33920-66K21 / 33920-66K22 / F192-I41 Engine Control Unit (ECU) Suzuki Cervo K6A.
The Engine Control Unit / ECU with OEM/reference numbers 33920-66K21, 33920-66K22, and FI92-141 is a factory-type ECU for the Suzuki Cervo (such as HG21S or similar models) equipped with the K6A (≈ 660 cc kei-class) engine. This electronic module monitors and controls essential engine functions: fuel injection, ignition timing, air/fuel mixture, throttle control (if present), emissions regulation, sensor diagnostics, and on-board diagnostics (OBD).
Units are most often offered in used / tested OEM condition. Before replacement, one should:
Confirm that the ECU number on your original unit matches one of the above (or a known compatible variant)
Check connector pin count / layout to ensure plug compatibility
Ensure immobilizer / key code compatibility — many ECUs are locked to VIN or have security coding
In many cases, the ECU will require programming / cloning / adaptation so it works correctly in your vehicle (VIN transfer, security data, calibration)
For example, BE FORWARD lists a used ECU with those exact numbers (33920-66K21 / 33920-66K22) for a Suzuki Cervo (CBA-HG21S) model.
