I have a U7131 Predator and I bought it brand new. I have had it for 2 years now and always ONLY programmed my truck. I go and plug it in and it tells me that my truck is not compatable with the software. It will read the last tune written but wont install a new tune which happens to be the stock tune because I need to take it in for service. I try to force it and it asks me for a code which I also do not have. Any idea why all of a sudden the Predator will "forget" my truck?

Yeah sounds like the dealership updated your ECU with the latest firmware. You could try and update your Predator with the latest firmware and see if your new cal id is included in it. Then try and reload a new tune.

I should have told you but I did have the truck tuned since the last time it was at the dealership. Then just one day my programmer "forgets"! Now I have a tune stuck in the computer and cant put it back to stock.
