I did an overlap because, well, I could with the VAFC-II because it had more settings. Also, I did not control VTEC engagement with the VAFC, I let the ECU do that and the VTEC engagement is not always in the same spot.

Really? I hadn't heard that. I thought it was always at 6K-ish (unless the coolant temp was too low). In what situations would it not be at the same spot? Have you actually observed this?

How much difference do u think an ap1 would get in 1/4 mile time w/ a smooth 7 hp/4 ft lbs gain over the powerband, gaining 16 to the wheels b/t 8-9,000 rpms? Does the higher end hp gain make a big difference? (only engine mod is an AEM V2 & I have a stage 3 clutchmaster's kit). Anyone run their 00-01 on a track before and after they changed their a/f ratio?

[ I know there isn't a specific answer that can be given to this question, just wondering what other people's results may have been ]

I hope this thread is not dead....but
I installed my V-AFC-II and it runs great...most of the time. Every now and then (1 out of every 5) time that I hit VTEC, it kind of hic-ups I guess is the best way to describe it. It is almost like something is slipping all they way up.
I plan on bringing it to a dyno soon, but until then, does someone know if this is hurting my car?!
Thanks!

It could be...

Did you do your own tuning without a wideband? If so, reset all corrections to zero until you can have an experienced tuner use a wideband to tune the VAFC.

You cannot use the settings for another car to tune yours...each car is different and requires a custom tune.

your best bet is to take the car t a dyno so youcan get the a/f ratio,or use a wideband on the street
