Logged a little more time with the TTS over the weekend I think I am getting there.

Attached is the latest Datamaster2 VE table generated.

I'm not getting any data past 60% TPS, is this normal or am I being too easy on the throttle?

I read the TTS guide after starting with the old guide by DOC and realized I didn't set PE Mode to 10,000, it's still at 4300 so I'm guessing that's why I'm still seeing some red in the 4500-5500 range. I will correct this and do another run.

Should set the PE Mode and start over from the base map (before any Vtune adjustments) or just continue from this last Vtune run?

I have been allowing Vtune to adjust the EGR every run. is this correct and if not when should it be done?

Also wondering, once saved the Vtune file opened in Mastertune it looks like this...



Looking at the front VE for instance, 25 TPI and 3500 RPM value is 99.
In Vtune that cell is white yet in Mastertune it's red?
Not really sure what the colour codes mean in Mastertune VE tables though.

Also Front cyl has a lot of red yet rear nearly none?
Is this normal?

Any tips on how to ride in order to get the best data?
I've been trying to simulate throttle positions so for instance 4'th gear start at about 1800 I would twist the grip to around 10% and hold it to about 5500 rpm, slow back down and do the same at 20% etc etc.
Also hit the highway and ride at various steady speeds as well as slow down speed up, accelerate as if passing etc.
Since I seem to be missing a lot of areas is there a better way?

No reason to start over because of a PE mode change.  I doubt you are activating it where you are collecting data.  It looks like you are collecting enough data in enough cells to make a difference.  Good job.  80kpa is the limit for closed loop data collection.  That is probably why you aren't collection data much over 60% throttle.  If you would go back and open the log file and watch it fill in the histogram.  You would see this.  The red cells in the calibration is there for scaling or to show a range.  This can be turned on and off under table option at the top of mastertune.  If it is off.  The cells that you change will be blue.  This is handy when blending.

You got that pretty close.  I would blend, and see how it runs.  Blending:  Take the last known good cell and carry it out vertically.  Front  750 is 72.5.  Make all cells from 7% to 100 in the 750 72.5.  1000 rpm is 79.  Take 79 and make 15% on up to 100, 79.  1125 would be 81.5 from 15% on up.  Yellow doesn't count.  Not enough hits for a good change.  1750 doesn't have the yellow so 90.5 would be carried to the right.  Blending up is basicly the same.  3% column last good sample is at 2750.  So, you blend up 3000 and on with 58.5.  5% would be 57.5 in 3500 and up.......  The 5000 at 40% can be blended up and to the right.  That whole corner would be 94.

Thanks for that! 

I think this is what you described...

Do I need to modify the main Lambda table (currently all set to .981) ?

I was also getting a fair bit of decel popping during my test rides.
I read in the tuning guide to make the first column of the lambda table richer. What would a good target be for that?

Thanks
Steve

I would make another run how things are set up now.  Then change the AFR table to how you plan on running it.  Once the AFR is set how it is going to be ran.  Then address decel popping.  What AFR does your bike want?  If popping exist.  Add 10% to the AFR in the area that popping is occurring until pop goes away.

What do you mean by "What AFR does your bike want?"

How do I determine what the AFR should be across the Lambda table?

[hrdtail78]

Meaning, I can't tell you at what AFR your decel area wants because I don't know.  There is lean decel popping but if you are too rich.  It will pop also.  Rich pop is usually a single loud pop. 

Putting the AFR back to original is a good starting point.  Then you can decide if you want to run that much closed loop or to shrink that area a bit.

I am not good as others at tuning over a forum or by email.  A lot of what I do or don't do is based on the bike being in front of me.  The sound and how it responds while I am putting it through it paces.  I certainly don't mind giving guidance but you are going to have to make some calls based on what is in front of you.  Please don't take this as rude.  I do not want to go outside of what I think my limitations are and give you bad advice because of the limited info I do have.

If you want to email me your cal.  I will set your AFR table as an example and you can decide if it will work for you or not.  Or post the cal here.

You can also use the extend feature , it will be closer for your VE above the 80 KPA range .. Post the afr table

This is a great point.  See, I don't extend to the right very much because I am sampling that area.  I only really extend to the right from 1500 and down.

[GMR-PERFORMANCE]

I would use the extended feature and in the 100 KPA add like 7% from 2000-3000 and 2-4 % from 3000 to 6000.That will get you very close for V tuning with closed loop sensors . I would not tune withe PE fuel engaged. You need to sync the ve to the stated AFR you call out. Once you have done that you can then turn PE fuel back on adjust it what ever.   Again post the AFR table

Here is the last Mastertune file. I have not had time to complete another run yet as you suggested in your last message.
Note, the latest version of Mastertune saved it as MT9 and this board only allows file extension up to MT8.
I manually changed the extension here to MT8 so once downloaded change the MT8 back to MT9

WIll post AFR table in another message.

AFR table...

[KVSteve]

I would use the extended feature ...

What is the "extended feature"?
are you referring to the Advanced option when using Vtune?

This should be an easy fix for the mods.  I tried to report it to bring to their attention but can't find a button to do this.

[GMR-PERFORMANCE]

I would suggest you tune in MAP not TPS , turn off PE ( set to 10,000) alter the VE to a number you want vs the straight across , I can alter the map if you want , let me know

[KVSteve]

Is my process right using Vtune?

Original CAL + RUN1=CAL1 (load to bike)
CAL1 + RUN2=CAL2 (Load to bike)
CAL2 + RUN3=CAL3-FINAL

I notice Vtune allows you to add multiple data files, should I be using the original CAL every time?
For example,
Original CAL + RUN1=Cal1 (Load to bike)
Original CAL + RUN1 + RUN2=CAL2 (Load to bike)
Original CAL + RUN1 + RUN2 + RUN3=CAL3-Final

Maybe it doesn't matter but it occurred to me I could be doing this wrong.
