FS: 02-05 Subaru WRX TURBOXS Engine Management System UTEC.
You are looking at a used TURBOXS Engine Management System Computer (UTEC). This unit is in perfect working order and was only used for about six months prior to me selling my 03 WRX bugeye. This UTEC computer has a tunned MAP loded that was custom made for my WRX. Map was tunned for the fallowing modifications:
Full turboback ehxaust
This auction also includes a used manual TURBOXS boost controller for the higher bidder. Boost controller is in perfect working order.
Computer serial cable
Boost controller & 8inch vaccum line
This item is currently listed on eBay, here is a link for it:

Free software upgrades
As we add more features, simply download the latest software version from our website and upload it to the UTEC.
How does the UTEC increase WRX engine performance?
allowing the user to tune more aggressive ignition timing, air fuel
ratios and boost curves. With 36 RPM sites from 250 RPM to 9000 RPM and
10 load sites, the UTEC gives you 360 possible map points for fuel,
ignition timing, and boost.
How much extra power can I expect from the UTEC?
This really depends on the other modifications you have done to your
WRX. The UTEC will let you get the most out of whatever hardware you
have on your WRX. On a stock WRX, power gains of 30-40 horsepower at
the wheels are easily and safely obtained. Adding a freer flowing
exhaust, a larger turbo, an upgraded fuel system, etc. will allow even
larger power gains. Our staged upgrades will allow you increase
horsepower from between 40hp to over 120hp more than stock. We have
used the UTEC on our personal WRXs to make even more power. Ultimately,
how much power your WRX makes with the UTEC will depend on how well you
have prepared the car’s power train and how well the car is tuned.
Is the UTEC a piggy-back computer or a stand alone engine management system?
The UTEC is a really a bit of both. It acts as a stand alone system in
that it gives you complete control over ignition timing, fuel and boost
under load. The factory ECU is also used to manage some of the more
mundane functions that are necessary to keep a car drivable on a daily
basis. Some examples are cold start, hot start, and closed loop fuel
control under cruise conditions.
Does the UTEC run low impedance injectors?
Do I have to start from scratch and do all the tuning myself?
No. The UTEC comes pre-programmed for various sets of modifications
like exhaust, turbo chargers, fuel system upgrades, etc. Although these
maps may not be a perfect fit for your exact modifications, they will
get you close. However, you will need to fine tune the setup. If you
stick to our staged upgrades, you may not have to do any tuning at all
if you do not want to.
Can I blow up my engine with the UTEC?
Absolutely! If improperly tuned, the UTEC will give you the ability to
destroy your engine in short order. However, as long as your
modifications match our kits, our pre-programmed maps offer a good,
safe starting point.
What are some of the ad vantages of the UTEC over other engine management systems?
The UTEC comes pre-programmed for a given set of modifications so you
can simply plug it in and drive away, yet it is also user tunable
allowing you to take full ad vantage of your modifications. It also
allows you to create and store up to 5 different programs that can be
used at the turn of a dial. There is no need to drive around with your
laptop simply to change from one map to another. Maps are easily shared
with others via e-mail. You can go back to stock setting with the turn
of dial. Data logging is included. The list goes on and on.
Does the UTEC modify the original factory engine control unit?
No. The factory engine control unit is not altered in any way. Removing
the UTEC puts all engine management control back in the hands of the
unaltered factory ECU.
How do I install the UTEC and how long will it take?
The UTEC simply plugs in to the factory ECU using OEM connectors.
Installation takes no longer than 30 minutes and requires no cutting of
wire or soldering. Most of the time is spent simply gaining access the
factory ECU that is under the carpet in the passenger foot-well.
Who can tune the UTEC?
With a little practice and patience, our belief is that anyone can.
What octane gas should I use with the UTEC?
suggest you tune your car on the best gas that is readily available in
your area. We’ve created our street maps using 93 Octane unleaded
gasoline. If you run a lower Octane gas, you will have to modify the
What else do I need to effectively tune the UTEC?
While tuning can be done solely on the road, tuning is most effective
when done on an AWD dyno combined with road tuning. For the most
accurate fuel tuning you will need a good wideband O2 sensor that is
accurate down to at least 10:1. The UTEC logs AFR from the front O2
sensor, but it is only accurate down to about 12:1, which is too lean
for normal pump gas. Narrow band AFR gauges that work off of 1V O2
sensors are useless for accurate fuel tuning. For accurately tuning the
UTEC's Knock Correction system, some form of knock
amplification/detection hardware is required.
