First off how do you like it you lucky dog? I wen't to a Yamaha update clinic a few weeks ago, it is my understanding that they were going to make maps available to accompany the GYTR products. I have the tool but NO BIKE to try it on. I would be a little careful until some more info is available, the guy doing the class said Yamaha allowed it to do a lot more than he thought should have been available to the public.

I too would wait until some more people have these in their hands. I have my Tuner, but no bike. I would keep it stock until more infor is available.

Lucky maybe but i pay 9000e around 13000usd have some humor on that! You guys are so good in us to have parts and bikes so cheap least they looks cheap to us here in

europe. Anyway bike is mega but not so much hype what they been talking 250f is still

lot lighter than this new 450 but still its great motorcycle for sure. That i was thinking too to wait get somemore info whit EFI.

This is interesting and a little suprising. How exactly does the Yamaha tuner compare to what you can do with the kawi, honda or power commander tuners?

The difference is that it's actually intuitive in comparison. No need to send out your ECU like on other bikes. i.e. Dummy Proof.

Mabe we should start a new sticky thread so we can share maps easily.

It would be good to try maps by other racers to compare.I have had the tuner for while now( still no bike, next week i am told.) and it is very easy to use.

I cant wait to use the diagnostic capabilities of the tuner also.:excuseme:

Never used or seen the Kawi or Honda and the Power Commander requires a computer unless they have a hand held I don't know about. The Yamaha lets you re-map as well as letting you see a live reading on the sensors. Looks to be easy to use.

The yamaha tuning system looks great. Makes the other systems look old and outdated already! Who wants to carry around a laptop and battery to make changes? Yamaha system is way less complicated.

I like that it doesn't require a computer, but was just surprised to read that a Yamaha rep said "Yamaha allowed it to do a lot more than he thought should have been available to the public."

My question is more along the lines of what all can you change (or not change) with the Yamaha tuner that can't been done with the other systems already out. I'm no expert, but it looks like there are less changes that can be made with the Yamaha tuner, which may or may not be a bad thing. If it is, I am betting someone will come up with a way to make even more adjustments to further dial the bike in.

and probably not needed. MXA, went through something like 17 maps when testing on the Honda and ended back with stock. You don't want or need to get carried away with changes as it works pretty well out of the box. Yamaha seems to have made it very easy to do at the track, however.

Makes sense. Going back and looking at the info gray posted it looks like you can make adjustments for low throttle, mid throttle, and full throttle and then low speed, mid speed, and full speed for each of those.

My only personal experience with this type of thing is with the power commander which you can make adjustments every 500 rpm from idle to redline and then with 8-9 different throttle positions for each of those. On a bike that redlines at 13k that would be around 20 x 8 values you can adjust versus the 3 x 3 of the Yamaha tuner.

How do the Kawi and Honda controllers compare?

its a much better and cheaper system than honda ,kawi or suzuki if you under stand jetting and know how you like your power delivered and where you need to change the delivery of it then all you need to do is make small changes at a time till you get the result you want

How is it "much better", that's what I'm trying to figure out. I'm more looking for the actual differences between the variables that can be adjusted between this and the other available systems. I'm just a little surprised you can only adjust for low, mid, and full throttle and speed variables. Are the race teams going to use the Yamaha tuner or will they use something more advanced?

I would say you would have to use the tuner if you replaced the stock exhaust with an aftermarket one like FMF ,yoshimura,DRD just to name a few.

You would probally have to use the tuner to adjust the leanness or richichness of the fuel/air mixter pending which pipe you put on and how it is effecting the bike. Thats just how I would see it.

The manual that rickk posted up said in their that one could check the running time on the motor.

So I guess there would not be any need for an hour meter if you can check and see how many hours of running time there is on the bike through this power tuner.

Here's the entire EFI Manual. Man, that's easy to use.

Yeah! it is easy to use............but kinda of frustrating to understand on what settings to make.

You would think they would have had aftermarket pipes or air filters downloaded in this powertuner so when you made an aftermarket change to the bike...... example (put on a BIG GUN exhaust or pro circit exhaust or a twin-air filter or combination of both)

They would have a map already set for these changes so all you had to do is find what changes or mods you have done to the bike and click on them and your set.

to me this power tuner will be kind of cantankerious. If one is not careful you could burn the piston up by advanceing the timing to much or throw the fuel curve off as much into thinking the bike is starving for fuel and there the bog would be back.

correct me if I'm wrong but this PT will seem to be a valuable tool it is just understanding it first.
