What's wrong with it?
It should either work or not work at all.
Unless they adjusted the air/fuel map...which should never be done without a datalogger or dyno.
If you need an ecu, a 2008 -2016 will work.
The only difference in years is the addition of ABS in 2013, and it has it's own controller. No changes to the ecu.
If the bike still runs, then the engine is likely ok, the ecu just needs flashed correctly.
I'll flash it for free if you send it to me, or are within riding distance of south central VA.
I've flashed a couple dozen with zero issues. I generally don't advertise for it, as they're all freebies.
I don't want to compete with the site sponsors, but there's no sense in paying again to have it done right.
