A used Acura RDX engine computer carries a median asking price of $167, which is 19% higher than the Kia Soul at $136. Supply also plays a role: Kia Soul has 3,434 priced listings versus 488 for Acura RDX, and more listings generally mean more choices and more competitive pricing.
The Kia Soul average ($156) runs 15% above its median ($136), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 10 model years for the Kia Soul (2015–2025) but only 3 for the Acura RDX (2017–2024), so the Kia Soul data reflects a broader range of generations.
The Kia Soul engine computer is interchangeable across 12 model years versus just 4 for the Acura RDX — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade B (good) condition, the Kia Soul is 39% cheaper ($125 vs $206) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used engine computer
- Match the hardware part number and catch code exactly, as internal board architecture varies even within the same vehicle year and engine family.
- Confirm security anti-theft (PATS, PASS-Key, or Immobilizer) pairing requirements, as used ECMs almost always require VIN programming before starting the vehicle.
- Inspect connector headers for bent pins, thermal discoloration, or green corrosion indicating water leakage through the wiring harness plug.
- Verify emission tier compatibility (Federal/EPA vs. California CARB standards) and transmission control integration (PCM vs standalone ECM/TCM).
