Which is the quickest tool for flashing the med9? 12 minutes is a bit slow with the usual suspects..

MPPS v13 seems quickest for me. It'll do it in about 9 mins. v16, v18, Kess and FGTech all take 12-15mins.

Failing that, it's BDM. I've got a development ECU that I soldered a cable on and was going to install in my Mk6 R but never bothered getting round to it. 9 mins is sufficiently quick enough that I'll put up with it and if I've got a file to flash, I've usually got something else I can do while its writing.

Its just a shame mPPS v13 doesn't skip the blocks which aren't changed like it does with ME7 ecus. 

It is possible to flash it just as fast as every other ME9/MED9 ECU. But I already said what the pre-req for that is.
For example the cal area on the GM/SAAB ME9 flashes in about a minute and a half.
The MB ME9 flashes in 40-50 seconds.

The thing with the BDM is that you have to disconnect the connector every time. You can't BDM it with the connector attached.
Still a lot quicker than OBD flashing, especially if you are working with a dual MED9 car.
