Hi,
I'm selling my O.ct Tuned ECU. It's an 8D0 907 551 "AA" O.ct stage 1 Tuned ECU. I had this in my 2002 S4, before I sold it. For the past 9 months, I've been running it in my Audi Allroad 2.7T, Tiptronic. This unit will fit 2002 Audi S4, 2.7T W/Tiptronic (Probable fits other years of the S4) and 2000 to 2003 Audi Allroad, 2.7T, Tiptronic (If used in the Audi A6 C5, you wont have the Immobilzer 3 enabled, so consider this if using for an A6 C5 application)
This ECU may fit other years and applications, but it's your responsibility to be sure of your vehicles fitment.
I have several performance ECU's and this ECU (O.ct Oberscheider) has, by FAR and away, the smoothest delivery throughout the power range. It's rated at 296 hp. and 362 ft. lbs. torque. So, it doesn't have quite the HP of the GIAC-X (-12 hp.), but it feels every bit as powerful and oh so much smoother. You would have to feel it, to believe its smooth delivery.
If you know about O.ct Tunes, then you know how expensive these tunes, are. I hate to say what I paid for this tune, but I will say that it cost me twice as much as my GIAC-X.
I'm selling my Audi and I'd rather not sell it with this ECU in the car.
I'll let this go for $500, OBO. Please, no low ballers. Also, I'll need your ECU in exchange. So, you can send your ECU with the check, or money order, or you can send a core of $200 along with payment for this ECU.
Like I said, I'm asking $500 / OBO (plus your ECU), or best offer.
Thanks for looking and I'll be glad to answer any questions you may have.
