Hello,
Veering off from the PCM Hammer v14 thread so we have something dedicated to this PCM.
Shortly I will post pics of the PCM and internals along with some logs. There are many of these that are corrupted or tuner locked and can't be written to even with GM software for repair.

Thread begins here:
viewtopic.php?f=42&t=6730&start=60#p101345
So we are at the point of we can upload the kernel to the PCM, but it crashes or cant talk back. So we need to identify the registers and hardware layout of the PCM. That means the watchdog addresses, usable RAM, an the VPW registers.....

E54 is the technical designation (Family name??) for the ECU used with the LB7 Duramax ...
That's all ... I just feel it should be included.
Has nothing to do with this test version.

Ah, didn't know that, I'll fix it. What do you guys think the thread title should be to aid in future search?

IMO it should have at least these key words, LB7 Duramax E54 ECU.

Fixed,
Here are two more .bin files, I have no idea if they are stock but the parameters section looks unmodified.

Are you saying PcmHammer created them bins??
Naw, you gotta be talking about the title ... I can't believe PcmHammer read the E54 yet.
