ECU Flash Tuning for 2026 Kawasaki Teryx H2
Evolution Powersports offers advanced ECU tuning for the Kawasaki H2, developed through over 500 dyno pulls and extensive field testing. The tuning adds ignition mapping by boost pressurea feature missing from the OEM Kawasaki Mitsubishi ECUto safely deliver higher than stock boost levels.
Multi-Map Tuning Available
Switch between 91 and 100 octane tunes using the vehicle's High/Mid/Low driving modes with an included Safety Rocker Switch, without reflashing the ECU. The safety switch requires users to release a lock to operate, preventing accidental octane switching.

Dyno runs performed at EVP's Wisconsin R&D center. Performance may vary based on atmospheric conditions and altitude. Horsepower gains result from a combination of EVP Stage 3 or 4 Tune with EVP Shift-Tek Mag Clutch Kit and stock or EVP exhaust components.
Important Notes on Supercharged Performance
The Kawasaki H2 uses a crank-driven supercharger and is highly susceptible to changes in density altitude. Correct clutching RPM is essential to realize gains. The engine requires higher than stock RPM to produce more than stock boost. 100 octane tunes use advanced ignition timing and raised RPM for additional power. Performance shown represents power near sea level in fall/winter conditions. As elevation, temperature, and humidity increase, power output decreases for both stock and tuned engines. EVP exhaust systems and blow-off valve also provide significant positive impact on performance regardless of density altitude.
