made my first attempt at datalogging with my Xcal2. I'm getting wierd, erratic readings for "spark advance," and don't know how to interpret them:
BTW, this is my "safe tune," which is suppose to have 14 degrees max timing at WOT. This is what the datalog was showing:
-In neutral/idling, "SPARK ADVANCE" was reading 20-30 degrees.
-WOT, it drops to 11-12 degrees, and slowly climbed with rpms.
-When I shifted gears, it momentarily jumped to 20 degrees, then returned back down to 11-12 degrees.
-When I let off the gas, it jumped up to 35 degrees, then slowly went down to 20 degrees.
Any idea what's going on with the readings? Its as if they're only accurate when the engine's under load?
