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.
This model is ONLY for machines that have an ECU connector with 3-rows of pins. Non-North American machines from 2014-2015 have the older style ECU connector with 2-rows of pins. If your ECU connector has 2-rows of pins, see ECU-SUZ-750-2I-UT.
