My 05 lly won't let me read it with efi live and I think it's because I had a PPE standard in it for like 4 months. I switched it back to stock with the PPE and sold it. Now I can't read the ecm. I went to the dealer for a factory flash and they couldn't even flash it back to stock with their scan flash tool. I also have a compu start 6000 remote start installed, I also have a pioneer touchscreen radio/DVD player & hid headlights. I have tried everything that me and Steve from SS diesel tuning out of Phoenix can think of. I need a solution I need efi live and any help would be greatly appreciated. Thanks! -Paul
