Want an ECU sent to you instead of shipping yours to our shop for flashing? Select the "OEM ECU Core Charge" option to be sent one of our core ECUs, and if you want a return of the $300 core charge, simply send us your unmodified OEM ECU for a core charge refund. Stock levels vary so we may be temporarily out of the ECU cores specific to your bike, and in that case, it is required to ship your ECU in for flashing. Still not sure about Core Charges? Click HERE to learn more.

If sending in your ECU for a core charge return, your ECU part number MUST MATCH the ECU part number of the one you select and receive in your order. WE ARE NOT ABLE TO ACCEPT AN ECU IF THE PART NUMBERS DO NOT MATCH.

Yamaha YZF-R3 | 2015, 2016, 2017, 2018, 2019, 2020

Bundle Features

  • All "bolt-on" items that don't require permanent modifications to your Yamaha R3 or MT-03
  • Improves total engine performance with a unique parts pack with TST WORX specific tune on OEM ECU 
  • Smooth and rideable power delivery
  • Immediate and noticeable change in engine performance and output
  • Increases performance across the whole RPM range
  • Improves acceleration and top speed
  • All parts fully optimized to work together for total performance increases
  • Dramatic weight savings when compared to stock components
  • Tune and all testing performed using the Yoshimura ALPHA-T Full System Exhaust - Other full system exhaust *should* deliver similar results

Performance Numbers

When all parts are properly installed, below are the expected results when paired with the optional Yoshimura ALPHA-T Full System Exhaust

PERFORMANCE ASPECT DIFFERENCE COMPARED TO STOCK
Horsepower 24% Increase in area under the curve*
Peak Horsepower 15% Increase
Torque 20% Increase in area under the curve*
Peak Torque 3-7% Increase - dependant on gear
Weight Savings 11.36 lbs

Area under the curve (also called engine potential) is used to represent total engine performance increase as it takes into consideration the gains across the entire RPM range, not just increase in a peak number.

*Premium 91-93 octane fuel is required for expected results and safety against knock.


Description

After over a thousand dyno runs, multiple test bikes, numerous lap records, and one MOTO3 ASRA National Championship trophy, the TST WORX Pack was born. Our engineering team spent over a year performing research, testing, and refining the parts package that you see here. Every component was chosen or specifically designed to be entirely bolt-on, meaning that you don't need to permanently modify your R3 or MT-03 in any way and that you receive the highest performance boost for your dollar that we could design. With every part optimized to work with the entire parts package, the TST WORX Tune is the icing on the metaphorical R3 / MT-03 cake that elevates this package to another level and takes full advantage of the components. Tuning each cylinder individually enabled us to refine the performance of the engine for not only increased performance and peak power, but overall rideability and power delivery. The smooth power output and increased torque and horsepower combine to provide an immediate and noticeable increase that is sure to slap a grin on your face every time you turn the throttle

Please see the "What's Included" tab to learn more about each individual product in the WORX Pack.

No OEM ECU Core Charge

Select this option if you want to send us your OEM ECU for us to tune and send back to you. You are responsible for shipping the ECU to us originally, so please be sure to pack it neatly with proper padding. Average turnaround time is 2-3 days, depending on any weather or family emergencies. Please print off your order confirmation and include that with the ECU.


OEM ECU Core Charge

Select this option if you want to receive one of our core ECUs that is already flashed. This option enables you to have two ECUs and minimal downtime for installation. If you don't need your original OEM ECU, you can send it back to us and receive a Core Charge refund of $300. It is your responsibility to properly package and ship the OEM ECU when requesting a core charge refund. Please ensure to include the original packing slip and that the OEM ECU is free of any damage, modifications, or contaminants. Your ECU part number must match the part number of the ECU you selected and received and must not be previously flashed with any technology other than FTECU. To read our full policy on Core Charge Refunds, please see our Terms & Conditions page.

If sending in your ECU for a core charge return, your ECU part number MUST MATCH the ECU part number of the one you select and receive in your order. WE ARE NOT ABLE TO ACCEPT AN ECU IF THE PART NUMBERS DO NOT MATCH.
