the IAB system is not a very complex one. i was thinking for the b18c1 owners running p28 ecu's, if you use an msd rpm switch to power the vacuum solenoid at 5700 to switch over to the short runners.
thoughts?

 

What would be the advantage of doing that? The whole reason for the duel stage intake runners is for better low end torque. Long intake runners=more low end torque...short runners=more high end torque. Honda engineers aren't stupid, there's a reason for everything...that's why they make the big bucks. The dual stage setup is nice , but if you're always going into vtec then I guess you can just change out the manifold for a single stage type to extract more high end power. I guess you can also just leave a dummy load on the solenoid wiring or somethin so the ecu doesn't throw an error code.

Just disabling/modifying the system would be a waste because of the manifold design.

sorry for being a dumbass...whats IAB?

 

Intake air bypass. It is basically the system that switches between the longer and shorter runners in the dual path GSR manifold.

 

the butterfly valve thing on the intake i am guessing? I dont know exactly what IAB stands for.

 

no wonder i didnt know...i used to have an EG...will be getting a GSR soon tho! (my sig)

 

I think you are misreading what steady is asking. He is asking if he can activate the IAB system at 5700 using an MSD RPM switch for the people who are running the P28 ECU vs the stock P72 ECU in a GS-R.
