The KTuner Flash V2 Touch is a device that reflashes the factory ECU in the 2017-22 NSX to increase performance by more than 40-60 horsepower, depending on the fuel used (91 or 93 octane). 

Included is a touchscreen programming module that reads the software version on your NSX and uploads maps with higher performance targets. All factory emissions components and engine safety functions are retained. 

The device allows you to store different and change maps in less than 5 minutes. Included maps are:

• Factory Plus: retains OEM boost targets, but increases throttle response.
• Stage 1: 40-60+ wheel horsepower increases (91-93 octane). Increases boost targets and throttle response in all modes.
• Stage 2: 130+ wheel horsepower increase (98 octane or E40 required). Increases boost targets and throttle response in all modes.
• Valet: reduces throttle response and boost targets down to 4 PSI to reduce performance from the engine.

In addition, when not used in an off-road application, the device allows you to switch back to the factory calibration map.
