'08 dodge blowing ECM's- HELP!!!

I have an '08 Dodge Cummins 2500 with 6.7. it also has a mini maxx chip in it. I just had a new (rebuilt)transmission put in it, and a BRAND NEW ECM as well. Did'nt even get 5 miles before the check engine light came on. It is pulling the APP sensor codes of P2121, 2122, and now 2127. The 2127 pulled up when the truck was at the mechanics shop just idling. The old ECM was indeed bad, and we now suspect the new one as well (thank god under warranty!!!). Any thoughts as to what is causing the ECM to blow??? Please, any help would be great!!! my mechanic is about to commit suicide on this truck!!! he has checked all wiring backwards and forwards, replaced the app sensor, etc....

Call H&S if you're still running the Mini Maxx. See what they say.

I've never seen a 6.7 ECM go bad, just because. A programmer has always been involved.
