KTuner V1.2 – 2022–2024 Honda Civic 2.0 ECU Tuning System
Unlock the Performance of Your Honda Civic 2.0
Your Honda Civic 2.0 naturally aspirated engine has more performance potential than its factory ECU calibration delivers.

KTuner V1.2 Research Calibration
KTuner is currently offering one research calibration for supported 2022–2024 Honda Civic 2.0 applications.
| Calibration | Features |
|---|---|
| Tune 1 | Improved throttle response, VTEC lowered to 5300 RPM, mid-range and top-end power increases |
The tune can be run with 87-octane fuel, but running 91+ octane will give the best results. Actual results vary by vehicle, fuel, and condition.
