Description

With our very own Ninja 400 race bike and a shelf full of trophies, it's clear that all of the hard work that our team put into hardware and tune development paid off! They poured hundreds of hours into our dyno and countless laps around tracks across the entire U.S., resulting in us winning the ASRA Moto3 National Championship on our Ninja 400 race bike. We used all of that racing data to develop this TST WORX Stage 2 ECU Tune, ensuring that it's able to deliver power gains you can feel across the entire rev range. It's designed to be installed on bikes equipped with an aftermarket full system exhaust, MWR Race Air Filter, and our TST WORX V2 Velocity Stacks, optimizing the additional airflow within the engine to reliably produce smooth and noticable power gains. If you're trying to pull away from the pack, this tune gives you the boost you're looking for!

EQUIPMENT REQUIREMENT: This tune MUST be paired with the TST WORX V2 Velocity Stacks, MWR Air Filter, TST Emission Block Off Kit, and an aftermarket full system exhaust. Failure to do so will result in poor performance that may fall out of the safe zone of operation.

Please note that if your "Check Engine" light is on previous to an ECU tune, the light will remain on after the reflash and must be cleared manually.

ECU Flashing Explained

Q: Why is this tuned for specific parts?

A: Each part upgrade adds new variables, and we developed this tune to optimize the airflow provided by our TST WORX V2 Velocity Stacks, the MWR Air Filter, and an aftermarket exhaust. Pairing this tune with different or substitued parts may not deliver expected results and may even hurt your motor.

Q: If I already have a WORX Tune on my Ninja 500 ECU, can I get the Stage 3 Tune at a discount?

A: Absolutely! Simply contact our customer service team and ask about obtaining a reflash.

Q: Do I ship my ECU to you?

A: Yes, it is your responsibility to ship an undamaged stock ECU to our facility in Florida for tuning. The ECU must be properly packed and free of any damage or contaminants to be tuned properly.

Q: Where do I ship my ECU?

A: Once your order is placed, our Customer Support team will send you an email with instructions on how to properly package and ship your ECU to our headquarters in Central Florida.

Q: Do I pay for shipping if I am sending you my ECU?

A: Yes - it is your responsibility to properly package your ECU and send it to our facility in Florida.

Q: What is the turnaround time after you receive my ECU?

A: Our tuning turnaround time is only 1-3 business day.

Q: Should I remove my 02 sensor?

A: Yes, remove your O2 sensor for optimal performance while runing this tune.

Q: Do I need to block the AIS / Install smog block off plates?

A: Yes, you should block the AIS for optimal performance while runing this tune.

Q: Should I remove my charcoal canister if my bike is equipped with one?

A: That's up to you. The charcoal canister won't effect the performance of your ECU tune, so there's no need to remove it. If you do decide to remove it, be sure to check with local laws and regulations.

Q: Will I need to send my ECU in again for a new tune if I install a different exhaust?

A: If your new exhaust is listed as a upported option, we highly recommend sending your ECU back in for a retune. If not, it is not needed.

Q: My exhaust isn't listed, can I still get this tune?

A: Yes, we can install a compatible tune even if your exhaust is not listed. You will see benefits compared to the stock tune; however, the tune installed may not be optimal for your setup.

Q: What is your return and warranty policy?

A: Returns are not accepted for this item. Please read over our policies thoroughly on our terms and conditions page BEFORE making your purchase. TST Industries Terms and Conditions
