ECU, also known as electronic control unit, is an important part of automobile engine control system. It can adjust the parameters of the engine in the working process to achieve the purpose of saving fuel and reducing emissions. Refreshing ECU can improve the performance of automobile by updating ECU program or adjusting ECU parameters. 1. Collect the ECU program to be updated and the adjusted parameters. To refresh the ECU, we must first collect the relevant information needed for the refresh, including the ECU program to be updated and the adjusted parameters. This information can be collected on the official website of the automobile manufacturer, or consult the technical service hotline of the automobile manufacturer to inquire about the updated ECU program and parameters.

2. Prepare to brush ecu software and professional ECU scanner. Updating ecu needs to use professional ECU scanner and corresponding brush ECU software. Therefore, before refreshing the ecu, it is necessary to prepare effective professional scanners and ECU software to ensure that the ECU update can be completed smoothly.

3. Connect ecu and computer, install software, and prepare to update ECU parameters. Connect the ecu scanner to the computer, then install the ecu software, initialize the parameters, read the original program and parameters of the ecu, compare the effective parameters of the ECU software with the original parameters of the ECU, and prepare to update the ECU parameters.

4. Update the ecu program and record the parameters. After completing the previous work, according to the operation instruction of ecu software, update the parameters of ecu software to ecu, start the ecu burning program, burn the parameters to ecu, and complete the update of ecu program.

5. Check the update of ecu program. Finally, check the update on the ecu to ensure that the parameters are updated correctly, and check the working condition of the engine to ensure its normal work. If any abnormality is found, the ecu parameters should be modified or the ecu program should be refreshed in time to ensure the success of the update.

The above is a tutorial about automobile brush ecu. If you want to refresh the ecu, you can follow the above steps to ensure that the refresh is safe and efficient.
