Touring/Sport modes ?

[fraserdog]

What exactly does the Touring/Sport mode alter? There seems to be such a dramatic difference on my bike between the 2 modes it's like the Touring mode keeps the engine at a lower BHP and the Sport mode gives the bike the full BHP,i say this as my 955i Tiger (105BHP) seems like it would run rings around the XT if it were in Touring mode.

There is a huge difference between the two modes, I was surprised at how soft T is but S is very snatchy, I've only just mastered riding in S mode without the bike lurching about. The ECU softens the power delivery in T to stop the wheel spinning up if it's slippery but when up to speed you should find the power much the same. I used t when running the bike in but if you need to react quickly to something T can be too soft. If you have a remap or fit a power commander you can alter the characteristic of both modes.

It almost feels as if it needs another mode between the T ands S as they are so different.

I'd agree with that.

The modes change the rate that the throttle bodies open, HP is the same.

AVC8130 is a member who does remapping and has spent little time here since his second child was born a couple of years ago. We discussed the maps quite a bit once and . . .


T mode in the Gen1 ECU gives about 2/3 full throttle so you get less throttle response per degree of rotation. Not sure if this stayed the same in Gen2 so am not differing with Fred here. In both generations there is more of a gradual off-idle transition. In the Gen1 bikes the first 3 gears had additional restrictions, but this seems to have been removed or reduced for the Gen2 bikes.


Sport mode has very little of the off-idle transition and is nearly straight response from idle to 100% throttle.


If you have a steady hand they should each give you the same mpg for a given speed, the difference is how they get to that speed.

Hi Bob,

I'm not sure if AVC was talking about all gears vs the restricted 1-3 gears in his discussion with you of 2'3rd throttle body openings. I do know that Yamaha's dealer training on both Gen 1 and Gen 2 bikes say that power is not reduced, only throttle response. This dyno chart published by Motorcycle Consumer News on the Gen 2 shows that max HP is the same, and they even got a little more in T mode.

Hi Fred -


Obviously, there are multiple sources of info out there. AVC8130 was writing about Gen1 bikes when he wrote the following and it's the same we discussed in person a couple of years ago:

As far as ride-ability, NOTHING will do as much per dollar as flashing the ECU. My service, Diapson, ECU-U. It's your choice.
Yamaha did us no favors with the factory throttle mapping.
The main goal of my throttle mapping is SMOOTH, both on and off the throttle.
We have to realize that S and T modes in the factory map are just different levels of restriction to what the engine is capable of. T mode basically restricts MAX throttle to around 50-67% depending on gear. S mode is restricted in low rpm and max throttle is limited in gears 1-3. This makes the bike feel lethargic and silly for a 1200.
What most guys have selected is the following:T: a straight and linear throttle. I remove a TAD of the engine braking to try to make it smoother on/off the throttle.S: a more aggressive throttle map. The more you whick it, the more the engine whicks it. I remove more engine braking usually to make the bike charge corners hard.SS: ridiculous in my opinion. This map is snappy and belligerent. Pretty silly for a 600lb ADV bike, but too many guys enjoy it to leave it out of the equation. This mode requires 91 octane.
All of this can be customized to a degree.

Yes, there are multiple sources. Dyno charts, such as the one above by MCN seem to indicate that max HP is the same in both modes, just as Yamaha has said since the first gen was introduced. Do they do that with partially opened TB's? I don't know.

Beats me. I twist the handle and it goes.

Sometimes. Bob I have followed you. Sometimes you twist it and then other times......

The first owner of my bike sent the ecu to "ecu unleashed" to have it mapped,i don't really know the difference to a standard bike as i've never ridden one to compare
