The Copperhead® ECU is a plug and play replacement for the stock ECU in the King Quad 750 EFI. It controls the timing and fuel, and eliminates the low speed lag and heating issues. It provides a typical 21% power increase from idle to redline (WOT), and a part throttle power increase of up to 40%. NOTE: THE KQ750 UNIT IS PHYSICALLY THE SAME AS THE KQ700/AC700 UNIT, IT IS JUST LOADED WITH DIFFERENT FIRMWARE.

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 the USB Memory Interface (sold separately).
