What is the correct A/F curve for a H/C engine?
Before, on the stock program, without heads/cam/Z intake/LT headers I dyno'd with an A/F curve that was:
14.2 @ 2500 rpm, 13.8 @ 4000 rpm, 13.2 @ 4500 rpm, 13.0 @ 5000 rpm on to redline @ 6000 rpm.
With the new mods & programming the fuel curve is real fat and killing my HP, what should it be?
dyno with new engine:
11.8 @ 2.5 rpm, 12.0 @ 3000 rpm through 5000 rpm, then dives down to 11.0 between 5000 rpm and 6000 rpm and then bounces a tad to 11.7 @ redline 7000.

Mine runs best with a WOT A/F ratio as flat as possible at 13:1 :cheers:
Yes, i would say WOT A/F somewhere between 12.8 and 13.5 tops!Nitrovette :smash:
