I'm in the process of buying a 110" 2010 SE Ultra.  I would like to use something like the TTS Mastertune to run the stock bike at 14:1 closed loop until I'm sure it's not going to be a warranty queen.  I've read the TTS can be used to replace the stock map if going into the shop.  I don't want to do the full "Fullsac" treatment until I'm sure the bike is not a lemon and I don't want to run uber hot putting the heads at risk while I'm waiting.  Anyone else think this way?

Thanks,
Richard

The 10 doesn't use Closed Loop Bias any longer and I think all you have to do is change the target AFRs to 14/1. The tuners of Steve Cole can clarify

[Steve Cole]

You cannot get to 14 : 1 and remain in closed loop. 14.34 : 1 is about as far as you can go on a 2010. You can however run it in open loop and go that rich if you like. TTS is the only system that allows you to return it to stock configuration provided you do an upload before you put a tuning file in place.

I'd be happy at 14.34 : 1 over the 14.7 or whatever the stock ECM is set at.  I just want to keep the temperatures in check until the bike breaks in and I'm sure it is good.  I use a device called GS-911 on my BMWs and love the ability to log data for later analysis.

Is it simple to do something like this?  I would guess that 14.34 has got to be cooler than stock.

Looking at your documentation, closed loop should still be active at 0.965 lambda which is 14.17 : 1 AFR.  Am I reading this right?

.977 Lambda is as rich as you can go and still be in closed loop. Where are you reading something different?

Manual on the tts website (tuning v1.22), page 32 (The main lambda...controls closed loop...0.965 to 1.020).

If your control AFR based on the lambda table, what function does the VE table do?

Thanks for the help,

For a DBW touring bike, what does V-tune actually do?  From my reading, the VE tables are modified but what is the goal?  I like everything I've read about the Mastertune system but I'd like to know what it tunes at least at a high level.  If the goal is proprietary, then what is the outcome?  A bike tuned to achieve what?

For a DBW touring bike, what does V-tune actually do?
VTune provides VE numbers that correspond to proper calibration for a given engine's characteristics for a given Lambda or AFR.

the VE tables are modified but what is the goal?
A properly calibrated smooth, responsive, efficient and maximized running bike.

...I'd like to know what it tunes at least at a high level.
Not sure of what is being asked here.

If the goal is proprietary,
The 'goal' is not proprietary.

...then what is the outcome?
A properly calibrated smooth, responsive, efficient and maximized running bike.

A bike tuned to achieve what?
A properly calibrated smooth, responsive, efficient and maximized running bike.

Good Morning ssls6,
If you haven't already, go to the TTS Mastertune website and download their manual "Using Mastertune and Datamaster to Tune HD Motorcycles" Version 1.22.
It contains a wealth of info to include V-Tune.
I'm 100% satisfied  with Mastertune on my bike. Great product with terrific support.

"The Main Lambda table directly controls closed-loop AFR over a range of values, typically0.965 to 1.020"

Sorry for any confusion but the above is what is in the manual. We gave a typical range as it is not necessarily the same all the time. Vtune is used to calibrate the VE table so that yoou get the proper LAmbda values out of the system. The VE tables are what tell the ECM how much air is entering the motor at any given time. This is used to calculate the proper fuel command.
