V-AFC settings for 370's, 6:1 FMU, and 14 psi?
I'm trying to get my v-afc tuned right. I've got a Vortech SC at 13-14 psi, JE 9:1 pistons, 6:1 FMU, 370 injectors, AEM fuel everything, and a Skunk2 manifold on my JDM B18C. After I put the 370's in, my car idles bad and runs super rich (8:1 a/f or less). I've been trying to tune the v-afc. I have it now so when I'm floored in 3rd gear, it runs between 11:1 and 13:1 a/f from 2000 to 8600 rpm. The problem is that it still seems to run too rich in 1st and 2nd. How do you guys have yours tuned? What do you suggest? I think it goes from -30% at 1000 rpm, then decreasing to 0% at 9000 rpm at the WOT setting.

Re: V-AFC settings for 370's, 6:1 FMU, and 14 psi? (BlowOff)
well the 6:1 fmu makes the fuel pressure about 84 psi. before the vafc, i was running WAAAAYYY to rich. 8:1 a/f normally and 10.5:1 at the most. after awhile it wouldn't even run, it would blow black smoke, and the plugs were completely black.
