A good way to approach the subject, as George implied, is to set the advance for some torque loss, say 1%. Then it would be "Min adv. for a 1% torque loss". That would probably be safe for all engines not octane-limited. Gary Casey ps: While building EFI systems for race cars I once - very reluctantly - agreed to put a manual adjusting pot for mixture on the dash. The driver said his Nissan (running about 85 inches MAP at 8500 rpm) kept running better and better as he turned the knob, until it blew up. We took the knob off. That's one way to learn from experience. Incidentally some say experience is the best teacher. I say it is the worst teacher - what good teacher would give you the test before the lesson?
