If you have a OEM ecm(cpu) the vss hooks to the trans and the ecm needs to see a signal from it. You may need to have your ecm reprogramed. Timing should be 8-10 BTC(advanced). Be sure to set the timing with the brown wire disconnected from the dizzy. Good luck and keep us posted

With the car at a higher rpm I lose the timing mark ,I think its going 'up' the scale,,, The timing is set at idle with the brown wire disconnected on the first mark above the center mark going up the scale ,is that to high!! Is going up the scale advanceing the timing?

Is it normal for the timinmg mark to go off the scale at higher rpm???
Not very high rpm just alittle higher than idle.
thanks
