About Engine ECUs / ECU / ECM
The engine ECU (ECU / ECM) is the electronic control unit that controls your vehicle's fuel injection, ignition and engine management. In ECUALL’s catalog you can find engine ECUs made by Bosch, Siemens/Continental, Delphi, Magneti Marelli, Hitachi and Visteon by part number.To choose the right engine ECU, compare the hardware (HW) and part numbers on the label of your vehicle's ECU with the numbers on the product page. If you're not sure, send us a photo of the label via WhatsApp and we'll check compatibility for you.Frequently asked questionsWill the vehicle start right away after replacing the engine ECU?In most vehicles, the engine ECU works paired with the immobilizer system. As a result, pairing, coding or cloning may be required after replacement. With an ECU that has the same part number, these procedures are carried out without issues.What is the difference between a used and a new engine ECU?A used ECU is an original unit that has been used in a vehicle and then inspected. It is much more affordable than a new ECU. All used ECUs at ECUALL come with a 6-month warranty.Which numbers need to match for an ECU to fit?The ECU manufacturer's hardware number (e.g. Bosch 0281…) and the vehicle manufacturer's part number must both match.
