I purchased the power tuner and the mid to high hit is a nice map up top but seems to be sluggish and jerky down bottom, anyone know what can be done to clean up the bottom end? Also what is the stock mapping so I can go back to that and see the true difference. Is it all zero's? Thanks in advance

On all the YZ's, stock mapping is simply to put a 0 in every setting block and upload that to the ECU.

My boy likes this map the best on his 15. Stock motor except fmf slip on only. I think it came from motocross action magazine but not positive.

Wonder if that map will be any different with stock exhaust?

We've ran that same map with stock exhaust with great results. Let me know how you like it.

I liked the "hard-packed" setting from the gytr website on my 14, 15 and 16 250f's.

What did you like better about it? My go to track has a little bit of everything and it's a bitch to dial in. Some turns are wet deep lumpy ruts and others are dry hard packed soft sweeping turns. I do
Like how the hard hit maps power is up top but bottom is choppy to me

It smooths out the powerband so its linear, for me the factory was too much off the bottom end. I like consistency all the way through.

How do you access engine time?
my tuner states error
cannot connect to ECU

everything is clean
Would older rechargable batteries cause this?
Any battery recommendations?
