Yamaha did a great job designing the new R-9. But how does it stand up to it's MT-09 brother on the Moore Mafia dyno. Follow along as this brand new bike gets it's ECU flashed.
What's up guys welcome back to the channel for those of you don't know my name is chris moore and today's video
We got a brand hammer new yamaha
R9 guys, this is our first time having one of these on the dyno
And for those of you who do not know
This is yamaha's I guess you would say kind of sort of replacement for the r6 the r6 is no longer made
They came out with the r9
Which is let's just say the mt09's cousin
This is the one with clothes on it. The mt09 is the naked version
And the looks and the appearance of this thing
Absolutely sick yamaha killed it with the looks on the new r9. I absolutely love it
I'm a big fan of mt09's to start with I really like that three-cylinder engine
They make really good torque really good power and they are very fun to ride
so
This one here
Yeah, it's pretty much got the same restrictions as an mt09
If you already have an r9 and you have ridden this thing, you know that first gear lagging second gear lagging a ton
They have less power in second gear than they have in first gear
We're going to talk more about that later, but let's get into dynoing this thing and seeing what it's got
In stock form and when I say stock form, I mean stock ecu with all the restrictions in place
Because this one
Has a brand new m4 full system
That is super super nice got the sound really really good on this thing
And it also has a sprint p08 air filter
Let's fire it up do our baseline pull. See what kind of numbers we got on our dyno
And let's start the tuning process boys
So
And our baseline numbers come in
About the same maybe actually. Yeah, definitely a little bit better than an mt09
113 67 foot pounds of torque
You can see how it goes up falls off and it kind of dies
So let's get to tuning this thing. See what we can get out of it
I'm going to show you the restrictions in the ecu as well
And just like that our ecu is being flashed using our woollett tracing tuning software
We are about to hook this r9 up now
Let me show you a little something on this computer while the other computer is flashing
This right here is a stock map and we are in the etv table
So that stands for electronic throttle valve. You see we got it in mode one
Which is our fastest and we got it in gear one now these numbers up here at the top
This is our throttle position sensor. That's what our hand is doing
So this is when you go wide open with your hand
This is our table that we're running in and then this over here is our rpm table
Take a look at this guy. So first gear
This is supposed to be our fun gear where we do all our wheelies all our nonsense
Check this out. So you go wide open throttle with your hand
the bike goes at
4500
41 throttle
Let's just scroll down here. We go to
6500 rpms
You're getting 63 throttle. So you're pinned but the bike
About right there
63 and then you can see how it never really continues to go much higher goes to 85
But then back at 10 one
She's shutting back down on you to 81
Now let's just take a look at this. I'm going to highlight a few things
We're at
3500 rpms
We're at a hundred through let's just go to 60 now. We're going to go to 5000 rpms
All right, there's our numbers you see we're in the high 30s
To 40 now, we're going to switch her over into second gear and
geez
Second gear now we're getting less power
What?
Let's go to third gear boom jumps up to 50 throttle
so
Long story short why in the world yamaha wanted to neuter second gear so bad. I have no clue
But long story short you already got an r9 you already feel that you go from first
second
third
Why would it be that way total nonsense anyways, we're gonna fix all that stuff today
We're gonna make first gear come to life second gear come to life third gear. We're making them all come to life
Let me show you something else another thing too. You can see in our dyno graph
We dyno the thing in the fifth gear. I forgot to show you all this
You can see it does finally go a hundred percent throttle in fifth gear
About let's see. Where's that at seven thousand rpms stays a hundred percent to ten thousand
And then you can see shuts back down again at eighty percent throttle
Same thing in six. So that's also limiting and holding back our top speed. We're going to get rid of all that
We're going to flash the ecu. We're going to lower the fan temps
We're going to do all the good stuff that needs to be done right here today. Watch this
Ecu is flashed restrictions are gone. We're going to dial in the fuel run the fuel two
After we run this baseline full with the restrictions y'all. Let's see what we got
So
Two pulls back to back both of them
116 horsepower and 69 foot pounds of torque you can see how our power picks up a little bit everywhere
But the biggest thing is it continues to carry out much much farther
Let me dial in this fuel. Our air fuel ratio is not horrible already
So we're going to dial that in from here and get her perfected
So
It's safe to say that the yamaha r9 responded very nicely to the tuning
Let me show you the before and after numbers here in just a second guys
Guys, so we simplified this thing got the dyno sheets where you can see it. We started at 113
We finished at 120 71 foot pounds of torque
The gains are very nice
All the way as soon as you hit the gas and then you can see at ten thousand one hundred rpms
We went from 108 to 119
So super nice gains
Mt09 i've done a couple 2025s on the dyno with full exhaust systems
I don't think they had m4 exhaust systems, but they only made around
116 117
So that's where i'm calling on you the professionals of youtube
Comment in the comments below. Let me know. What's the difference in the engine slash airbox slash transmission slash
sprocket slash
Ecu you tell me what's the difference between an mt09 and r9 guys
