I was polishing my spare UIM and removed what I thought was the intercooler mounds bolt holes which are the little stubbys on top of the UIM. After which I found out that the Air Bypass Solenoid Valve attaches to this.

For some reason I think I really do not need this but have incorporated it into my FMIC.

What ill effects would I have if I removed it now? I guess it supplies bypass air into the primary intake manifold. I am running an APEXi BOV with a Greddy VSPL.

Thanks for any input.

If you want closed loop idle control it's needed.

 

Dam. DId not what to hear that. Now I have to mount it somewhere else!

Thanks,

Ian

 

sucka!

 

You will still be owned


L8ter dude!

 

my performance per dollar ratio is still better then yours!

 

Air Bypass Solenoid and closed loop idle. Huh? The air bypass solenoid is ONLY used during cold engine startup for a 17 second duration in conjunction with the BAC. After that it isn't used for anything.

Oh! Closed loop *idle*????? Really! Come on now.

 

So if I remove the Air Bypass Solenoid the BAC should go as well??

Thanks for the input.

Cheers,
Only because I want with the Bling 57pro's!!!

 

haha, oops! I read air bypass solenoid but thought BAC. Do'h! The BAC is what controls you idle speed.

No, keep the bac. It means you no harm and helps a lot. The Air bypass solenoid will never be missed by you. The same can be said for the AirSupplyValve on a series four. It's on the back of the throttle body. Remove it also unless you have power steering...then don't.

 

I have a S4 (1988)

I have powersteering but Cannot keep the Air Supply valve (ACV?) since I will be removing it to fit the T04B in.

Thanks for the input.

 

The Air Supply Valve is on the BACK side of the throttle body where the throttle cables and linkage reside. Since you have power steering keep it. The next time you take your throttle body off go look for it. It's a solenoid with a two socket connector on it.

The AirControlValve is a totally different animal. We're not talking about the same part.
