OK! 96 civic with a GSR swap. Trying to get the IAB(butterflies) to work the correct way.

Running a civic ex harness, and a chipped p28 running chrome.

Yes im aware that i wont have the IAB wire, or anything.

I was thinking that I would just wire them into the vtec noid, Did that, and realized that they were closing when vtec was hitting. SO! My question is, is there a way to wire in the IAB Noid to switch when vtec hits, so basically they will be closed until It hits vtec, then open at the same time vtec hits?

I had though that they were closed since they werent hooked up, but, Then I actually got my head out of my ***, and researched, found out that the default position is open. So, yeah.

Any help is awesome. Would just like to have them working, If its impossible, then ill just go back to running them open....

Thanks

 

Your running a chip p28, it is not able to read IAB's unless you jump a couple of things inside the ecu to be able to read it and have it rechip for the IAB's.

 

and you will have to put constant power to the ground wire coming from the IAB's and wire up the IAB wire to d17 or d20 than it should be in working order.

 

use the factory vacuum tank and soleniod and wire a rpm trigger to the soleniod..

or just buy a skunk manifold

 

Using the factory vacuum tank, and noid. You lost me at wiring a rpm trigger. Explain?

I considering having the Ecu worked on again, but I don't see the point in spending that money when there has to be a easier and simpler way. BUTTTT ill look into it.

 

Why?!? Just leave it open. We put my stock gsr on the dyno with and without the iab hooked up. It wasn't worth more the 5 ftlbs below 4k rpm. It was a stock p72 ecu and I'm confident tuning with it stuck open would have got it back. Not worth the trouble IMO.
