Hello,
I have two MSV80 ECU's and want to clone the one with bad HW to the other.

I have not used the cloning feature yet as I just got it activated. I was hoping to use SERVICE mode but the wiring info mentioned that you have to add a resistor and CAN transceiver for service mode and the transceiver is out of stock at most places.

Is this transceiver required only for SERVICE mode or also for BOOT MODE and OBD-2 MODE? It's not clear to me as I see the same connections made to CAN1 and CAN2 in all cases, but I also see that there's already one CAN chip on the board.

I tried to connect to the ECU in SERVICE mode and PBD-2 mode without any connections to CAN2 (just to see what would happen) and I get a message saying "cant read VIN".

I'm wondering what method I can use to successfully clone the ECU without needing to add a CAN chip. Will BOOT MODE work? I didn't try it yet.

you can try to read it on factory mode first, if any error like no communication then you need to open and check if the components are missing. If yes need to add that them make backup from original and donor then connect original and click on CLONE button. Please check the attached video as reference .

Thanks. I had to give up on this as the 2551 CAN transceivers are not available anywhere right now!

.. don’t give up mate _ you have two MSV80’s both with 1 CAN transceiver each, borrow from one and continue with the process. Don’t forget the 2K ohm resistor and the CHOCK those you can get from any HSCAN driven modules

If you got autohex you can read ISN from donor ECU and write to CAS. Then do coding for DME to adapt VIN from CAS.
