2011 6.7 cummins 3500

Bought EFI live when it was released for this truck. Installed it deleted truck had been flawless for months. Today I was driving and my truck said see dealer now for exhaust. I figured the tune didn't read when I started the Tru k, shut it down restarted 4 times same issue. So I tried to reflash and reload the tow tune. Well it flashed the truck took about 10 minutes no problems but when it came time to load the tow tune in got error 0549 which is basically no communication. ....did my ecm jist get fried ? Any other possibilities ? Truck will not start or even crank but I have power to everything. Can't even get it to let me put the truck in neutral to have it towed -_- please help !

Did you delete tune it or just delete it without the proper tuning?

If you open up the EFILive Scan and tune program turn the key on, and go into OBD then click get info does it show the ECM in there?

The problem with this situation is that PPEI modifies the PCM file outside of what EFI supports. Therefor, PPEI is really the only source you should go to for troubleshooting. They may have more info on exactly how your truck is reacting.
