What is the best setting on my vafc for a gsr spraying 55shot nitrous? I don't have much done with my 96gsr: intake, 55shot zex nitrous, and skunk2 coilovers. I was informed that it gonna rip $200 out of my pocket to tune the vafc on dyno with my nitrous and I don't have that loot to throw around. Also, my vafc makes my car boggle at the time vtec is supposed to kick in. It feels like I'm hitting my rev limiter. Is this the cause of the vafc not being tuned by the pros?

 

Make sure that your vafc is setup for your car. You will need at least an a/f gauge to make it any were near close. Tuning it to run with nitrous is stupid. Youre gonna have to change it everytime you squeeze then drive home. Your gonna drive around town wil super rich setting just incase you decide to squeeze? Thats no good. Your zex kit should meter the fuel just fine for a 55 shot. Dont even bother with it.

 

each setting is different for every car. with only an intake the VAFC definitely wasn't a worthwile buy.

for your VTEC problem, check the settings. make sure it's set to 06 in and 06 out, 4 cly with the diagnoal-up throttle. and check the VTEC point settings.
