you need to drive the car around at low load situations, and use a wideband to get the car to run with an a/f ratio of ~ 14.3-15.0:1 at anything under 15%-20% throttle. (basicly any time your not in boost.)
what i did, was to watch the boost gauge, and use the one of the displays on the SAFC to display throttle position, and figure out how much throttle i had to give it before i would make boost. in my car, it was ~20-25% so i set the hi/lo throttle cutoff at 20% for the lo and 30% for the high, so that anything below 20% throttle was using the lo throttle map, and anything above 30% throttle was using the hi throttle map. (the SAFC interpolates between the set points.) then drive around and watch the wideband below 20% throttle, subtracting fuel till i saw at least 13.5:1 in the lo throttle map, and tuned on the dyno for the high throttle map shooting for ~11.5:1 -------------------- Former Team 5SFTE pro member ;)
