ive had my vafc installed for like a week she hesitates around 1500 just when i rev her up in nuetral (no shiftlinkage yet, cant drive) but if i reev it up fast past 1500 shell run perfect..... whats the deaal ?? is this the problem with the vafc hack?

edit: can it be fixed? + i dont have both 02 sensor hooked up, or my air/temp sensor

440cc w/ walboro 255 obd2

Mine does this too, because I have to set the sub-1000rpm fuel correction really rich to make my car idle right, so when I stomp on it it hesitates a bit... of course, I'm hoping I can fix this with tuning. Maybe someone who has had the VAFC hack dyno'ed/tuned properly can speak up and inform the rest of us whether fine-tuning it remedied this problem and the part-throttle hesitation/bucking that others (and myself) experience with the hack.

 

hey ive tried leaning it out and making it richer also tried changing the timing, and i still get this freeze at 1500rpms she just dont wanna go past 1500rpms but when WOT she goes past 1500rpms its really pissing me off
