a/f vs fp, chart from obd scanner?
this is from a 6psi sc'd h22a. i did three runs, discarded one, and came up with the following:
it's a 3rd gear pull from 2000-7000RPM. there was less than 1 minute between the two runs at the same fuel pressure, and about 30 minutes between the last 62.5 run and the first 67.5 run. based on this, what would you set the pressure at? i'm getting on the dyno w/wideband once i have something to tune out that nasty dip at the cam switchover, but until then i'm thinking 62.5 looks pretty good. the high pressures bother me (67.5 at full boost works out to +/-100psi on stock injectors.)
