Where the Infiniti Q50 engine computer is listed

Market analysis
How much does a used Infiniti Q50 engine computer cost?
Asking prices for a used Infiniti Q50 engine computer are unusually spread out: the top listing asks more than ten times what the cheapest does, so which unit you pick matters more than the median.
Fitment variant moves the price more than most buyers expect. The most affordable variant we track, Electronic Control Module, 3.0L, (VR30DDTT), lists at a $115 median, while Electronic Control Module, 2.0L commands $146, a 27% gap inside the same part category. Confirm which variant your VIN requires before comparing quotes.
Model year matters too: 2016 units carry the lowest median at $108, while 2023 tops the table at $330. Parts from 2014–2018 are interchangeable, so if the 2016 fits your vehicle, it offers the best value across 5 compatible years.
Against comparable vehicles, the Infiniti Q50 sits 25% above the Honda Accord ($112), 26% above the Honda Civic ($111), and 11% above the Hyundai Elantra ($126) for the same part. The “similar vehicles” cards below open each comparison guide.
Buying a used engine computer: what to check
- Match hardware and service numbers: Ensure hardware revision codes and circuit board part numbers match exactly, as pinouts change mid-model year.
- Inspect multi-pin connector headers: Check header pins for bending, green copper oxidation, or burnt circuit board traces inside the wiring sockets.
- Verify immobilizer programming requirements: Plan for anti-theft security relearn procedures or ECU re-flashing before the replacement computer will start the engine.
- Confirm donor transmission and emissions spec: Ensure the donor vehicle used the same transmission type and regional emissions package to prevent fault codes.
- Check aluminum casing seals: Inspect housing screws and perimeter rubber gaskets for white oxidation or breaks that indicate past water intrusion.
