Description
Description
This Stage 2 competition ECU flash for the Ski-Doo 850 Turbo recalibrates your factory ECU to deliver up to 205 horsepower on 91 octane pump gas, with installation through the factory diagnostic port and no wiring or splicing required. The package includes a clutch kit (141-112) and is compatible with 2024 through 2027 Ski-Doo 850 Turbo models.
Beyond the power gain, the flash adds built-in diagnostics for reading and clearing fault codes, real-time system status, and data logging of boost, RPM, throttle position, and temperatures that can be saved or exported for review. All functions run directly from your cell phone, so no laptop is needed.
