I attemped to do a full reflash on my truck then install a new tune, I get an error code stating that the serial number on the ECM is 0000000000 and to do a full reflash and EFI Live will assign a new serial.
We did this and it assigned the new serial and said it was completed successfully, after this truck still wouldnt start, we attempted putting in the dsp5 tunes that we pulled out of the truck and it still says the serial 000000000 error. What should I do next? Earlier in the day we used the "Program PCM with current calibrations and operating system" function a couple times, could this have created the problem? Please Help.
