I failed to read and write Fiat Marelli MJD 6JF ECU with your new KT200 (KTM200) ecu programmer (the same as foxflash) on bench. Wiring is the same as the document. How to fix it?Images attached:
KT200 will read and write Marelli 6f3 full system, read eeprom too.
You can also read and write via OBD if there are VR files available. But bench mode is faster than OBD VR reading.
