The ECU is under the plate in the passenger footwell - lift up the carpet and look.

the fcd doesnt plug into the engine computer, it plugs into the pressure sensor on the pasenger strut tower in the engine bay. the main computer is under a metal plate under the carpet on the passgner side under the dash

You shouldn't be modifying stuff like this if you don't know some of the basics like this. I'm gonna assume that you plan to turn up the boost to 12psi and have stock fuel injection?

Can I buy your front rotor housing when your engine blows?

This info is easily found in the Factory Service Manual. If you don't have the FSM, click here and download it in PDF format for free.

While most aftermarket FCD's plug into the boost sensor, there's no reason why they can't be wired in at the ECU. That's where mine is.

I know a lot about the vehicle, just didn't know where the ecu was...... So I don't know why you guys are such *** holes on here... I read a lot about the cars, and I get my hands dirty doing all the repairs so I understand the car a lot more.... that was the only thing I need to know about...... I have a fsm yes but its almost to **** from the previous owner last year... No table of contents in it and I was looking all through it yesterday couldn't find it..... thank you......

ECU is under the passenger side kick panel.

FCDs can be the plug in type or the wire in type.

As far as the ******* comments, not sure on that one.
