Stage 2 Configuration:This ECU reflash was developed using the TST WORX Airbox, M4 Full System Exhaust, and premium 93 octane pump gasoline. We do not recommend this tune for any bike fitted with a different airbox. The tune was optimized for the M4 full system exhaust, therefore we only recommend that exhaust currently. Using a different exhaust may result in suboptimal performance. 93 octane should always be used when operating with this tune.
Description
After installing the TST WORX Airbox on your 2026+ Yamaha YZF-R7, a proper ECU tune is essential to manage the increased airflow and unlock real performance gains. Our WORX Stage 2 ECU Flash was developed specifically around our airbox and refined using the M4 full system exhaust, allowing the CP2 engine to deliver stronger power while maintaining safe operating parameters. Simply send in your OEM ECU and we’ll handle the flashing process. Once reinstalled, you’ll feel the difference immediately, with significant gains in horsepower and torque across the entire rev range, especially at higher RPMs, giving your R7 the performance edge whether you're pushing hard on the track.
NORTH AMERICAN MARKET ONLY: Please keep in mind that this is only available for North American market motorcycles ONLY. All orders placed outside of the North American region will be canceled.
You are responsible for sending us an undamaged stock Yamaha YZF-R7 ECU. We will reflash the ECU and send it back to you ready to be reinstalled. Once an ECU is flashed, all sales are final and no refunds can be issued.
TST ECU Tunes are shipped after we receive and flash your ECU. Any other items in the same order will ship separately on our normal schedule.
