All you guys seem to be AP1 owners. Do you think those type gains are possible for AP2?

Easy install/tune? Are there preset settings or do people just play around with it? How would you know without dyno?

 

cant comment on ap2 guys, but i remember reading that 2000's and 2001's get more gains from the Vafc...do the 01's and 00's have a different air fuel ratio, than the 02,03?

 

^Yes they do. The best gains come from the 00-01's.

 

just got it installed! so easy dyno is on sat!!

 

how much does a dyno cost...

then how much to tune

 

doubt ap2 will get gains unless you have some good airflow boltons

i will get my vafc 2 tuned once i switch to my 00 ecu

 

If i went with this on my S would i see any decent gains, i like that i could adjust vtec a little lower, like 5500 and get my bolt ons working better together....but i dont want a toy that needs constant adjustment according to temp, and other factors. also is there any problems with the vafc damaging the engine in anyway?

 

From the Prelude forum the consensus was that the VAFC was only good for WOT tuning. All partial throttle tuning would be eliminated by the ECU over time and cause the car to run rich at WOT. Some said 3 days some said as little as 20 min. Can someone verify that the gains are more than temporary? I know some of you old Prelude members have moved over here and know what I'm talking about, even if I don't.
