Based on my search of the archives and my amateurish understanding of how our engines work, the optimal (in terms of power, efficiency and detonation safety margin) ignition timing should be more advanced for LOP v ROP operations, less advanced for high power/high manifold pressure operations. Am I correct thinking that optimal ignition should be more advanced with high altitude operations (all else being equal)?
Because my home base is at 7k agl, I went with higher compression pistons/cylinders cutting slightly into the detonation margin ? not a concern at 7k agl, but could be an issue at sea level if the ignition is advanced too much. Should I be thinking about adjusting the ignition timing based on my operating altitude? Or may I simply rely on the MAP curve built into the electronic ignition I have since the high altitude operations is no different than a lower power operations?
