Not yet. But someday it might. The grand prix is something I do want to work with.

Thanks for getting back to me.

Is there anything I can do to speed along the process? Or help out?

Attempting to resurrect this thread.

I've gone through the GitHub version updates etc. but couldn't find my answer.

Does anyone know if this is compatible with GM WII platform (Impala, Monte Carlo, Grandprix etc)?
They are also Class 2 Serial.

I'll just stick with 1x for now. Thanks for all the help. You've been amazing these last couple days. I appreciate your patience with me. I'm a still very new to this side of the community. But I've dredged through 100s of forum posts to make sure I'm as informed as I can be. I'm just happy to be ab...

No Luck. Turned 4x back on and it failed again. It could be my VCI. Its uses a Bosch MDI Emulator for the .dll That being said, when I first attempted the in-car read. It got to 100% in Highspeed mode. And failed during the CRC Verification. So thats one thing to keep in mind. Heres the failed debug...

Im going into attempt 4 or 5 at this point. Checking different different troubleshooting items off the list between each attempt to see if im over looking something. Should I just try cloning it to a known good .bin file from another car? EDIT: Tried Cloning it with a known good .bin file. No luck. ...

Neither. It looks to be working properly, but the PCM is refusing the request to upload the kernel to the address we are using on other PCMs. It likely would be able to work, if we can figure out what memory range that PCM needs. If you can provide the service number for our records, that will be u...

So I got a donor PCM from a 2003 Malibu that matches HW and Service Numbers from my Monte Carlo. Serv No. 12583827 HDW No. 12582720 I rigged up a bench harness as follows: OBD Side: Pin 16: +12v Pin 4/5: Ground Pin 2: Pin 58 on PCM (SAE1850+) PCM Side: Pin 19: 12v Ignition (Switched) Pin 20: 12v Con...

I was able to get the VIN and OSID during a basic Read. Unfortunately I didn't record them anywhere, I will do that this weekend.

Will keep you posted
