need 05 wrx ecu diagram and a question - TriStateTuners.com :: Home of Tristate Auto Enthusiast

i have been looking all around for an ecu diagram... short story, i installed an apex turbo timer in my 05 wrx today and when i went to hook up the o2 portion i couldnt find a diagram so i dont know what tires to splice into.

also, i have an invidia catless uppipe, downpipe, and cat-back. uppipe and dpwnpipe are not on the car yet.

what will happen if there is no o2 sensor bungs on the exhaust pipes for my o2 sensor? will it effect the turbo timer/ how will i read air fuel?

i was thinking have a custom 02 bung welded on becasue i dont know if there is a spot for it and i cant check becasue its all packed away right now

anyone know anything about this?

1- that turbo timer's A/F function is worthless on your rex. actually, its worthless period lol.

if you want A/F readings, get a wide band

2- your exhaust pipes should have all the needed o2 bungs. In fact, there are only 1. and an EGT in the uppipe

oh, and ECU diagram

so i should just not worry about the a/f function on the timer and get a wideband a/f gauge?

unless you go with AEMs wideband gauge, you arent going to get a good reading. Talk to ray about one.

RyanG · 11-11-2007, 10:19 AM

you can get any wideband you want. It doesnt have to be AEM. TurboXS's Tuner is awesome, so are the Innovate line of gauges. Just get the best one you can afford

i was gonna get the greddy gauges. either way i want them all to be the same kind and style because i want a clean look.

ps i just sold an AEM wideband a/f
