We have a 2012 Jeep Grand Cherokee. One of the lifters went bad and we did a complete AFM bypass/overhaul. Replaced lifters and CAM shaft and used the diablosport intune i3 to turn off the AFM. Went for a test drive and the whole electrical system died. Replaced the battery and it was working again. Took the vehicle to the dealer for final check and they said PCM bad. They replaced PCM but could not turn off AFM. Our Diablosport intune i3 now says the vehicle is not supported. How do I get the intune i3 to recognize/support the new PCM the dealer installed?
Attached is the info file from our intune i3.

Re: Intune i3 says vehicle not supported
if you drove it to the dealership, the pcm was not bad 
The new pcm is reporting the same calibration, and I don't see a unsupported request in the info file, so its not clear exactly why its not working currently.
I'd suggest giving our team a call with the device in the truck so we can troubleshoot, 561-908-0040
Thanks

Re: Intune i3 says vehicle not supported
We replaced the alternator and the battery and it would not keep any charge. Had to stop 3 time driving 15 miles from house to dealer. The clock spring needed fixed so we asked them to look at it.
We will call during work hours.
