Mechanical (Centrifugal) Advance Timing The extra fuel has a significant ant-knock benefit so timing doesn't need to be retarded as agressively. The timing of the ignition refers to the point between the compression and the power strokes at which the spark plug fires, creating the combustion that results in your horsepower, forcing the piston down into the cylinder. With the ECU plugged into the vehicle, ensure the ignition is off, and then proceed to plug the Ostrich into the ECU with the cable in the following orientation. So our ignition timing or ignition angle is referenced relative to that point in the engine cycle where the piston has reached top dead centre.

Note: Conventionally speaking, the red line on ribbon cables corresponds to Pin 1 on the connecting device. Launch typically 50-53 degrees adjusted for an optimum power at The engine revs out fine without load, however once on the trans brake at around 2k it starts sputtering and spitting out the throttle body, low rpm high load.
That is typically 15-35 degrees before TDC (top dead center) of the power stroke depending on the engine speed. Click to expand 15° initial 21° centrifugal ( msd no vac advance) all in by 2500 rpm.
