RTD4 CONFIRMED
HP Tuners currently identifies the 2026 Can‑Am Defender HD11 as RTD4-compatible. Other BRP models use an MPVI interface depending on model year.

Remote pack
Complete Custom Remote pack for the 2026 Can‑Am Defender HD11: HP Tuners RTD4, BRP OBDII adapter cable, data logging and HP Tuners credit pool included with the bespoke PNP TUNE tune. The required MG1 unlock is not included. Custom Remote: dedicated calibration through data logging, with real-data analysis and remote adjustments. Removal of the factory speed limiter is included: a Can‑Am limited to 60, 90 or 105 km/h is unrestricted from the first level. On a Sea‑Doo or a Ski‑Doo it is the ECU ceilings that open up: revs, torque, driver demand and boost. On a Sea‑Doo RXP-X 325 or RXT-X 325 the GPS speed limiter goes too, with the MG1CA920 unlock at HP Tuners (Powersports MG1 ECM Service): 80 mph and more, around 129 km/h, factory rev limiter kept. With Custom Remote, data logging lets us go further still on top speed.
