But there are real problems with this approach. Which electronic ignition are you going to use? Are you going to manually adjust the E-ignition ? Or are you going to depend on someone's idea of a MP based advance curve? Need more information. Regards, George """ How much advantage at high altitude (20 inches MAP and lower) is there to advancing one of ignitions and not the other? How much advance is appropriate? What is the optimum advance compared to if both could advance? There are some that claim a 20% (maybe they said "up to 20%") BSFC improvement at higher altitudes. """
