I just got EFIlive flashscan (used EFIlive scan tool only before), I currently have a custom predator tune installed in my car. When I did a read of my PCM with the flashscan, it worked fine, but I had to reconnect the predator and reload my custom tune. Basically, it looked like reading my PCM "hosed" the tune I was running until I reloaded it from the predator. Anyone else using these two tools? I'm wondering if the predator tuning is sensitive to any "other" tuning tools....I just wondered if anyone else had experience with this problem...thanks in advance.
