Restore peak performance and throttle response to your fuel-injected GY6 with the Universal Parts Replacement ECU. Specifically mapped for the larger displacement "200cc" (161QMK) EFI engines, this unit ensures optimal air-fuel ratios and ignition timing across the entire powerband.
This ECU is a confirmed fit for most 161QMK / QMK161 4-stroke "200cc" EFI engines found in the following models, and many other 170cc-250cc EFI GY6 scooters.
Mechanic's Note: When replacing an ECU, we highly recommend checking your spark plug color after the first 50 miles. If the engine is still running lean, inspect your fuel injector and O2 sensor for proper operation, as this ECU relies on clean sensor data to manage the fuel map.
