I keep thinking I have the BOV spring too loose or too tight. At the moment its on 3 turns but sounds like the piston is open way to long however I had it on 5 turns and it fluttered on lower rpm though, not sure if its meant to?

I got an alternate one but I lost it at some stage. Link to comment Share on other sites More sharing options...

Something to do with a air flow meter and something else Link to comment Share on other sites More sharing options...
Go Fast Bits Member 4 Member For: 15y 1m 28d Gender: Male Posted 01/03/10 03:50 AM Share Posted 01/03/10 03:50 AM Hey guys, Great to hear there's some positive feedback on the Stealth FX. As far as the adjustment goes, yeah, there's not a lot of room to play with in the factory location, but on the up-side at least it doesn't require expensive additional hard-pipe adaptors and it also makes it harder to spot! You'll find because of the nature of o-rings, the adjustment is harder to turn if the valve is cold, or if it hasn't been turned in a while. After the first turn, or if the engine bay is warm, it should be relatively easy to adjust.As far as the spring adjustment goes, the firmer it is the shorter the duration of the blow-off, and the more liklihood that you'll get a little low RPM fluttering. The softer the spring, the easier the valve vents and the longer is stays open for. This will reduce the liklihood of low RPM fluttering. Because there's no airflow meter, it doesn't matter to the ECU how soft or hard you have the spring, unlike a car with an AFM. However, generally speaking the best throttle response is had on the firmer side of the adjustment, but if you don't want to hear any flutter at low RPM go softer.
