Does the GTYR ecu come with map choices and instructions? or do the maps come with the $250 tuner or a site download from somewhere. Im just trying to get an idea how this would work if I dive in.
I noticed all the 2015 Yz bikes alread have GTYR stickers, so I guess the GTYR is standard issue on those. Im still waiting to see a 2015 WR450, and don't know what the hold up is but 2 shops in my area have none.
No, the GYTR
ECU does not come with maps, you have to either buy the tuner or borrow someone else's tuner to make fuel and ignition changes. If I'm not mistaken, the tuner comes with a few maps but I'm also willing to guess there's a reasonable amount of user developed data out there in cyber land just waiting to be snatched up by the intrepid GYTR tuner if so desired.
GYTR is simply an acronym for Genuine Yamaha
Technology Racing. Anything Yamaha
can be GYTR not just the ECU or tuner etc.. For instance, my bike has the GYTR muffler insert and the GYTR ECU. My guess is that the MX racing peeps must be, according to Yamaha sales information, more into having "race" stickers on their bikes. And let's face it, the MX bikes are probably more "full on" than these bikes so it kinda makes sense.
For the record, I just ordered my own tuner. I want full control over my mapping. I don't want to have to trust someone else's maps unless it comes from Yamaha.
