    Does anyone have one ?
    How do you like it and does it do everything you wanted ?

    Is the connection a plug and play? and if using the OBDII plug under steering column - does it stick out a lot ?

    i think it does the same thing that the ECUTEK data monitor does

    i have the ECUTEK monitor and i couldn't be happier... good thing is that it reads off the stock sensors so u see what the ECU sees... bad thing is that it reads from the stock sensors so AFR is narrowband... also i never got reliable EGT readings on the WRX or the STI (though others have had decent readings)... but that could just be the sensor

    is the EGT (reading) from the Elbow on the exhaust manifold near the UP ?

    Yeap, I have one too. I just need to get it mounted in the 06. I have seen the AFR go as rich as 10:1 and as lean as 15:1 so its not too narrow.

    I really liked it in my old WRX.

    Milo, How well does it work with the Cobb Protune?

    i have seen lean over 20:1 when rolling down the highway with my foot off the gas... but i have never noticed it read below 11:1... i should see if it does it
    works nicely... if u were happy with it stock then u will be happy with it after the protune :)

    oooh... i just realized something... i should probably go out and see if it lets me play with the usertune... wonder if it will let me since i dont have an ecutek license

    I need to get my monitor hooked up to my car stock. Then I can see how rich it goes. We all know that the stock WRX is pig rich from the factory. I always had a Ecutek tune on my old car when I had the monitor. If I get a new head unit cheap then I will get it installed.

    That actually sounds like that could be correct, on decel there really shouldnt be very much fuel introduced. So i would imagine the AFR would be rather lean. Not sure tho.
