Used Porsche ECU / DME Engine Control Module, OEM number 99661860500 — a genuine used part removed from a donor vehicle. This engine computer manages ignition, fuel delivery, and timing on 996- and 986-chassis cars with 2.7–3.6L flat-six engines (both naturally aspirated and turbo). When the DME fails, common symptoms include stalling, no-start, rough idle, or a check engine light for communication faults. This unit requires coding to your vehicle’s VIN upon installation by a qualified shop or dealer.
