STi computer reflash

P

Philip Procter

Has anyone here ever had the eprom in their STi reflashed or added an
outboard engine controller?

I'm new to this modern perfromance game and was wondering what your
experiences were. I've had more than one company tell me that almost
the first thing you should do is reprogram the computer. The Sti, in
particular, is programed very conservitivly.

Then again, they're all trying to sell their stuff!

While I don't drive an STi, I do drive a WRX that has a piggyback ECU (UTEC
from turboxs). This was one of the first things I added to my car and can
honestly say that I picked up 23 WHP and 18 ft/lbs of torque just by
installing this (dynoed it before and after to get an idea). Other friends
of mine have done the Cobb Accessport option, Vishnu Exede, and
Elementtuning ECU. For ease of use I'd say the Exede/Accessport options
are probably the best, but if you are looking to do more mods after you get
going then I'd look into the UTEC for sure or maybe even the Elementtuning
ECU.
 
Did you get the UTEC stage 1 or 2? Just interested...

I want to put a stage-1 in my MY05 WRX...and then replace the up-pipe later
on and wonder about the need to go stage 2 after that or can I stick to
stage 1? I don't wana go too aggressive and lose all my mileage. What
kind of change in MPG did you get? The way I drive right now on my stock
WRX I get around 20mpg (city, short drives. 25 for long highway trips), if
that tells you anything....
