Replacing a faulty Engine Control Unit (ECU) in your FCA vehicle can be straightforward with ECU cloning. This process allows you to transfer the original ECU’s data to a new or used replacement, creating a plug-and-play solution. Ecu Hero Gpec simplifies this procedure, eliminating the need for dealer intervention or additional security information.
This guide outlines how to clone common FCA ECUs using the ECU Hero GPEC system. Supported ECUs include: GPEC3, GPEC2A, GPEC2, GPEC, NGC4A, and NGC4.
ECU Cloning Process with ECU Hero GPEC
ECU cloning with ECU Hero GPEC involves these key steps:
1. Identifying the Original ECU
Begin by identifying the original ECU’s part number and operating system (OS). Also, note the Vehicle Identification Number (VIN) and Software Release Index (SRI), if applicable.
2. Reading and Saving the EEPROM (If Supported)
For ECUs that support EEPROM reading (GPEC2A, GPEC2, GPEC3), connect the original ECU to ECU Hero GPEC and read the EEPROM data. Save this file to your computer. GPEC and NGC4 do not utilize EEPROM.
3. Writing the EEPROM to the Replacement ECU (If Supported)
Connect the replacement ECU to ECU Hero GPEC. If the ECU uses EEPROM, select the “Write EEPROM” option and choose the original EEPROM file you saved earlier.
4. Flashing the Replacement ECU
Select “Flash Memory” and choose the correct hardware/OS file corresponding to the replacement ECU’s part number. This step is crucial for proper functionality.
5. Verification
After flashing, verify that the VIN and SRI of the replacement ECU match the original ECU’s information. This confirms a successful clone.
Important Considerations for ECU Hero GPEC
- GPEC ECUs: These modules require only VIN setting and the correct hardware/OS file for flashing.
- NGC4 ECUs: Instead of EEPROM, these units require reading and writing security bytes.
- Token Usage: Each ECU (original and replacement) requires one Hero token for licensing, totaling two tokens per cloning procedure.
ECU Hero GPEC simplifies the ECU replacement process for compatible FCA vehicles. By following these steps, you can efficiently clone your ECU and get your vehicle back on the road.
