im trying to see if my vtec is hooked up right? do i need IABs for the vtec to work in a h22a. i have a h22a in a 94 integra, where do i look for the knock sensor? what color is it. i have a p28 . is it already set for vtec? i dont see why it isnt. it has a launch and rev limiter

 

all u need for the vtec to work is vtec oil pressure sensor and vtec activator hooked up , as for knock sensor (back of block near head color is green ) above oil pressure sensor..

 

some computers do need the knock sensor for vtec to work. mostly because you'll be throwing code 23. I had the same problem and to replace it was over a 100 bucks at honda. Its kinda hard to see unless your under the car. Just reach your hand under your intake manifold and you should feel the sensor. I believe it will have one wire coming out.

 

P28 doesnt look for a KS, but the KS is located on the backside of yer engine right below the intake manifold. Here's an image of a B18C KS, which is in a similar location on your H22, and its normally a black color...



you dont need the IAB's hooked up in order for VTEC to work.

 

ur right the plug is green ,the wire is blue w/red tracer

 

where is the oil pressure switch located? what wires to i need to hook up for vtec to work. and where are they located. what pinouts do they go to on the p28 ecu?

 

pressure switch is next to the vtec solenoid. lite blue to d6 ,black w/red to ground

Any thoughts on running a p28 and still having a way to use the stock knock sensor with a remote setup to deal/monitor knock?

...thoughts? yeah of course...a J&S Safegaurd comes to mind.

Meh... ballah. I've had a custom setup suggested and thinking of giving it a shot... I hope I can remember all my engineering stuff and pull it off.
