Description
OEM part numbers RF2A18701A and 131000-1022. Mazda 323F engine ECU control module — genuine used, tested original equipment.
The engine control module (ECM/ECU) is the primary management computer for the engine. It processes inputs from the MAF/MAP sensor, throttle position, coolant temperature, oxygen sensors and crank position sensor to control fuel injection timing and duration, ignition timing, idle speed, turbo boost (where fitted), EGR and emission systems. The ECU maps are calibrated to the specific vehicle and engine variant.
Engine not starting or struggling to start, engine running rough or misfiring, poor performance, excessive fuel consumption, engine warning light (MIL), limp mode engaged, idle instability or stalling.
Good used condition. Match BOTH OEM numbers to your vehicle before ordering — ECU variants are VIN/engine-code-specific. Professional installation and coding/immobiliser adaptation is required. On most vehicles the ECU must be matched to the vehicle’s immobiliser (key transponder) by a specialist. 14-day returns on unmodified parts.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
