#3435, "RE: mega log view questions and dyno stuff" In response to In response to 1
Your duty cycle can spike up that high right when you start the dyno pull....I used to be worried about that too, but then I went for a run and had someone watch the duty cycle for me, and the spike occurs right before a shift, or when you slam on the gas....it has to do with the acceleration enrichment map, and the MS catching up to what your throttle is doing.
