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 map: retains OEM boost targets, but increases throttle response.
  • Stage 1 map: increases boost targets and throttle response in all modes. Increases power by over 40-60 horsepower.
  • Dual map: increases performance in only Sport+ or Track mode.
  • Valet map: 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.


  • Nothing to install: the initial setup process takes about 15 minutes. After then, maps can be switched in less than 5 minutes. Click here for an instructional video.
  • No tuning required: pre-set maps increase performance automatically and don't require tuning. An extra-cost advanced motorsport tuning suite will be available in the future.
  • Free map updates: additional pre-set maps, including ones for race fuel and ethanol fuels, will be available for free when released.
  • Compact touchscreen programming, gauge viewing, and datalogging device included: the KTuner Flash V2 Touch is an aluminum-housed touchscreen device that allows you to upload flashes to the ECU, view high-speed live gauges, and datalog parameters for later review.
  • Compatible with all current North American NSX: compatible with all NSX years, 2017-22 including Type S. For international users, please contact us for current available software versions before purchasing.
