    Calling ALL WRXs with a UTEC...

    Wasn't sure where to post this, so I stuck it in the "world" section!! Anyways, TurboXS is going to make a UTEC for the SRT-4 and I wanted to hear from the WRX owners that have it installed on their cars.

    How easy is it to manage?
    What is the minimum requirement for a laptop?
    what does it control in the WRX?
    Any glitches, headaches or problems?
    How easy/hard is it to install?
    Warranty problems/issues?
    Do you set it and forget it, or are you always tuning it?

    That's it for now. I thank you in advance for taking the time to answer my questions!!

    UTEC

    How easy is it to manage?
    I find it very easy to manage. Tuning your car properly is another thing...

    What is the minimum requirement for a laptop?
    Must have HyperTerminal installed (or other terminal software). I use a Pentium 233.

    what does it control in the WRX?
    You have an absolute timing map (based on Mass-AirFlow sensor), a fuel trim map (based on MAF) and a Boost map (based on Throttle Position Sensor).

    Any glitches, headaches or problems?
    Nope.

    How easy/hard is it to install?
    Took me about 1.5 hours, but I'm a mechanical wimp.

    Warranty problems/issues?
    With the Subaru or with TurboXS? None and none.

    Do you set it and forget it, or are you always tuning it?
    I'm always tweaking and datalogging, but that's my nature.

    Re: Calling ALL WRXs with a UTEC...

    1. How easy is it to manage?
    1. The interface is VERY simple, and effective. As above, tuning is an art.

    2. What is the minimum requirement for a laptop?
    2. Not sure, but it runs fine on my P166 IBM Thinkpad from the EARLY 90's

    3. what does it control in the WRX?
    3. Ignition and Boost DIRECTLY, Fuel by MAF voltage modification

    4. Any glitches, headaches or problems?
    4. Very few. Firmware updates usually take care of them, TXS is on the ball.

    5. How easy/hard is it to install?
    5. 30 mins. to install, candy. Manual has been updated since I installed mine so should be easier.

    6. Warranty problems/issues?
    6. None.

    7. Do you set it and forget it, or are you always tuning it?
    7. ALWAYS tuning. This is not a set it and forget it piece. There are much better solutions for someone who doesn't want to tinker. I bought a WBO2 sensor ($550 used!) just to get this thing dialed in, and to keep it dialed in. ALWAYS logging, always tuning, always using it to see what's going on... But that's the beauty for me. I'm a natural tinkerer.

    Good luck!

    1. It is easy to manage

    2. I dunno the minimum, but I bought a used laptop for $200 and it works. It's a pentium 133

    3. Fuel, ignition timing, and boost are programmable in 250rpm increments up to 9000rpm over 10 load sites

    Complete ignition timing control
    No need to worry about the factory ECU pulling timing anymore
    Be as aggressive or conservative as you want or just let the factory ECU determine timing at any point in the map

    Fuel control
    Controlled via MAF sensor signal offset
    Tune stock and larger than stock injectors

    Load reference
    MAP (manifold pressure)

    Closed loop boost control programmable via Throttle Position and RPM
    No more re-adjusting the boost controller due to changes in temperature or altitude
    Keeps boost low while in closed loop fuel mode for reliability

    Knock control
    Automatically retards timing when the knock is detected safeguarding against engine damage
    Adjustable knock threshold, timing correction, and duration

    On board data logging
    Provides valuable information to assist you in tuning

    Built in programmable solenoid controller
    Control nitrous, water injection, intercooler water spray or any other solenoid device

    Free software upgrades
    As we add more features, simply download the latest software version from our website and upload it to the UTEC

    Drag racing launch control (secondary rev limit used during launch)
    Shave precious time off your launch


    4. no problems

    5. install is plug and play 5 minutes

    6. warranty issues? I don't understand the question but if you're using an ecu i'm sure they're not going to warranty it. You can remove it without them ever knowing it was installed or you can take resposibility for your actions and leave it.

    7. I'm always tuning to get max power but if you want to settle you can. I'm always getting new mods too, so have to tune for them.

    This is GREAT GUYS!! I really appreciate it!!

    The kind of information does the data logging give you?

    Seeing that my car suffers a little in the traction department, I can set the exact boost I want at any given RPM (250 interval)?

    Does it hold your settings accurately?

    Datalogging has lots of info, off the top of my head I can think of

    RPM, throttle position, load point. boost, timing, injector duty cycle, knock counts, etc

    Boost is set via RPM vs TPS (throttle position)


    So yeah at low rpms you can start with low boost and increase them as you go higher, all though most people want to build boost asap.

    Yes it holds settings accurately, boost will change a bit (spiking) with the colder weather but that's normal.

    I agree with what others have written so far. Another advantage is that (in the WRX), it flashes a CEL if you have knock. If you get a tank of bad gas, you will knock. It's nice to have that visual warning and will let you either bump up the octane with toluene or just drive out the rest of the tank at low boost.

    One possible downside is that with changes in outside temperature, you will have to make adjustments to your ABC (a bleed valve) to control boost when in open loop boost control. Closed loop boost control is supposed to fix this but some people have said that it is still an issue.

    Overall, its a great product.
