Default ECU Info

Hi guys,

I'm going to start a new project soon hopefully and want to start gathering bits. I'm after a ECU. I'm looking for something thats plug and play and don't really want to go with Motec etc.

I understand Power Fc's are great but not cheap
I would like to have some info about the OEM stuff.

I got a whole engine and matching loom that comes with the ECU etc. But i'd like to look for a better ecu as i'd like to put a front mount intercooler and raise the boost a little.

Everything i have is from a 99 WRX. Don't think its STI. I'll post some pics up tomorrow.

I've heard STI Ecu are better and i'm looking for something a little better that can be pluged and play

What do i need?
How do i know what the 380 injectors look like?
What version STI Ecu's would fit?

Would the following be classed in order of increasing performance?

1.... W9 ECU -WRX RA
2.... v1 sti ecu
3.... V2 GF8 STI Ecu
4.... SA ECU (STI CHIPPED) - V STI 14.94PSI

Sry for my ignorance, i'm still learning
Thx

P.s If you have what i need let me know

Front mount is wank with a stock engine & stock ecu.

Version V ecu's aren't 'Sti chipped'

99 engine & harnesses will require 99-00 ecu either a stock wrx one or a version 5 or 6 sti one.

You can't mix and match stock ecu's beyond common year for year models.

If your motor is an Sti ej207 the inlet manifold will be red.

all 99/00 wrx/sti had yellow top 440cc injectors.

Is it worth putting a STI ECU with a front mount?
The turbo is a TD04L. Is that a good turbo or like you say wank?
Yes the Engine has yellow injectors but no red manifold.
are yellow injectors 440cc?


Here are some pics

Fmic with a stock ecu regardless of which one will be laggy as all fk.

That's a 99-00 Wrx ej205.

Yellow tops are 440's as previously stated.

^ i think you should do a quick search before someone like rossco flames you

they will say, why FMIC? its up to you to change the turbo, so many people have good numbers and still no FMIC... have a look at roughstilling's thread

i am a noob and new too, i wanted to have a FMIC, but look at cost, effect= fuck all, effort= more and for what? its got longer pipework and in most cases with aftermarket system requires cutting of your bumper. also things like stones and bugs and shit love FMIC. also more problems with fmic also. after knowing all this would i still get one? no. same as brembo brakes to some sense. people wouldn't even recommend aftermarket TMIC but stay with the STI one becasue they havn't even been able to prove thats its better.

when i joined i knew jack, but i just searched and learned not to get flamed. i am still learnig heaps but everyday

good luck Guy

The engines out man so now's the time to do all your research.

See what numbers people are getting and if their build allows you to reach your goal.
