just got these today.

need to know what's goin on here? im guessing some sort of cold idle control




this valve can be controlled by cranking that **** on the hose, and it has a couple vacuum ports on it...do i need to give this a vacuum source or just leave it open and ignore it?

 

ive got the same itbs and been wonderin this myself

 

Its the idle adjustment. It cracks the butterflies open.

 

so should i run it manually?

also what do you guys do about the IACV? let it hang plugged in?

 

I wish i could afford a 929

 

It's the FITV.

 

 

**** you know better than anyone, stop ------- around with those and turbo it :1

 

take it to GD or shut it.

 

929RR ITBs are too small for a D15B7.

954RR's are a good match for a bone stock ZC, although they do start to drop power past 7K it's not by too much.

FYI, stock bore motorcycle ITBs on most of the stronger running Honduh engines... is a waste of time.
