All the numbers are without meaning if the motor does NOT run well on the fuel
in your area. After the rough tune, test drive it and listen carefully for the sound
of detonation under load(find a hill). advance the spark until there is a slight "knock"
under load , then go back 1or 2 degrees. This is the real world setting that works for your
motor, in your local ,with your fuel. Remember that premium fuels will lose octane in the tank
if the car sets a lot. If you get a high speed detonation due to stale gas it is NOT good. This will
also contribute to heating up on the highway,watch the temp gage!
