Wildcat XX ECU Programming 

These programs have been in the works for some time now, and we're finally ready to let the cat out of the bag! They have some cool features many have been looking for, most notably the Raised Speed and Rev Limiters in addition to the added Power and Performance without the need for a separate fuel controller. Another unique feature is the optional Multi-Map Pedal Tune that enables you to dial in the drive by wire pedal response for different riding conditions. Using the same technology as our popular and proven programs for the Arctic Cat 9000 Series Snowmobiles, we also have Flash Tools available for Dealers and Performance Shops to program machines on the spot via the factory diagnostic port so there's no risk of damage from cracking the ECU open or addtional wait time shipping. As always, any consumer or dealer can send the ECU directly to Speedwerx for programming- we typically program and ship within one business day for minimal downtime as well.

Standard Features For All Programs:

  • Reworked Fuel and Ignition Tables for Added Power and Performance using 91 Octane Pump Fuel
  • Horsepower Increased Over Stock (up to 7 whp when combined with slip-on exhaust). 
  • Rev Limiter Raised to 9800
  • Speed Limiter Raised to 120 MPH
  • Left Foot Braking enabled so you can operate the throttle and brake at the same time without going into limp mode
  • Race Start feature enables you to start in gear without pushing the brake
  • Cooling Fan Activation temps lowered 15° for a cooler running engine
  • Drive By Wire Pedal Map revised for more aggressive throttle response
  • Faster Starting for race applications with engine-off starts
  • Diagnostic Port Flash - your ECU does not have to be opened up or even removed from the machine! 

Additional Multi-Map Pedal Tune Features:

  • Dash Flash for the Digital Gauge Cluster enables Multi-Map Pedal Tunes
  • Choose between three pre-set Pedal Tunes for different riding conditions- M1 VERY aggressive (drag racing), M2 linear (duning, general trail riding) and M3 fine (rock crawling)
  • Vehicle Speed Limiter can be set via the dash. This would allow younger or less experienced drivers use the vehicle more safely. The speed limit can be pin protected for added safety!
  • Adjustable Gauge Cluster Backlight Dimmer- a must-have for night riding!

NOTE: If you have purchased our ECU Programming and wish to make a change, Stage 1-3 programs may be changed to a different Stage 1-3 for $50, or upgraded to the Stage 3R for $100. Any Single Stage program may also be upgraded to the Multi-Map Pedal Tune version for $300. 

You must send your ECU box (and Digital Gauge Cluster if purchasing the Multi-Map) to us for programing! Please include a copy of your invoice or a note with your return address and order number. Your ECU and Gauge will typically be re-mapped and shipped within one business day for minimal downtime- the return shipping cost for the service of your choice will be added when purchasing online.
