deleted my truck today and can't get the tuner to program. (I think) It doesn't seem to be doing anything when I plug it up to the truck and it isn't clearing the DTC codes. The autocal gives my error code $0502. I have tried calling PPEI and haven't gotten a response today. I need to get this truck back up and running. I tried watching a how to video on their website and it refers to a *.bbx file to load on the auto cal. I didn't get those from them when I purchased. I got 5 files 4 files with *.coz and one called A_Flash.ctz any help you can give me would be appreciated! I would be glad to give someone my phone number to try and call and help if you think you can.
