I set out today to install the tune I got from SoCal Diesel in our truck.

I started by just reading the PCM. The process hung after about a minute, so I waited for about 5 minutes before pressing the 'Stop' button on the screen.

When I attempted to redo the process, the ScanTune say's there is no calibration in the PCM.

The truck is dead.

Any suggestions on how to get it running again would be GREATLY appreciated.

Thanks,
Steve
