Newbie looking for advise with first tune

[Dieselman]

I have the map up with the cell counts but when I go to the average value screen it is all zero's????

[Dieselman]

I should also add...

• Try to keep a steady throttle when logging for tuning the VVE.
• If you need to add / remove throttle, do so in a gentle fashion. No fast movements!
• Get as much varying data as you can, hold it in first and take it up to 6000 RPM with very little throttle. Hold it in a higher gear and load it up. change up / down gears when cruising to mix up the data a bit.
• Don't forget to filter the transient states out!
• Get lots of data and apply, then log lots of data again.

OK I will be nicer on the throttle

It looks like you don't have the PID selections right and I think from memory that the default BEN map is incorrect. Try this...

1. Open ScanTool with the log file of choice.
2. Open the "PID's" tab or press <F8>.
3. Under the "System" drop down box, select Calculated.
4. Double click the "Ben Factor Bank 1, Serial Wideband, E38 Style" PID.
5. Allow the program to re-plot the charts and maps.
6. Open the MAPs tab or press <F11>.
7. Go to your BEN map.
8. Right click the map and then select "Map Properties".
9. Select the "Data" tab.
10. In the "Parameter" drop down box, select "(0) BEN Factor Bank 1, Serial Wideband, E38 style (factor ).
11. Open the TuneTool with your current tune and go to B8101.
12. Press <F2> to bring up the VVE table cells and then click on the grey box in the top left corner of the cell window to select all cells.
13. Right click and "copy with labels" or press <SHIFT>+<CNTL>+C
14. Go back to ScanTool
15. Select the "Column" tab
16. click "Paste Lables"
17. Select the "Row" tab
18. Select "Paste Lables"
19. Select the "Cells" tab.
20. Click on the "Constrain cell size" box so it is checked.
21. Set the minimum width + height to 30 + 10.
22. Select the "Empty" tab.
23. Note that you can check the "Hide Empty Cells" box to remove data from the MAP. This can be used to "hide" cells with only a small number of samples and helps to remove random spurious data that can adversely effect the VVE shape. It's good to hide cells with less than 50 "counts", it's probably acceptable to hide cells with less than 10 counts. You can turn off the hiding of cells if you are working on a specific issue.
24. At the bottom right, select "Save As" and choose a new name for your map.
25. Select "Save"
26. select OK

You should now have a working map for BEN factor correction. If you want to compare maps between enabling and disabling the "hide empty cells, you can make two maps up and just switch between them.

Thank you very much Simon


The map works a treat. I hope you are ready for more stupid questions in the future though!!!

[swingtan]

always here to help

[Dieselman]

OK time for another stupid question. When BBL how do you put BEN's in the PID selection???

I looked through the list but could not find it

[swingtan]

BEN's are a calculated PID, so don't work directly on the V2. The data to produce the BEN's are still recorded on the V2 and you can then select them in ScanTool. Actually, I think you can "preselect" them in the BBL setup so they are there when you open the log in ScanTool.

Simon.

I just checked ...

Open V8 Scan&Tune
Select <F5> BBX
In the "Selected PID Lists" window, select the controller / PID list you want.
To the right of the "Selected PID Lists" window, click "V7"
In the "Pre-Selected Calculated PID Names", add the BEN PID you need.
You can also name the predefined dash page you want to use.

Thanks Swingy It is all good now

Cheers

Hello everybody,

What does the filter setup do in this screen shot???

Thanks in advance

[swingtan]

My understanding is.... Nothing for serial Wide Band data.

For Analogue WB signals, you can average the analogue over a number of samples. The wording of the text is "Analogue/Digital" which reads to me (and many others) as Analogue <and / or> Digital, but it should actually be read as, Analogue "TO" Digital,
