three generations of ECU, 1) Rocket 3 Std / Classic, 2) Rocket 3 Roadsters 2010-2012 and some very early 2013, 3) Rocket 3 Roadster since then, none locked as yet
I forgot there is also the Rocket 3 Touring 2008 onwards, so that makes 4 generations/versions of ECU
Also not to be confused withe the Tourer which was a dressed up Std (generation 1 ECU)
