Match Your Model and Build
Trail S 1000, S 4 1000, XP S 1000, XP S 4 1000 and 2024+ XP 4 1000 packages use the build-matched 91-octane tuning selection. Provide your model year, ECU and hardware so FastUTV can match the calibration.
Provide the model year, full model/trim, ECU details, intended fuel, injector setup, exhaust and intake modifications. Trail S, S4, XP S and four-seat configurations use files matched to their own ECU and hardware.

Stages marked “reference only” describe published chart configurations. Contact FastUTV to discuss the file that matches your vehicle and installed hardware. For other 1000-family models, the calibration and expected results are determined from that model’s ECU and build.
MG1 ECU Preparation
For 2024 XP 1000 vehicles with an MG1 ECU, the original ECM requires the HP Tuners MG1 upgrade service before RTD4 diagnostic-port tuning. Contact FastUTV for the required ECU service route and quote. Other MG1-equipped vehicles are checked for their model-specific preparation requirements before tuning.
The documented 1000-family stage references use 91-octane gasoline and stock injectors. Match aftermarket exhaust/intake hardware to the selected calibration.
