I have a 2005 Grand Cherokee 5.7L with a custom motor and U7317 preadtor. Im looking to swap to an NGC4 2007 Grand Cherokee 5.7L PCM. I have restored my original backup already on the original PCM, but will the predator have any issues with my custom tune not matching new CalID? Also will the predator try to update the CalId because it sees a mismatch between the vin and current CalId? Do you think I would run into any other issues with this setup?

Thanks for your help,
RJ

custom tune will have to be made from the new backup of the new pcm.

Okay. Mike would you be able to port my tune (joshi400_005b) to the new original backup (07stockPCM)? My tuner seems to have dropped off the grid. I have attached it in this post. Thanks so much.

its not that simple when swapping an entire pcm, NGC3 and 4 can have totally different tables and data.

My tuner was able to port the tune over but none of the PIDs are reading on the diablo when datalogging. I assume it’s deciding the protocol to record PIDs on based on the VIN? So it’s looking for PIDs for an 05? Is there a way to fix this? Also the Jeep feels like it’s only at 75% power at WOT. Everything else seems to be working fine
