Tried doing a variety of searches and also read thru the EFI sticky but could not find anything specific for the 2015 YZ450.  My bike is 100% stock and I am looking to experiment with maps to broaden the low to mid transition without affecting (or even increasing over-rev)and allow 2nd and 3rd gear to pull a little farther.  Personally I think the roll on power is pretty good (not barky).  I only ride MX at the vet B level on east coast tracks which are mostly fairly fast tracks but usually end up pretty rutted on race day so cornering is very important.  I have found one map recommended from Dirt Rider which leans out the fuel and advances the ignition that I plan to try but if anyone has some real world experience with different maps specific to a stock 2015 YZ450 I would certainly appreciate it.

This is a mxa map that is very smooth. Has a very consistent feel that pulls well into the over rev. Does not have a big hit on the bottom end.

I'm currently cunning the map in the middle with a full Dr. D and the thing barks. It pulls super hard on the bottom. Not sure how it will work with the stock exhaust.

That's about all the info I got. Hope some of it is useful for you

Thanks.  Is your bike 2014 or 2015?

"Zero" mapping for the 14 and the 15 are different.  Mapping for one doesn't apply to the other.

Yep, thats why I asked what year bike.  So back to the original post, any insight for maps on the 2015 YZ450?

The following link has suggested maps for the 15 YZ450f under the Specifications tab.

Thanks.  I have looked at that site 10 times and never realized you could scroll down in that window...  


The Dirt Rider map is identical to the first one (Hard hitting/Loamy condition).  I loaded that one and initially thought it was actually smoother than the stock off the bottom but with better roll-on as you transition into the mid.  Thought it was better on starts (dirt starts) too.  


I plan to try the longer pulling/sand condition map on my next ride which is a sand track.

I just picked up a used 15 and am surprised by the lack of maps for this year. Is the factory map that good for both stock and aftermarket exhausts? I plan on trying the 3 maps on Yamaha's website but from what I can tell they are only for the stock exhaust. Anyone have useful maps to share for their 15?
