The Polaris RZR/ EJK Controller By Dobeck is a customizable solution for those wanting to be in charge of the tuning needs of their machines. It takes next to no time to install as it is plug and play and it is so simple to use that from beginners to experts can use it. When we say Plug and Play we mean even more than just the installation process. We mean that you will have chosen a programmed and ready to go option to manage your modifications. Your tune-up generally leaves your machine riding smoother, but imagine being to tailor it to your specific driving style. Two important things you should know are that when you shut off your Side x Side it is normal for the LED’s on your controller to remain on for a bit. The second thing to note is that this controller is only available to order over the phone. It’s not as tedious as it sounds, as a matter of fact when you think of it, the ordering process is the beginning of your convenience experience with this controller.
Controller is protected by a MAP (minimum advertised price) policy.
This controller is NOT California ON-ROAD approved.
CARB E.O. D-654 controller available by phone order only.
Controller LEDs on after shutting off your UTV is NORMAL.
7/1/2016 - ECU codes 65590, 65591 and 65592 - May occur after getting the Polaris recall in April 2016 completed. They are cylinder misfire codes for cylinder #1 and cylinder #2. These codes are not in the service manual and will only come up once the ECU has been re-flashed due to a Polaris recall. MAIN CAUSE has been related to the belt which may have too much deflection or may be slipping. Polaris suggests to change the belt out with a new one and/or replace spark plugs.

| Feature Name | Description |
| NONE | Feature is NOT enabled and will be skipped over when navigating through features with MODE button. |
| GREEN FUEL | Feature allows fuel adjustment when the Green zone is active which is typically during idle and cruising conditions. |
| YELLOW FUEL | Feature allows fuel adjustment when the Yellow zone is active which is typically during acceleration conditions. |
| RED FUEL | Feature allows fuel adjustment when the Red zone is active which is typically during full throttle conditions. |
| GRN LWR SW PT | Feature allows adjustment of when the Green zone engages. Typically relates to an RPM value to determine if fuel adjustment should be allowed at idle or not. |
| YEL LWR SW PT | Feature allows adjustment of when the Yellow zone engages. |
| RED LWR SW PT | Feature allows adjustment of when the Red zone engages. |
| ACCEL PUMP FUEL | Feature allows fuel adjustment when the Accel Pump is active. |
| DECEL FUEL | Feature allows fuel adjustment when the vehicle is de-accelerating at a moderate to high rate. |
| GRN UPR SW PT | Feature allows adjustment of when the Green zone shuts off. Typically relates to an RPM value to determine if fuel adjustment should be allowed above a mid-range cruising RPM. |
| VCA SW PT | Represents transition between factory open loop and closed loop. When the LED display shows a solid BLUE light in the 8th position then the controller is interfacing with the ECU closed loop mode. Mode rarely needs to be adjusted. |
| CLOSED LOOP FUEL | Feature allows fuel adjustment when the VC zone is active. Feature implements an indirect fueling method where the O2 signal is being manipulated which causes the ECU to make fuel changes. Only affects fueling while ECU is in closed loop mode. |
| VC OFFSET | Voltage Control Offset. Given a sensor input signal between 0-5 volts this feature will offset the voltage a varying amount. |
| MAX BOOST PRESSURE | Represents the maximum amount of boost pressure the vehicle can produce. |
| MAX PRESSURE FUEL | Feature allows fuel adjustment when Pressure zone is active. |
