    GIAC Stage 3 BW K04 ECU 93 oct/E85

    Guest-only advertisement. Register or Log In now!
    Asking 400 plus shipping OBO

    GIAC E85 ecu with Stock, Pump(93 Oct), Race(E85), Valet and Kill(anti-theft) modes. Each file has three selectable power levels. For use with 85mm maf and BW K04 turbos.

    Comes with hand held Flashloader for switching between the files(fuels) easily

    GIAC specified brand new FIVEO motorsports injectors which flow 63.8lbs(670cc) at 4bar.

    This tune was advertised as an OTS tune for K04s or F21S, 85mm Hitachi maf, 013U575 injectors, Upgraded E85 compatible pump(450 or 044), 4 bar fpr(stock), 3 inch dps, upgraded intercoolers.


    I ran this set up with K04s and a complete RS4 intake set up along with the tuner bipipes and with water injection. I was able to get some runs on a mustang dyno and the second run made 491hp/511ftlbs which was the highest of the four runs. Ran a 2.9 fats.

    Would only recommend running the e85 file on a car with rods..
