It's impossible to flash later MED17 ECU's OBD, so yes they do all need flashing on the bench. The chinese tools that do this are a joke. I managed to recover one ECU with a genuine tool, but the other two were cooked..

I was on the phone with both SCT and Cobb yesterday, and both told me that *most* MED17.5 ECU cars are tunable via the OBD2 port. Ford's 2013 Focus ST for example, can be tuned just by updating the firmware on an SCT XCal3 or 3015.
However, for whatever reason it may be; I will probably never be able to port flash this particular ECU in my 2013 Golf. So, the next questions are:
-Which tools should I buy?
-What software will be capable of reading and writing to my particular MED17.5?
-Is finding, interpreting and editing maps any easier than it used to be? Or is it back to HEX-edit with these ECUs?
-Is there a good walkthrough for an experienced DIY tuner new to the MED17.5 ECU, and new to Nefarious Motorsports?
