Market analysis
How much does a used Infiniti QX80 engine computer cost?
Asking prices for a used Infiniti QX80 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. Condition matters: grade-A units (lowest mileage, best condition) carry roughly a 96% premium over grade-C stock, with grade-A medians at $147.
Model year matters too: 2018 units carry the lowest median at $122, while 2025 tops the table at $500. Parts from 2016–2020 are interchangeable, so if the 2018 fits your vehicle, it offers the best value across 5 compatible years.
Against comparable vehicles, the Infiniti QX80 sits 26% above the Honda Accord ($112), 27% above the Honda Civic ($111), and 12% 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.
