This ECU reflash was tuned using 93 pump gasoline. 93 octane should always be used when operating with this tune. AIS should be blocked off for optimal results and to avoid excessive popping during deceleration. O2 sensor connector should be unplugged to ensure proper results. This tune is suitable for stock or aftermarket air filters.

Description

The 2021-2025 Kawasaki ZX-10R brings formidable performance to the track, but its stock ECU calibration limits much of the engine’s potential at higher RPM. The TST WORX Performance ECU Tune recalibrates fueling, ignition timing, throttle mapping, rev limits, and engine-braking behavior while also eliminating restricting factory settings. Combined with a full or 3/4 aftermarket exhaust, it produces 13% more peak power than a completely stock bike and a 10% increase over the same exhaust configuration running the factory tune. The most dramatic improvement arrives at 13,500 RPM, where revised throttle mapping delivers gains of 70% over the stock motorcycle and nearly 60% over a full-exhaust setup running the factory ECU tune. The result is a harder-pulling, more responsive ZX-10R engineered to deliver its best performance on the track.

AFTER TUNE: Please be aware that the Check Engine Light will be on and the Riding Mode and KTRC will flash after reinstalling the ECU. All of these will clear after one or two rides of at least 35-45 MPH.

NORTH AMERICAN MARKET ONLY: Please keep in mind that this is only available for North American market Kawasaki ZX-10R motorcycles ONLY. All orders placed outside of the North American region will be canceled.
