VAFC fuel settings
OK, here's my deal. I have a 97 integra with and LS/VTEC swap. B16 head and B18A block. I have the RevHard stage 2 turbo kit on it and my only fuel management is my Apex VAFC (stock ecu). There isn't any place I can dyno my car near where ilive for tuning. Does anyone know where i should set my fuel settings at wide and narrow throttle? I have RC 370cc injectors. My air/fuel ratio gauge bounces around too much to tune from that. If you can help, that'd be great. My head is stock except for a Skunk2 intake manifold and Skunk2 valve springs. My block has JE pistons and Eagle H-beam rods. If anyone has a similar setup and could tell me what they did, I'd be very pleased.

I run 370s and a 6:1 fmu, my fuel pressure is set at 36 psi w/o vac (28 with vac). I have all of my correction points 600 rpm apart starting at 1000. I start with -38% correction at 1000 and work up to -29% at about 3800 and keep it there the rest of the rpm band, this is for the narrow throttle. My wide throttle starts at -22% at 1000 and works up to -5% at about 3800 and stays the rest of the rpm band. My throttle postions are lo 10%, hi 65%. I'm running about 8.5-9 psi of boost and its running great. I will be wide band dynoing this set-up next month so I can fine tune it, but so far so good. Keep in mind that your setting will require less correction since you have smaller injectors, but this should give you an idea. You could probably get away without using the v-afc and just running lower fuel pressure and letting the ecu handle the rest. That was what I was going to do but I got a good deal on the 370s. Anyway, good luck.

This was from a post I replied to a while back. My settings have changed a little from the but not much. I should be wideband tuning soon.
