Bov Querys

[Mangune]

Hey all Just dropping a line to ask a few things,

When you take the plumb back off the bov but stock Bov is still there, why does this cause Idling/Stalling problems an sometimes backfiring?

When installed a atmo bov i think, a HKS sequental (not new one) still had some idle issues.

Also say when your in parking rev the engine to bout 4K rpm it will drop down to 1K then up its self to 1.5K before dropping again?

Proberly stupid questions but any insight on this would be great.

Cheers

the factory bov is open at idle so un airflow metered air is coming in so ecu puts in not enough fuel or too much fuel . adjust the spring pressure on the hks one so it is closed . idle is also becaus of the same thing

Search. This gets asked 3 times a day.

You cant nicely run an atmo venting bov with the stock ecu.

The AFM reads X amount of air and the ECU fuels for that. Then when you lift off the accelerator, it dumps a part of that X amount of air.

BUT the ECU doesnt know that, and still fuels for the original X amount. Therefore its now overfueld. Thus your stalling/backfiring etc.

Just stick with the stock BOV with Stock ECU. Unless you get an AM ECU or piggyback to tune the overfuelling out, it will keep doing it.
