Tried to write the pcm now car won't even try to crank

[2001 Pewter WS6]

I got the issue resolved with the licensing so I edited the factory tune. While it was in the process of writing to the vcm, it failed. I can't get it to reconnect. Also now when I try to start the car, it won't even try to turn over. My wife is going to kill me.... BTW this is on a 2008 TBSS. I disconnected the battery, I am hoping it clears out something and lets it start up at least

I assume your performing a write entire correct?

[2001 Pewter WS6]

no, I was trying to do a calibration only. I reconnected the battery and no go, it still will not start.

[Bill@HPTuners]

You understand you CANNOT perform a write calibration only on E67 pcm's such as yours correct and that it will fail every time? You'll usually get a 1C0000 error which is covered in our troubleshooting section of our help file.

I didn't know that but I do know... So what is the fix? Or do I need to have the dealer do something to it?

As per the help files > trouble shooting:

Error 1C0000.

This error often occurs in late model pcm's when performing a write calibration only. In these cases a write entire is necessary to reprogram the vehicle.

Why does such happen? What's different about newer PCMs vs older ones that require Write Entire? Just curious...

[Bill@HPTuners]

Its a GM bug on the E67 pcm's where it won't take a write calibration only. Them & ford pcm's are the only ones that won't take write calibration onlys.
