Topgunz - air to air upgrade

nic370 · 01-03-2017, 02:09 PM

Mine is all on now
Took a little longer as I have done a full install from stock as opposed to just swapping out water stuff

Spoken to my tunner late tonight he's send me a tune tomorrow so should get her running then

Can't wait now

Guys quick question... car threw a P0507 "Idle Air Control RPM Higher than expected." I am using the Turbosmart 25mm BOV and have it at the softest setting. Did some reading and got different points on adjustments. Should the BPV be slightly open at idle? If it isn't do I tighten it?

Your BPV needs to be open at idle. If anything you should loosen it. When i had the turbosmart on i had bought the lightest (blue) spring and even trimmed off a ring and a half to get the perfect amount of tension on the piston head of the valve. But, i did have the SI trim and 9psi pulley so it was pushing more air at idle. You should be able to trim down any of the springs to get the tension right.

OK....have it at the softest setting and it's still closed. How far open does it need to be? Do u think this is the reason I am.getting high Idle? We ran a smoker and couldn't find any vacuum leaks. Tried doing a Idle Learning via EcuTek but the tests failed and made my idle worse. Now idling at 1400-1500 RPM.

Weird thing is this just started happening. When I first cranked the car my idle was where it should be.....high 700s low 800s (RPM). Thinking it may be the Throttle Chambers but I'm not getting any codes for that.

You need a softer spring or cut that one down, it should be wide open at idle.

Thanks for clarification....I'm figuring by you and Topz response this has to something to do with my idle. I will try this out...hopefully it solves the issue.
