just finished the install and was wondering about the black iab canister. what do i do if i want to keep it attached to the manifold, or what do i do to eliminate it. (what do i do with the line from canister to: fuel pressure regulator, top nipple on mani, bottom nipple on mani.) right now i have the canister attached with the sensor and all 3 vacuum lines connected like they would be with the stock manifold. a problem is that the line connected to the small nipple on the top of the blox sucks air out of the canister and makes noise, so i think i am going to disconnect it and plug the nipple, but i dont think this is right. please give me any helpful answers. thanks.

some other problems you might wanna help with:

1. tps sensor voltage is slightly off, .39 closed throttle, 4.36 WOT. do i need to adjust this?

2. can you clear this up: i ran the car with the iab connected and the stock gsr ecu and there was no cel or power loss at 5800

 

You run the FPR to the small nipple on the front. The rear small nipple gets plugged. The IAB vacuum box gets removed along with the vacuum lines and solenoid.
To answer #1: Loosen the TPS sensor screws. You might have to slot it to use a flathead to turn them. Then twist the TPS in either direction till you get .5v closed throttle and .45v open throttle, then tighten the screws.
For #2: you will not get a CEL if you have the solenoid still plugged in and have no vacuum leaks. You will definitely get a decrease in power up until 5500 or so.

 

ok thanks a lot. but if i wanted to just leave the iab all connected with solenoid still plugged, would this be a problem. i have a type r ecu installed now. would the iab box be doing anything in this case.
