Ok so after much deliberation and very little thought I have arrived at a stratagy for my CLB tables.

Assumptions/Considerations:

• O2 sensor sensitivity rapidly decreases begining ~750mV
• Striochiometric AFR is 450mV
• Doc has previously recommended a range of 640mV to 780mV
• TTS Tuning Guide April 2009, states accurate range is 250mV to 800mV
• TTS Tuning Guide April 2009, states normal range is 250mV to 675mV
• TTS Tuning Guide April 2009, states not recommeded above 800mV
  
• Decel is not in closed loop & not controlled by CLB tables (20 kPa)
• Heavy load operation is not inclosed loop & not contolled by CLB tables (90 -100 kPa)
  
• Review of my Datamaster File for areas 'I ask for it' TPS% greater than 40 all fall out of CLB as the MAP is 90kPa+
• Half smile riding where TPS% > 15 but less than 40% are averaged about 65kPa (+/- 10)
• The rest is cruising with MAP averages around 36 kPa
  

So the CLB is basically the cruising portion of your map

So with all that in mind, I start in the top left corner of my CLB Table and increase mV as I increase MAP and RPM. I give more weight to MAP as it seems to corrolate more closely with what I want, while RPM seems to try and catch up to where I want to be.

The only exception I have is that top left corner, like on [yso191] Steve's CLB table. It occurs to me now matter how I ride, when in closed loop, I will always start from that area of the CLB table. So my Bias is to pump that number up a bit to where the numbers surrounding it are actually lower.

Now that I had a statagy for populating my CLB table I needed to put values to my generality. My minimum number was 642, my max was 720. I wanted to stay closer to 700 than 750 as I want to ensure as accurate a sensor reading as possible while in closed loop, and as mentioned above the degredation in sensitivity seemed to occur around 750 based on the narrow mV sensor curve.

In conclusion i don't think the CLB table adjustments gain you too much as variation between a number like 450 and 809 gain you (14.68-14.09) 0.59 richer on the AFR. In relation to a Open loop POWER setting like 13.2 these mV adjustments seem some what trivial to me. Perhaps thats why I couldn't find much information on CLB stratagy...

So here is what my CLB table looks like.

MAP--->
RPM 40 50 60 75 90
| 1000 681 661 681 700 720
| 1750 642 661 681 700 720
| 2500 661 661 681 700 720
| 3250 681 681 681 700 720
| 4000 700 700 700 700 720

So Theory/Stratagy out of the way now its time to tune/test.
I am happy to take critisim, constructive of course, on any thing I have here.

 

Well done Zacharia. I think this post will be a reference for people wrestling wit the same issue(s).

I was helping a friend a few days ago start over with the v-tune process to fix some cold starting and mileage problems.

I made a mistake and picked the wrong MAP, I did not notice this until after we v-tuned and whet through the whole process.

His bike is a 2009 SERG the MAP I should have picked was UJ205 but I used YB205. From the description the only difference is exhaust and cams.

I examined both maps and the there were some differences in the AFR table and a few others like the warmup and PE tables. The timing maps were the same.

The question is can I just copy and paste those tables that are different (leaving the VE tables and CLB alone since we have already v-tuned) and be ok or are there "hidden" values that we cannot see in the MAP?

I have actually already done the copying and pasting but I have not loaded it and I want to re-assure my buddy that there is not a problem or redo the whole thing if there may be a problem.

 

Hi people!!!

I'm having a problem with mi TTS map, when engine is hot it stop itself.

I've made the V-tune and everything was ok, till my last trip when I realize of that.

I think could be the idle, I've put it at 800rpm. Well, not from the begining of the table, but when engine is about 100º

Should I increase the idle? or could be another problem?

Thanks!!!!

 

Maybe a bit more about your type of bike and which map you used would help us out.

 

Ouch, Idle should be 900+, less than than and you won't maintain proper oil pressure. I would guess this is the source of your heat issue. Put your Idle at 960-980 and see if that helps

 

You should be ok. you can set your AFR and PE(should start were your 100% TP left off on your AFR graph) and warm-up any place you like. You may want to do somemore Vtune runs. the VE's are going to be differt for cams and exhaust. Do one more run generate the tune and see how many cells change. if less then 5%, your done if more you may want to do more vtune runs.

 

If EITMS is kicking in when its idling at 800 rpm, it may not have enough momentum to keep going.

 

+1

3.3 of tuning guide when adjusting idle RPM do not set idle speed below 900 RPM as this could cause the oil pressure to fall to low resulting in engine failure.

 

Thanks you all!!!!

My bike is a FaT Boy 07, and I'm using the QD176-000-B1.mt7.

Now I've increased the idle in this way:

-16º 1192
0º 1152
16º 1088
32º 1000
48º 992
64º 984
80º 936
96º 936
112º 904
128º 904
144º 936
160º 936

Should I increase it a little more? or this could work ok?

Thanks!!!
