Hi All,

I installed a new FMF exhaust, comp ECU and short throttle stop screw. I found the Yamaha maps for FMF, as well as some Aussie maps, but everything is labeled for 12-13 models.

Anyone know if the 14 will have issues with these? Did anything change on the 14+ models that would cause problems?

I live in Phoenix, so going to try the Aussie map I found first.

Thanks much!

The maps are also applicable to the '12 thru '15 models...and you need the competition ECU.


Other than the color of the plastics nothing much has changed.
