  • Live data display option
  • free tuning updates
  • custom tuning not supported at this time.
  • OTS Development maps (1.05 release) for 87,91 and 93 octane


    Things that are calibrated in this tune are and what they do :


    Throttle response  and Throttle Curve 


    Valve Timing - Torque 


    Torque control maps - Shifting control, Shift firmness, 

    Torque request maps - maximum allowable torque

    Shift control maps - upshift and downshift control maps for every gear. Dynamically changes driving experience

    Ignition Timing - Torque, Horsepower, Smoother power delivery

    Fuel Mapping - Torque 

    and much more


    HP / TQ gains: 15-20 focused in mid range (2500-4500 RPM)

    TQ gains of 20-30+ ft lbs at 3200 RPM

    Peak top end HP gains 7-9HP (measured at wheel) (stock vehicle 91 octane)



                                   OVTune Alpha 1.01 Reflash- stock vehicle 91 octane
