So I think I’ve got a handle on the TTS Mastertune concept.  I’m going to try and summarize what I think I’ve learned so please double check me in case I’ve got it wrong.  The bike in question is a 2010 CUSE5.

At a high level,

Step1:  I need to pick a canned tune close to my current setup.  In my case that would be a stock bike so the closest match would be EUJ009-01.  If I do a stage1 upgrade to my bike, I would still pick EUJ009-01 because it is the closest match.

Step2:  Edit the tune file from Step 1 and adjust the main lambda table so the bike is in closed loop mode for all but the last column (100 kPa).  I need to input something between 0.977 to 1.020 in each cell to ensure closed loop operation.  I’m doing this so I have accurate VE tables in areas that will return to being open loop later.

Step3: Load the map into the bike and and start data collecting.

Step4: Process the data with Vtune to create an improved version of the tune from Step2.

Repeat steps 3 & 4 until the tune cannot be improved (it’s only slightly changing).

Step5:  Somehow I must retrieve the original lambda table from Step 1 and merge it with the improved VE tables from Steps 3 & 4.  My goal is to end up with a clone of the tune file from Step 1 but with VE tables from Steps 3 & 4.

Step6:  If I want to run a little richer at this point, I can change any entry in the main lambda table that is greater than 0.977 to 0.977 (for closed loop) or even less (for open loop) and my accurate VE table will ensure that I hit it.   Load the final tune and I’m done (until I change something like if I do the actual stage 1 later).

Does this sound about right?

Step7:  go find a good dyna tuner and let him/her work their magic.

True but where's the fun in that

Simple Just highlight the entire Lambda table then "click" on the set to original button

Step6:  If I want to run a little richer at this point, I can change any entry in the main lambda table that is greater than 0.977 to 0.977 (for closed loop) or even less (for open loop) and my accurate VE table will ensure that I hit it.   Load the final tune and I’m done (until I change something like if I do the actual stage 1 later).

You may want to adjust the timing some.

Does this sound about right?

With my few comments above that pretty much covers it.

Thanks Steve, I'm feeling pretty good about it now.  I've got an 08 DWG and a CUSE5 on order.  My wife has a 09 DXL so all I need now is a 3 bike special    I think I'll at least go for the two bike setup.  The wife will just have to suffer

you just got the approval of the mastertune guru, Steve is the mastermind behind mastertune
I just tuned a 2010 ultra and what we did at the beginning of the V-tune was collect data in neutral, have a few fans blow on the motor. won't start collecting data until 180 degrees, capture as much as you can before it gets too hot, this will give you data as you throttle up the rpm scale, then ride it on V-tune, I found that if I ride some hilly areas it helps

[ssls6]

I'm 200 miles south west of the Talimena drive.  I plan to do my tuning there.  Very hilly with lots of curves to engine break into and power out of.  It's 50 miles long so I'll run it left to right, tune, then run it right to left, and tune.  I'll take your advice and stationary tune first.  I have a massive shop fan.

Ok, so what do people in Florida do?  I live on the highest point (60 ft) in Florida.  Do I drive up my street 100 times or what?

You will have to get off the bike and push when you hit a hill

I would just drive around for 1/2 hour on open roads using different gears (like break-in).  You could plan on a weekend in Georgia, I know they have hills.  Could be fun.  When I go to Talimena (200 miles one way then another 50 to run it) I'll stay overnight in a hotel, drink a few beers, BS with other guys/gals who are there almost every weekend to run the drive.  Fun with a purpose, what's better than that?

I'll make sure I'm good at doing the tune before I hit Talimena.  Don't want any surprises before I'm away from home.

the reason i say that is you need to put it under load. get the rpms up and then load it. thats where it needs some juice

[sportygordy]

I'm anal,, i like it right...  Even though I've had awesome success with the Daytona Twin Tec AutoTune and their TwinTec product, a good dyna tune can't be beat.. JMHO And I'm also one of those guys that prefer to run between 12- 13.8 AFR's depending on throttle position and RPM range.   To each their own,, and you cant sell me away from something I know that runs good, cool and gives good gas milage..

When your stuck with no hills to add load you need to create some. Add weight to the saddle bags, ride it double up or dragging the rear brake all work to increase the load on the bike. If you use the rear brake just be careful not to over heat it when doing so.

Funny you should mention this Steve.
Pic below shows what a rather healthy 117 can do to a rear rotor with exuberant street V-Tuning.

Ordered a dual TTS kit today.  Look forward to playing with it.
