I THOUGHT for sure this was the theft setting i had read about but stumbled on something that fixed mine. I dunno why but changing my maf table to all zeros even though i am OLSD would kill the car immediately and it wouldnt restart..well start then die after 1 sec. Undo maf change and it would start. I did it 3 times in a row. Once it was running, i had rr set to update on the fly...set all maf table to zero and it didnt die. Weird. The other weird thing it did was this...scan and tune running.. connected...rr set to update realtime...went to clear codes and car died immediately....started back up but was strange doing that
