Dynojet expanded its Power Commander V lineup in December 2013 with a fuel-and-ignition controller developed for the original 2014 Polaris RZR XP 1000.
The module allowed owners and engine builders to adjust fuel delivery and ignition timing without replacing the factory ECU. It was particularly relevant for XP 1000s equipped with aftermarket exhaust systems, intake components or internal engine modifications that required more precise calibration.
Tuning the Original RZR XP 1000
Polaris introduced the RZR XP 1000 with a 999cc ProStar parallel-twin producing a claimed 107 horsepower. The engine used electronic fuel injection, dual 48mm throttle bodies and long-tip fuel injectors.
More than 80 percent of peak torque was reportedly available from 3,500 rpm through redline, giving the new machine considerably stronger acceleration than the RZR XP 900 it replaced.
The Power Commander V intercepted signals between the factory ECU and the engine, allowing its calibration to be adjusted through Dynojet software. Owners could load compatible maps or have the vehicle professionally tuned to match its specific combination of modifications.
Dynojet Power Commander V Features
- Fuel-delivery adjustment across the engine’s operating range
- Built-in ignition control for supported applications
- USB-powered programming from a computer
- Two-position map-switch input for changing between compatible maps
- Gear and speed inputs for gear-dependent adjustments
- Analog input for compatible 0–5-volt sensors
- Individual cylinder fuel and ignition adjustments
- Adjustable acceleration-pump function
- Rev-limit adjustment where supported by the application
- Built-in launch-limiter capability
The controller provided a fuel-adjustment range of minus 100 percent to plus 250 percent and used 10 throttle-position columns for more detailed calibration. Dynojet also offered optional accessories that could expand the system’s tuning and data capabilities.
Why Proper Fuel and Ignition Tuning Matters
Installing an exhaust, intake or other performance component can change the amount of air moving through an engine. A compatible fuel controller gives a qualified tuner the ability to adjust fueling for those changes instead of relying entirely on the original calibration.
A tune should be developed for the vehicle’s actual engine and modifications. A map created for a different exhaust, intake or engine configuration may not deliver the same results. Dyno testing or monitored wideband tuning is preferable when substantial performance modifications are involved.
Current Availability
This article documents the Power Commander V application announced for the 2014 Polaris RZR XP 1000. Product availability, replacement components and software support may have changed since the original announcement. Dynojet continues to maintain a vehicle-specific tune-download page for the 2014 RZR XP 1000, but owners should confirm hardware compatibility and current availability directly with Dynojet before purchasing used or new-old-stock equipment.
