2012 TTS Tuning with engine changes

[Thumper Buttercup]

OK,

New Folder and 6 renamed vtune files, I started with #021 and went to #026

6 renamed vtunedata files, again started with #21 and went to #26.

I did nothing with the last file that we did the data run with mike, so this is
just the vtunes and the data files.

Mike just change the AFR back to original, did I forget anything else??


If we get all our work done this morning, I fix that last file
and do another data run, they took the rain and wind out of
today.



Work first then play.

that's all I saw. 

[Thumper Buttercup]

Mike,

    Let me know if the files make sense now, I took the BPZ176-vtune-026
and turned everything back on and made the bike BPZ176-vtune-027.

    We went out and did a data run, it dropped off line once but we got it
restarted, I did not hear any of the knocking but there is a lot of it going on
by the data we got.

      Let me know if the files are making sense now.  We are getting a little
weather for until about Monday so I'm in no hurry.  Let me know what you
think we should do next.

I uploaded the ScanData-005 here  https://www.box.com/s/c312f6e8be7a9c7310dd

still doesn't make sense.  was vtune cal 26 what was created with vtune data file 26, or what was run with vtune data file 26?   

here's how I want you to list these so they make sense to those of us following along:

vtuning:  the cal that is ran is labled vtune-xxx and the vtune data recording that was recorded with that cal has the same -xxx number

scan data:  the cal that is ran is labeled scandata-xxx and the scan data recording has the same -xxx number. 

[mayor]

do a scan data recording with the attached cal.  I added some timing in the 60 kPa column, seeing if more timing will reduced cruise heat.

[Steve Cole]

And I thought I was the only one that got confused by it all. I have to keep the numbers all lined up so tomorrow I can remember where I was at the day before.

[Thumper Buttercup]

OK,

   I did my VTuneData backwards, so the line up starts with

Cal 22 with VtuneData 22
Cal 23 with VtuneData 23
Cal 24 with VtuneData 24
Cal 25 with VtuneData 25

Cal 26 was generated but everything turned back on and it
was made Cal 27

Cal 27 was run and it now has ScanData-027

OK now I got it.  Believe it or not I was not having problems
keeping it straight until today .


Everything is renamed and uploaded to Box.

[Thumper Buttercup]

Should I do a couple Vtune's with the timing change before
I do a data run .

I'm looking at the 3D of the knocking like Steve said in another post
it really shows the knocking better.  But I'm not seeing much for
Data when I put my mouse on it.


OK I'm getting more Data now if I turn the Graph this way and put
my mouse over the area's.

[mayor]

no, do the run as is.  The differences in fuel requirments in the 60 kPa area should be taken care of by the closed loop function.  We'll regroup once we see what the timing does.  My main goal is to see if we can get the head temps lower.  You head temps seemed high. 

[Thumper Buttercup]

OK,

Mike enjoy yourself, I'm just putting this out there to try and understand the
changes being made and see if I can get over this information hump so I can
better understand and start to make changes myself, or at least know why
the changes are being made.


Temps too cool this afternoon so got things checked out, rear plug looking black, top
of piston getting build up from running rich, front plug looks great.

Using that data run we are getting a bunch of head heat, running from 55 up
we are seeing 300+ head temps.   I see where you made changes in the 60 kpa
area but I'm trying to follow, should there be more changes in the 70's & 80's?





Now I'm trying to understand about the Timing changes we are making.  Bear with me
Mike, running the Map 50-70 kpa area in the run.

Looking at the 3D below the front knocking hit us at above 3000 rpm and 65 to 85 kpa.
The rear hit at just over 2500 rpm and 70 to 85 kpa.

My question is should we be adjusting timing in these area's or am I looking at the problem
wrong here?

dang. I was trying to scroll over that.

Here is the ScanData file these are from

This is the Vtune Cal we were running

did this change run hotter (if so, advancing was the wrong way)?  how smooth was the engine?  how well did it accelerate? 

I'm out of the heavy software stuff until Sunday, so maybe one of these other fellows will take a look and recommend changes for you for tomorrow. 

[Thumper Buttercup]

Mike,

    Too cool to run today, we will run tomorrow, I was trying to understand
the Spark Temp changes so I could make them and keep going this weekend.
We will be in the 90's tomorrow and will get a run then, just trying to understand
how much of a change to make on the Spark Temp if we have knocking tomorrow.

Don't worry about it you guys get some miles in and have one on me.

PS  Kim found the extra, get us an address next week and it will be on the
way.

[mayor]

so, you didn't run the new cal yet? 

I left the 70-80 kPa columns untouched.  We may have to reduce them, but the first thing I wanted to see about doing was getting the head temp to drop about 20-30 degree's if we could.  That will help the other columns too.     I didn't touch the temp correction table yet either.  We may have too, but lets see if we can reduce some heat first.

We will run it tomorrow Mike.

It was too cool today to duplicate what we had the other day, tomorrow is going to
be a hot one, so we held off.  If she raises hell we will just drop back and ride slower
and mess around.

[Thumper Buttercup]

OK Mike,

    I'm going to post up a Cal adjusting the Spark Temperature Correction.  I am
going to adjust the 70 kpa area where we run on the interstate.  I am going
to continue this and be on the safe side for our engine.

     I'll get it up in the next couple days, we've got weather so we are parked
for a few days.  Also my stand-offs from HPI showed up today and I'm getting
them cut down for the Exotic air filter.

[Thumper Buttercup]

Ok,

    As per the other discussion on the SuperTrap SuperMeg
we changed the exhaust to 18 disks and the closed endcap.

   Mike do you want me to just take that Cal ScanData28 and
set it up for a couple vtunes and then do a data run?

[Thumper Buttercup]

Hey Mike,

    Huge difference in the bike, it filled the blocks easier and kept in the
green more, it was 80 degrees and windy but the heat was not there
like before, and when the heat did build up when I pulled over it cooled
right down.

     We got two Data runs today, the first was Cal 29 which was your cal
28 made ready for vtune.

This was the result of Cal 29 and vtune data 29, I did not extend



This is the second run 30 with data 30, we had a few dropouts where
I had to pull the bike over to stop and restart the data but we got it
done.

I did do an extend on this one

Our plan is to go for our loop on Friday unless you think we need another
vtune, the wind was crazy today and it might have messed up the Data30
I don't know, the bike was working its butt off in that head wind.

[Steve Cole]

So the heat issue was basically solved by adding more disc in the exhaust?

Mike did a timing change in the 60kpa area also.  But the extra disks made
a large difference in the heat coming off the pipes and the way the engine
temps dropped when I was not working the engine and was letting off and
siting still.

[Steve Cole]

How much timing change? If it was only in the 60 kPa area thats the only spot it would effect, so it sounds like most of the heat was caused from to much back pressure in the exhaust.

I have found this to be the case with my last two supertrapp supermegs.  even cooler with the open end cap.

[mayor]

How much timing change?

2-3 degrees.

my guess is letting the engine breathe made the biggest difference as well.
