"The BIG BOV thread" (Where all bov question threads get merged)

tuning isnt the issue.. the issue is the maf has already read the air, and is now fuelling for that air, but you let it out via bov, so now its rich..

but see what I'm saying is that if you dyno tune it can't they calculate the air to fuel ratio so then it won't make the engine run rich?

No. The rich condition doesn't happen under throttle.

The only way to make it work 100% is converting to MAP.

Ebay, here, NASIOC, I-club, Iwsti, Craigslist, Dealer.

It is easy, 2 bolts, 1 Clamp and a gasket or o-ring depending on which IC you have.


2 Bolts require 12mm socket IIRC, clamp is "Jesus style" so although a proper tool is sold to take them on and off, the good old plier method works. If you have no clamp a simple screw tighten hose will do.

If it were that easy, all the kids would be doing it
