Description
This service will clone one SIMOS ECU (source) into another SIMOS ECU (donor).
Requirements:
- ✅ Checksums are calculated automatically
- ⚠️ Full bench/boot readouts are required
- ⚠️ Both ECUs must use the same WFS generation
- ⚠️ ECUs with WFS5SWS_SHE are NOT supported
- ⚠️ Both ECUs must be hardware compatible
- ⚠️ MCU ID might be required for some SIMOS ECUs → FAQ
- Wrong MCU ID will result in an unusable file!
- ℹ️ Supported file sizes → FAQ
Supported ECUs:
PCR2.1, SIMOS 8.1x, SIMOS 8.2x, SIMOS 8.3x, SIMOS 8.4x, SIMOS 8.5x, SIMOS 8.6x, SIMOS 10.x, SIMOS 11.x, SIMOS 12.x, SIMOS 18.x
ECUs with WFS5SWS_SHE generation don’t contain full immodata in the dump, these can’t be cloned/transfered. In such case recommended solution is immo-off + VIN change.
How to use the service:
- Read both SIMOS ECU full dumps in boot/bench
- Upload both SIMOS ECU dumps
- Process dumps
- Service will tell you if ECUs can be cloned
- Download processed file(s)
- Write downloaded file(s) to donor SIMOS ECU
