FItech timing control disaster

Here try reading this:

Ask Away! with Jeff Smith: Rotor Phasing and How it Relates to Aftermarket EFI Systems - OnAllCylinders

I know little (yet) about timing control. When I ran my Dart I did not use it. At the time, I simply did not want to take the time.

You may not have the rotor/ trigger "where you think." Remember, EFI which controls timing DOES NOT CONTROL timing ADVANCE. Read that gain.

It actually controls timing RETARD. That is, electronics cannot advance anything. Electronics can only DELAY or RETARD timing. This means THE TRIGGER POINT must be at or more than maximum timing, AKA 40-50 degrees BTC so that the system can electronically delay the spark "back" to the slow speed timing of (whatever) 15BTC or so, and then at higher RPM REDUCE the delay so that it is not retarded so much, that is, "advanced" closer to the trigger point.

With a locked rotor distributor, this places the rotor contact all out of whack, so that now it must be positioned/ repositioned so that it lines up with the cap, again because the electronics is pulling the spark "retarded" with no mechanical movement in the dist. mechanism
