning working?

I might need to clone my dads colorado ecu if 1 the injector drivers turned out to be rooted.

Unfortunately not, I went as far as decompiling GM/Holdens kernel to see what they did, seemed pretty straight forward to implement. Its just a matter of updating the erase/write/read routines and canbus registers realistically.

Well, that should only take a couple minutes

when cloning the E38, does it write the 2nd cpu for throttle as well?

Couple minutes... and a few dead modules

I did not add that in due to:
1) Requires decompiling and understanding how the original slave update kernel worked (If wanting to make a true custom one)
2) There is no recovery for the slave, fail mid flash means slave completely dies.

The factory GM kernel could be used... its a bit of a grey area legally though.

Ah makes sense. From memory HPT worked it out for the E40 and read it out of controllers but never did it for the E38.

Might be easier on the E40 possibly???
But Im not so concerned about the slave OS's, main importance is attacking the main flash and having very stable read/write routines.

I am interested in cloning a E38 multiple times for a project. I have used e38 so all 8 segments will need to be cloned, will this work?

What programmers does it support? Tactrix?
I can try VCM2. clone
pcmhammer failed with it

[Tazzi]

Both Tactrix and VCM2 do not support VPW (J1850) thus will not support PCMHammer.

For E38, E67, E40. These are all CAN Bus based thus Tactrix and VCM2 will work with them.
