Arctic Cat - 53 Pump Gas

Kit Description

Making 185 hp, this kit runs 6 psi of boost. Kit comes with all necessary hardware and instructions. Have our professional install facility install and setup your kit.  Upgrade your kit with Clutching, Guages and vent panels.

Electronic Jet Kit Instructions M, F and Crossfire 6, 7 and 8

Our technology interfaces with your fuel injected vehicle to allow EFI tuning based on carburetor logic.  Our product gives you the equivalent of enriching the pilot jet and mixture screw (Green mode), raising the needle (yellow mode), and installing a larger main jet (red mode).  We also allow you to subtract fuel (yellow/blue mode).

Due to the wide variety of applications we try to be very generic with our instructions, if you need further assistance with an install, call tech support at 1-780-988-8726.

This product is capable of handling the fuel needs for a number of aftermarket modifications including:  pipes, air intake, big bores and a variety of porting.  If you find your modification requires even more fuel than allowed by this unit, contact our tech support and we can create a custom application.

This is an Electronic Jet Kit.  Like jet kits in the past, the more you modify, the more responsibility you take in getting your fuel curve right.  In the vent you fail to create a better tune-up, we suggest contacting our tech line for some base settings and tuning help.

Some vehicle modifications with Boost Wurx Inc. products may NOT be permitted for use on public roads and in some cases may be restricted to closed course competition.  Those products NOT identified as US or Canada EPA legal are in tended for off road or marine applications only.  Products are NOT intended for use on emission controlled vehicles.

  • Mode 1:

    Green – Cruise Fuel Adjustment

Similar to adjusting pilot jet and mixture screw on carburetor vehicles. Decreasing the light value will add a lower amount of fuel. Increasing light value will add more fuel.

  • Mode 2:

    Yellow – Acceleration Fuel Adjustment

Similar to raising or lowering the needle on carburetor vehicles. Decreasing the light value will add a lower amount of fuel. Increasing light value will add more fuel.

  • Mode 3:

    Red – Full Throttle Fuel Adjustment

Similar to adjusting the main jet on carburetor vehicles. Decreasing the light value will add a lower amount of fuel. Increasing light value will add more fuel.

  • Mode 4:

    Green / Blue – Boost or Nitrous Fuel Adjustment

This function controls the amount of fuel added for boost and nitrous applications. Decreasing the light value will add a lower amount of fuel. Increasing light value will add more fuel.

  • Mode 5:

    Yellow / Blue – Acceleration Fuel Switch Point Adjustment

Decreasing the light value will cause the acceleration fuel to engage at a lower RPM. Increasing the light value will increase the RPM it engages.

TUNE THIS MODE WITH CAUTION!!!

  • Mode 6:

    Red / Blue – Full Throttle RPM Switch Point Adjustment

This function is the RPM switch point for when the full throttle fuel addition engages.

Adjustment is necessary to mostly match different pipes or big bore kits which require different fueling needs. Decreasing the light value will cause the full throttle fuel to engage at a lower RPM. Increasing the light value will increase the RPM it engages.

Instructions:

  1. Open hood and locate fuel rail, unplug the factor plugs off of injectors.
  2. Note on 2005 and older models: Plug the Boost Wurx connectors on to the injectors (green on the PTO and yellow on the mag); plug the factory injector plugs onto the Boost Wurx plugs (matching colors green with green and yellow with yellow).

    Note: If your snowmobile is a 2006 model you may see the Boost Wurx box showing a solid green light and flashing a red light, the sled sounds like it’s running on one cylinder, which means the box is not seeing an injector signal from one cylinder.  What we found is that Arctic Cat switched its signal wire on just the PTO side for 2006.  The easiest way to correct the problem is to switch the wires in the PTO side (Arctic Cat connector).

    Note: If your snowmobile is a 2007 or 2008-09, the wire in both (Arctic Cat connectors) will need to be switched around.

    Note: Looking at the front of the connector use a small pick tool and gently pry up on the pins locking device, at the same time pulling on the corresponding wire.

  3. Locate the blue connector on the air temp sensor, unplug the blue connector and plug into the white connector on the Boost Wurx box.
  4. Ground the black wire to a clean chassis ground.
  5. The white wire is for nitrous and is to be hooked up between the activation switch and the solenoid.
  6. Find a mounting location for the Boost Wurx box away from the heat and moisture.
  7. Use wire ties and secure all wires.
  8. Start the snowmobile.
  9. You should have scrolling green lights, followed by a solid green light.  This insures all connections are good.

Trouble Shooting

If you do not see the LED lights scroll or go solid green light, check all connections.  If the motor seems like it is running on one cylinder, call our tech line at 1-780-988-8726.

  1. Check your ground wire to insure that you have a good ground.
  2. Check all connectors and make sure the pins are properly seated and making good contact.
  3. Make sure no wires have become loose or have been rubbed through.
