STAGE 2 ECU Flash – Triumph 660 

Unlock the full potential of your Triumph Trident 660 or Tiger Sport 660 with our Stage 2 ECU Flash. Developed to bring out the true performance hidden within the factory tune, this remap refines throttle behavior, fueling, and ignition for smooth, consistent power and a noticeably stronger midrange punch.

Performance Gains

Experience a sharper, more responsive ride with increased horsepower and torque across the rev range with up to +15 HP gains at certain throttle points. The RPM limiter has been raised, extending the usable powerband and reducing the need for frequent shifts on track. The top-speed limiter is also unlocked, allowing your bike to reach its true maximum velocity.

Engine Refinement

Our Stage 2 calibration adjusts fueling and ignition tables across all throttle angles for 91+ octane fuel, ensuring smooth and predictable throttle response in every riding mode. The engine also runs cooler and more consistently, delivering stronger off-idle response and improved midrange drive.

The injector cutoff has been refined, smoothing out the overly harsh deceleration found in the stock map. The result? A more natural and controllable ride, especially through corners and at low speeds.

Smart Customization

This tune supports popular performance upgrades like aftermarket exhausts and intakes with a plug-and-play approach no need for additional piggyback units. You can also request custom gearing calibration to match different sprocket setups for track or street use.

A2 Restriction Fix

For A2-restricted models, you’ll need to replace the factory A2 throttle position sensor (TPS) with a non-A2 version, as the restricted TPS doesn’t output enough voltage for full throttle opening. Once swapped, our flash completely removes the horsepower limitation.

Handheld Included

The included handheld tuner allows you to flash your ECU directly at home no need to mail it in. You can:

• Save and restore your stock map anytime.

• Apply updates or custom maps easily.

• Monitor tune information through a simple, user-friendly interface.
