Swapping '13 ecu for a '12 will most likely cause a huge headache that you don't want to deal with and there will NOT be a positive difference since the '13+ models have s+ buttons, better Li - ion batteries, and gearing ratios are different I believe for MT.

Now my question is why would you possibly want to do this?

The 12 ECU is Hondata compatible for the JRSC, that's one thing....

But I agree unlikely to work, and likely to cause major headaches.

It is hard to say whether an ECU swap is feasible or not... If Helm would come out with a service manual for the 2013+ models already, then we could at least see if the pinouts are the same. I don't think they can be THAT different from each other, since all of the same basic stuff is there. The differences in the ECUs might just be about small details, like the final drives being different and such...
