IT HAS TO BE DYNO TUNED.

 

Each car has its specific settings, as no two engines are exactly alike...there has been some research that the VAFC will only work for a few days, then the ECU will compensate. You will need to reset the ECU every so often to see consistent gains. This is the main reason I have not forked out the $ yet for one. The S2000 uses a Manifold Air Pressure sensor instead of a Mass Airflow Sensor. This MAP sensor I believe is downstream from the VAFC, so any VAFC modifications to the air / fuel ratio will be compensated for by the ECU. You can still control the VTEC engagement point (some people lower it into the 5600RPM region). I would not want to lower it too much, because of driveability issues.

a TON of people have it. You should do some searches. You can lean it out a little bit but don't overdo it, because to run it safely you have to tune it. I would also suggest pulling your ECU fuse once a week so that the overcompensation by the ECU will be gone. Basically, your car's computer will try and undo what the VAFC is doing over time. I reset my computer once a week to give it a fresh restart. If you do this, just let the car idle for a few minutes afterwards to get used to the temperature/humidity outside.

i reset my car about once a month. my car doesnt fight it as bad as sone cars do i guess.

 

yea i'll probably have to get it tuned or something..but i'll try that resetting the ecu part and see..but do you guys think disconnecting the battery is the same thing or NO????

 

Well yes, it'll do the same thing, but then you have to open the hood, get your hands dirty/dusty from touching the battery wire, and then enter your cd player code. If you pull the fuse, you just get down on your knees and pull a little fuse out of a box under your steering wheel and put it back in 30 seconds later.

One is easy, one is harder.
