Hesitation with VAFC hack?
Do you guys running the vafc hack get hesitation whenever you apply full throttle?
I get this hesitation when i try to apply full throttle (trying to get avcr to self learn duty cycle), but part throttle the car runs fine. My setup is H22 w/fmax kit @ 0.5 kg/cm2 (upgraded to t3/t4e), portflow PnP head, RC 440's, msd btm, vafc, avcr, and 0.057" headgasket.
I also got the FJO wideband and had to set the fuel setting to -50% at 1k rpm to get a/f ratio of 12.8-13.2. The higher rpm settings are at -28% but the a/f's are at 10.8 from 5.5k to 7.5k rpm. I'm going to lower the 6k-8k rpm to -32% give or take. Any insight would be greatly appreciated.

dont really get any hesitation with mine, neither does my other friend who runs it. Well, besides the split second it takes for the turbo to spool of course. Is this your first turbod car?
