    to the timing variation. The throttle angle I recorded was the one that's available as a parmeter on the measuring block pop-up screen. It was at 99.6% for all the data points on my graph, so rather than graph a straight line, I just omitted it. If there is a parameter that includes pedal input adjusted by some factor, it would be interesting so see as well.

    I am also going to graph an identical data set in a lower gear (2nd), when the engine seems to run just fine. It will be curious to see what the timing plot and retardation values like then. Thanks for your input.
