A lot of people who buy VAFC don't know what they're doing and end up using just as a way to change the VTEC point.

Properly used, the VAFC can be a tremendous tuning device.

It's relatively easy to install, but not all mechanics will install it.

Jack Harris of P1 Automotive (H1 champion '02) is a master of the VAFC. You might want to contact him directly for advice.

Do I need to tune the VAFC and the ECU up?[/quote:49546d0fef]

The Hondata are plug/play with the base programme.

To get the best out of it, however, you need to get a good tuner to spend time on the dyno. To get the best out of a Hondata, you should count on paying someone for as much as a couple of hours on the dyno.

If you're near Virginia, I can recommend Steve Sakai as an excellent Hondata tuner.

Steve thinks out of the box and can get the most out of whatever you give him to work with.

The Hondata does not need the VAFC, and if you're thinking about getting an ECU I'd stay away from the VAFC altogether, if I were you.

This is all just my opinion. You are going to find people who think the VAFC is God's gift to Honda...I'm just not on that bandwagon and prefer the invisible Hondata, even though it's more expensive.
