2006-2009 Arctic Cat 700 EFI (not for H1) Copperhead® ECU

The Copperhead® ECU provides a typical 21% power increase from idle to red-line (WOT), and a part throttle power increase of up to 40% over stock. In addition, the top speed limiter has been increased. The ECU also allows for the fuel to be adjusted for aftermarket camshafts and pipes (requires optional programmer interface). Comes complete with the Copperhead® ECU and a machine specific adapter harness containing the EFI specific electronics and mating connectors for that model. 

For increased power, the injector from the Suzuki M109R Boulevard Cruiser can be installed (Suzuki SKU 15710-48G00). This injector has 12-nozzle holes to give substantially better atomization. This results in approximately 25% more part throttle power over the stock injector. 

NOTE: Due to it's larger size, some machines may have harder starting, and more bottom end lag. We recommend purchasing our programming interface to adjust the maps to address these issues. 

Features:

• Repetitive fire ignition delivers hotter spark with longer spark duration for maximum power and virtually eliminates misfires, while giving you easy starts and crisp throttle response. Preloaded performance map allows the machine to run cooler, produce more horsepower and more torque, while minimizing fuel consumption.
• Shipped with machine specific harness that plugs directly into factory wiring harness. Toggle switch on the unit allows user to switch between two preloaded setups.
• Default preloaded map keeps factory limiters (reverse / speed) and similar power when the toggle switch is in position #1. When the toggle switch is in position #2, all limiters are disabled, and the timing is optimized for maximum power on 87 octane fuel. Setups and maps can be changed and optimized for different fuel grades via our programming interfaces (sold separately).
