ECU tunning about the IABs?

[lowproki]

Hi ther i read your forum and stickies and i was wondering how do i get the IABs to work on a P06. I just send it to get tune i read that it was possible to add it on to the P06 but i couldn't find a link as to how?

Or how are u guys running the IABs so that it works?

some one told me just run the vacum line with that little valve thats in between the vacum line to the trhottle body and that it will work. Is that true?

search an ye shall find but ya it'll work VIA vacuum

Yeah i have read lots of threads but people say they don't open all the way like they should thats why. this is what the tuner told me:

Tuner: the ecu can't be made to operate the iab's. what i do and have everyone else do is connect the iab diaphragm directly to an intake manifold port so they open and close according to manifold pressure instead of rpm. that way they still open at high throttle for the higher rpm power, and are closed at low throttle for the low end tq and better gas mileage while cruising. and i set the basemap up for that knowing what manifold pressure they open at.

Chip the P06, run Crome and use a map with IABs. You will also have to run a wire from the ecu to he IAB pigtail. Connect Black/Yellow wire on solenoid to switched ignition, the other to pin A17.

Hope this helps. By the way, I am running a P06.

You should be able to wire in IAB electrically just like the p28 by jumping two pins. And you need a "black box" that was on the intake manifold that has the actuator to operate the IAB. If not hooking up to vacuum should suffice but they will open early. As I recall an earlier member did an IAB test and it would open all the way at 1500 ish rpm or 2000 there is a video somewhere on here about it.

The first section on

USDM ODB1 B18C: ( ECU sends ground, IAB wired to +12v )

is what you need to do to modify a p06 or p28 to run iabs like stock. I lucked out and got a good deal on an auto p28 so all the components I needed were there already.
