2026+ Can-Am Defender HD11 ECU Tuning and Unlock - Stage 1 91 Octane

Unlock the true potential of your Can-Am Defender HD11 with EVP’s Stage 1 ECU Flash —a performance upgrade that delivers dramatic gains in horsepower, throttle response, and overall drivability. With over 25 horsepower gained right off the hit, this package transforms the HD11 into the machine it should have been from the factory.

In stock form, the Defender HD11 is known for sluggish acceleration and muted throttle response, recording a 0–60 time of 16.85 seconds. After extensive testing and development on Can-Am’s three-cylinder Rotax platform, EVP has refined a tuning strategy that fully unlocks the MG1 ECU's capabilities. The result is a night-and-day improvement in performance—cutting more than 3 seconds off the 0–60 time, now clocking in at 13.53 seconds.

EVP’s MG1 ECU tuning is engineered for reliable, repeatable power gains. The calibration raises rev and torque limits, remaps fueling and ignition timing, and incorporates multiple safety strategies to ensure consistent performance in all riding conditions. Integrated cooling fan control allows users to choose stock fan settings for colder climates or reduced fan-on temperatures for hot environments, helping maintain optimal engine temperatures year-round.
