The Copperhead® ECU is a plug and play replacement (not a piggyback solution) for the stock ECU in the Suzuki King Quad 750. It controls the timing and fuel, and our high energy and repetitive fire ignition allows for crisper throttle response, reduced fuel consumption, while giving substantial power gains.

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.
