Where the BOV is binary in its operation, the bypass valve is near infinitely variable and already mapped by your existing ECU for the engine and chassis its installed in. Its a pretty kick ass piece of tech, I think.
Opinions are like, well you know. I run a lot of boost and a BOV. Its vented to atmosphere so its quite audible. What I find sometimes is that at partial throttle I'm blowing through the BOV. The BOV doesn't know I don't want it open, it just knows that there is enough pressure differential to crack it open. My point is that if I already had a pre-programmed variable control bypass valve, I'd be looking for ways to keep it not delete it.

well when you put it like thaaaat... i guess ill just use it and stop worrying about throwin codes without it haha thanks man
jfilipcic, thats the main forum i use and TimFreeh, i had posed that question in regard to secondary air bypassing at Club202, just waiting for some responses
. Maybe a wire in a o2 sim with a spdt relay that when the signal for secondary air happens it switches to an o2 thats lean cuz its in open air, ecu thinks its working, then sec air switches off relay switches back to actual o2 and closed loop.If i could only get my greasy paws on a proper c230k wiring diagram as my haynes manual doesnt cover it. or im crazy. any thoughts?
