Heres the problem...I just got EFI a couple days ago and today took my stock ECM off and saved it. Opened the modified tune file and hit the red arrow. I had to do the ECM liscening and that, and kept going. Turned the truck off for 15sec then started it. Truck still has the stock ECM. So to make sure I re-downloaded the ECM and its still the stock one. So whats the problem? I've opened the modified file and tried to upload it 3 times now and no luck. Here is a display picture of when I finish "uploading" the modified tune. Thanks guys.
