:hmm:Somewhere up in the high 50's with a HP/high volume fuel pump and adjustable regulator - start rich and work down the air/fuel ratio until it runs clean under load............adjustable injector timing, too.......... Your Fiero ??

Not my car
The last performance Northstar I am doing.
Well I am doing some PCM's both the 0411 and the OE Caddy PCM
I have maybe 20 parameters that I have to calibrate in the PCM's calibration. No need to play with an adjustable regulator.

You just want to keep the dwell time from going to far or wide open. I am thinking 80% is my max dwell time I want to go with.
