Anyone know Holley Commander 950's? programming?
Well I finally made some real progress, l although I don't have it fully tuned, it seems more stable, and performs WAY better
1--Tore the controller apart, "douched" the grease/ dirt off the board, and reseated the prom in the socket several times
2--cycled all the adjustment pots through their range about 20 times
3--I had not liked how the pressure regulator acted, seemed touchy, and I think someone may have put a larger spring in an attempt to get more fuel. I found a smaller spring out of a compressor pressure switch, and the pressure now adjusts nice and smooth up, to, and past the 21 PSI spec.
4-- Checked the TPS with an ohmeter carefully, and could not find a problem. But I replaced it with the one off the Commander. I'm not sure it's the problem, I'll swap it back on tomorrow.
Overall runs MUCH better and seems more predictable and stable.
