🚀 WHY ECUCAR

ECU compatibility information can be difficult to find across different technical sources. EcuCar brings vehicle, ECU and MCU reference information together in one simple app, helping you find relevant information faster.

⚠️ IMPORTANT

EcuCar is a reference and lookup database. It does not connect to your vehicle, scan your ECU, read live vehicle data, program an ECU, or clear diagnostic trouble codes. OBD, CAN bus and other technical information shown in the app is reference information only. An internet connection is required for cloud database results.
