Adjusting VE Fueling tables with BLM data Tutorial!

[EagleMark]

Yup Dave got it! Actually he's the one who taught it first!

When I said to fill in spreadsheet with similar numbers after taking out History Average with 5 or less counts... this takes a little practice and thought, look for patterns and trends in the BLM History table numbers you entered in spread sheet. You will never be able to data log them all. But they all count! Remember Interpolation of cells? Remember smoothing by using Graph mode and visual pictures of the graph? What is going to happen if you adjust say 8 cells in an area to 108 and one did not have data? When you paste the VE table back into bin and look in graph that cell is going to be a Peak or Valley! There will be lots of manual cleaning up to do to make the VE table smooth again.

Example: You have the 800 RPM row with BLM data like this
xxx,xxx,xxx,108,110,112,114,xxx,xxx,xxx
Fill in the blank/xxx cells with
105,106,107,108,110,112,114,116,118,120

If there was no data in row above that, the 400RPM row what is going to happen when you paste in VE to bin and look at it in graph? It's not smooth, way off and is going to effect the 800 row you adjusted because of interpolation.

Final VE table you use in your rig does not have to be perfectly smooth, but should have a visual shape to it. Because of interpolation starting with smoother table makes adjjusting from data so much easier.

I know this an old thread. Thank you EagleMark. That was a well done tutorial.

im taking an hour and a half trip on Sunday. It will be a mix of higway and local driving. You think TunerPro will be able to handle that long of a log for the history tables? Or should I split it into multiple logs?
