so I managed to log some data with the new logger, but I ended up with a .CSV file with about 10 columns of data without labels. Some of them are pretty easy to guess what they are (like coolant temp, ignition advance [very cool feature BTW!], target AF, and measured AF..) but i am at a loss about some of it..
has anyone played with this new version of the logger and have any input to help me make sense of it all?

Cerb,
I'm still trying to figure it out... How does it work? Basically it's supposed to be able to be stored in the ECU and then pulled by TB and analysed thus allowing AF ratios to be corrected without a dyno.
I can't figure out how to access the logger nor how to get the system functioning.
I've got the rest of the program working well and have been playing with maps. So far the 20102 with mods from Wayne are working great with my Zard system. It's still a little dead off closed throttle starting out in first, but I'm not sure what could be done to correct this. It is WAY better in the mid range and top end as Wayne has advanced the ignition 3deg above 7500 and leaned ot the target AF to about 12.8ish across the top...

geof3- the logging is done by tunedit, to the laptop that is running it. I is not stored in the ECU .
If you have a new version of tuneedit, you will see different option in some of the drop down menus on the title bar.
One is under Options, "install logging patch" (you'll notice that O2 voltage in the lower right corner of the screen now has 2 numbers instead of one) which then enables "start logging" which is under Tools, then a window opens offering to name the log file "TBLog.CSV" .. then it seems to go to a realtime mapping mode, and starts logging.
I ended up with a 2MB file after a 5 minute ride around the block.

Ok, am I missing something? Do you have to drive around with your computer attached to the bike somewhere? I'm not pictuing this to be easy... Or am I sitting here with my head up my ass???

nope, you understand quite clearly.
laptop in backpack while logging works well for me.
just choose a smooth route to avoid bouncing the laptop around too much

Can you send me the file you've got and I will have a gander.

quoted from Wayne:
The way this all works is as follows.
Open the tune.
Select "Install logging patch". This zaps address pointers in the program
itself so that all the data we need is in one spot. This allows a single
read command to get all the data we want, this in turn allows the logger to
sample at a much faster rate and you can be sure that all values in a log
record are from the same instant in time.
Download the map to the bike.
Select "Start Logging".
Do your thing.
Select "Stop Logging"
The file has the following info.
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15
1 = N/A
2 = N/A
3 = Current RPM
4 = Index for RPM, this shows the column in the map that is currently being
used, 0 is the first column.
5 = Offset for RPM, this shows how far past the RPM index it is towards the
next column, the range is 0 to 255.
Index of 5 with offset of 128 would mean it is half way between the 6th
and seventh column in the map.
6 = Throttle percentage
7 = Index for TPS into the map, same usage as the RPM index
8 = Offset for TPS
9 = O2 sensor voltage. This will read from 0.000 to 5.000 volts.
if you have a wide band sensor connected to the O2 input then this will
be your wide band O2 value.
if you set the output from the wideband to 0 = 10/1 and 5v = 20/1 then
the following can be done in excel
(voltage * 2) + 10 = Air/Fuel ratio.
10 = This is the target A/F ratio from the A/F tables in the ECU, this has
nothing to do with the O2 sensor.
11 = N/A
12 = Injector pulse width, 2000 is 2.000 milliseconds
13 = Ignition advance, 159 = 15.9 degrees.
14 = N/A
15 = N/A

(quote continued)
When the logger is running the two A/F values shown on screen are.
Top one is from the tables in the ECU.
Bottom one is calculated from the O2 voltage using a file called O2_cal.txt
that must be in the same directory as the TuneEdit program.
Here are two examples of O2_cal.txt files
This first one will convert the voltage values from the narrow band sensor
to A/F values, this will noe be accurate but it is better than nothing. Note
that the values range from high A/F to low A/F, this corresponds to the D on
the first line.
***********************************************************************
* First line should not be changed unless you know what you are doing *
***********************************************************************
D,5100,1024
**********************
* Each line is mv,af *

55.0,15.14
450.0,14.50
800.0,13.70
1100.0,10.00
***************
* End of file *

This second example of an O2_Cal.txt file is for a wide band that is set for
0v = 10/1 and 5v = 20/1

Homer, do you still want to take a look at my datalog?

Does that mean that I can just connect a WB sensor to the wire where the original NB sensor has been connected and tuneedit is logging WB values?
As I have already wired and connected a WBO2 device to my bike, is it possible to connect the WBO2 outputs WBlin+ and WBlin- to the original sensor connector of the bike?
