KTuner is currently offering the factory/stock calibration, and one research calibration that is included within the software, but with more to come in the future through software updates. The factory/stock calibration can be used as a starting point to begin tuning from the factory settings. The research calibration (Tune 1) can be ran with 87 octane fuel, but running 91+ will give the best results.Tune 1:
  • Improved throttle response
  • VTEC lowered to 5600 rpm, resulting in broad mid-range power and top-end performance.
  • Supports up to intake and exhaust upgrades. Improperly sized intakes or higher flowing exhausts may throw off fueling and should be properly tuned.

Flash Back To Stock At Any Time

The KTuner software with this Flash System allows you to flash your ECU back to stock at any time.
