I was downloading one of Shaun's JLT CAI tunes last night and the programmer froze at the very end. The screen said "Clearing DTC.....please wait". Waited 35 min then had to go to sleep. I turned the key off and when I checked this morning it was still frozen with that screen. I just pulled the plug. Didn't have time to start the car. What could happen? It seems the tune may have loaded but now I'm afraid to re-tune. I waiting to hear what Shaun recommends. Anybody have that happen?
