ive been foolin around with the VAFC makin some adustments here and there. im looking at my dyno chart and i am realizing that the stock vtec dip is somewhat still there!! is there anything i can do to smooth it out more? i am really questioning the skills of the guy who dyno tuned my car. he left my ITR intake cam at 0 and ITR exhaust cam at -2.i thought he shouldve advanced the intake cam a little . he got me good power, my torque numbers are kinda low for my mods(110lbs with bolt-ons,itr cams,cam gears and vafc)....but ive seen better.


1)my low and high throttle is at 10%,50%. should i change that?

2)can u guys post ur fuel settings? i know each car is different and dyno tuning is the best way to do this, but i kinda want to tune it myself, especially now that im getting more track time. so i can see the difference in times.

3)the tuner only tuned my wide open correction. vtec is at 5500. -1 at 5500,and goes down to -5 at 8000rpms. does anyone have any numbers at low rpms?


thanks for the help guys...and gals if there are some

 

Best way to tune it yourself is with a air fuel meter. You should be able to pick up a cheap one for around $50. Thats a start.

 

i have an autometer one. guess i should get it working again so i can monitor it. anyone have any #'s i can work with?

 

???!!

 

yeah id like to know too, i've been playing with it and just keeping it on the rich/stoich line on my a/f meter. i dunno what thats doing for my performance but thats what i heard was good for the car

 

vtec crossover: 5900
fuel: +16%
+2% fuel 5000,5500,6000,6500
throttle: 10%

that was my set up. worked great for me!

 

ohh yeah, my vtec was a little high, but trust me, i ran a better time at higher vtec crossover. about .126 better
