[QUOTE="C5Performance, post: 137464, member: 2938"] Last post of the evening: Wes rides his motorcycle down a flat road and the timing curve I just shared seems to work just fine. The timing of his spark is correct for the rate of fuel burn in his engine. Things are looking good and Wes is on his way to Alaska. But....now he crosses the Mississippi River in Davenport Iowa. He climbs out of the river valley (takes about 5 miles) and his engine is struggling under this new LOAD. His engine has become more EFFICIENT under this load, and now his ignition is lighting the fuel too early! If Wes wants to finish the trip without blowing a hole in his engine, he must continue downshifting until his engine's efficiency is back to an acceptable level. ***he could also run higher octane fuel that burns slower, but on flat ground it would burn TOO slow*** So if the YELLOW timing line is correct for flat ground, how do you get your engine to follow the pink timing curve needed for higher LOADS? What if we could tell the ignition to change curves? This would not be possible using points or most aftermarket ignitions, but we can using the Power Arc based C5 ignition. All we need is a toggle/rotary/vacuum switch. Please ask questions at this point before we move on. [/QUOTE]
