ecu??

[scotty91]

what ecu should i put in my 91 ex coupe??? and will the h23 intake manifold work?

[heero357]

what engine do u have n the car homie?

[theSOB]

if you have f22a6, u dont have to upgrade. tthe pt6 will work just fine and yes, the h23 IM would work. if u dont have the a6, get the pt6 ecu

[H23CB7]

he has a 91 so its gonna be an f22a4. But its practically the same thing.

[scotty91]

yeah its a f22a4. would an f22a6 cam do good?

[theSOB]

get the pt6 ecu then the a6 cam and h23 IM

[scotty91]

alright thanks man.

[theSOB]

np. i've got a similar plan for my a1. i'm gunna get a bisi stage 2 regrind on my cam instead of a6 though

[GearBangnAccord]

or u can do P12 ECU and the h23 IM

[deevergote]

The P12 is made for a stock F22A1. There is no guarantee that you'll gain anything with any other modifications. It could very well be a waste of money.

[GearBangnAccord]

he has an A4 which is the same as the A1 minus the EM

[deevergote]

Right. Then you add an H23 intake manifold, and it's no longer the same as the A1. The P12 has been hyped to be a much better thing than it really is. It's cool... but I've heard of people paying $80+ for them... and that's idiotic. Pick one up for $15 for your very first mod, fine... but a P12 isn't really a worthwhile addition to any modified setup unless you just happen to stumble across one.

[scotty91]

then what ecu do you think i should put in?

[deevergote]

The ECU you have in there now is just fine. If you get an intake manifold from an F22A6 or H23A, then the PT6 ECU from the F22A6 will work to operate the IAB system properly.

Honestly, the ECU is something that you don't need to worry about for quite some time.

[theSOB]

if u get the h23 IM before the ecu, just bypass the black box underneath for now and connect the butterfly hose directly to the IM, this way you get some operation out of them. then when u get a pt6, go ahead and hook it up to the black box and have fun.
