How It Works: 

- Once you receive our ECM Tuning Package you load our software to your windows laptop. (A windows laptop is required and not provided! WINDOWS XP IS NOT SUPPORTED!). You register your software and dump the binary contents of your stock ECU.  We then provide you a modified binary to load to the ECU with all of our latest developments. 


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
