Last week I downloaded the New Update (2.22?) and now HPTuners can not open my tune file, or successfully read it from my car. The car has been tuned exclusively with HPTuners and not any other software but it still asks me to repair checksum and then it fails. When I try to open file it fails.
This is very frustrating, and I need some assistance. I may be able to flash another tune on there but I have not tried. I WANT that tune that I have on there, and I have no way of accessing it either from the car or the computer after this new update.
