71 Duster Timing

Also research your distributor position, and realize that with electronics, you are not actually talking about "advance" but rather, "retard." That is because advancing electronics would be like time travel. The electronics generates a pulse, and you cannot have the spark happen before the pulse happens. The distributor/ trigger device sends a pulse to the electronics, and the spark has to be retarded to happen AFTER the trigger.

What I'm getting at is two things, both related. The distributor (if you use one) has to be adjusted so that the rotor is phased with the ignition timing, and the electronics has to be adjusted to deal with "wherever the trigger pulse" is happening. Just a wild guess, but (including "vacuum" advance) the rotor needs to physically be about halfway in the middle or say, halfway from about 15--50 so "around" 30-35 degrees. This is set "static" with the engine stopped on that mark, and the rotor physically pointing "centered" on the appropriate tower contact and of course the mech/ vac mechanism locked out.

Otherwise, whatever you type into the program is meaningless (CHECK IT WITH A LIGHT!!!) and the rotor may be pointing to the moon when the spark happens "at the sun" So to speak.
