5-step workflow
- Read out your ECU bin file via OBD or bench (KESS3, AutoTuner, MPPS, Trasdata, Flex, FRF flasher).
- Open Softechpro V5 and drop the .bin / .ori / .hex / .s19 / .frf onto the workspace. Softechpro auto-identifies the ECU family from the header signature.
- Select Start-Stop OFF from the service tab.
- Hit Save patched .bin. The ECU-specific checksum is recomputed automatically.
- Flash the patched file back via your existing flasher. Reset adaptations via the OEM scan tool if required.

Frequently asked questions
Can I re-enable start-stop later?
Yes. Flashing back the original backup .bin restores factory start-stop behavior immediately.
