PCM will not communicate or car start.

[Thedude]

2015 SRT Challenger. I was checking out new Trinity and had it write a backup. Went to restore and now will not communicate or start. Any suggestions.

So I put the unlocked PCM in and car started right up. I am not going to hook up the Trinity until I get original fixed. There must be a lock out of original when someon tries to access it. ? News to me if the case.

so you got one of our pcms but then tried to tune the stock pcm with the trinity before you installed the new pcm??

I did not try to tune it per say. I wanted to have original back up on my PC. I backed it up to Trinity. Transferred to PC? Plugged back into car. Would not communicate or start. Went back to PC and downloaded back to tool. Hooked up to car would not communicate nor start.

With unlocked PCM had a heck of time getting the calibration update to load. Took 3 times but did get it to go thru. Installed 93 tune with a few changes. Works great. Sending you guys my original PCM to get back online.
