Originally posted by XtremeRSOne thing of interest though, I put my adjustable timing light on the car, and had the advance set at 15 degrees in MS, then set my light to 15 degrees on the knob, and the light fires right on both of the cam TDC marks even..so looks like timing is damn near right on to what you set it to in the MS..

I got similar results measuring ignition event on my scope overlaid with the crank angle sensor output... I set the MS fixed to 29 degrees and it lined right up on a noticeable crank angle tooth.
