Code 39 on Ecu -00

contact@fb-racing.fr

Hello, I wanted to flash a customer's ECU 13S-8591A-00. During the first connection, the reading of the initial file was blocked at the end of the process and I failed to read it. So I flashed 13S-8591A-20 directly for use on a Us harness and had a code 39 (open circuit on primary injectors), the engine does not start. My beam tests are ok and the machine started before the flash. All the US type files tested gave me a code 39 and no fuel injection, the EU files gave me no fault but did require a transponder (deleted) and therefore did not interest me. With a different US type Ecu on the same harness, the engine starts well and flawlessly. Thank you in advance for your return.

You cannot flash a US file onto a Euro harness because the firing order of the fuel injectors and the primary coils is different, that is why you were getting that error code.
