Thanks, Brian

The referance pulse is generated by a magnet inside the distribitor. The ecm uses that information to determine spark timing, and fuel delivery.

Thanks guys.
So is the Ref. Pulse and the Crank Pulse the same thing?
ie: Super_8Dm.xdf
*Enrich Accel Ref Pulses (Asynch)
*Crank Pulse Width Vs. Temp.

No, a reference pulse is just a reference signal on a wire from the ignition module. A crank pulse is a fuel pulse width of injector on time.
The asynch stuff is a number of injections things.
