Any final anti-ping advice I should try before giving up on my FRPP Procal tune?
The Procal tune makes my GT ping. I've tried the octane adjust settting, the crank sensor re-learn, and two different brands of the highest octane fuel I can get locally. On the advice of the Ford Racing folks, I started the car and let it idle for 15 minutes. Am I overlooking something that has any chance of reducing the ping? I really like the tune other than the pinging, but I just can't stand hearing it any more. It pings at anything more than half throttle, and when cruising on the highway, it pings lightly if I accellerate even gently. The knock sensors don't seem to detect the highway pinging, so I've got pinging going on quite a bit. Any suggestions? Does anyone here have direct experience with the pinging magically going away over time?
