EvoScan 2.5 and LC-1 skipping?

Hey guys, I am having problems whenever I log my LC-1 wideband via EvoScan 2.5. Whenever I log the wideband, the wideband readout would skip around some cells if I am logging only a few parameters. I am using a Sewell Direct usb to serial adapter. I just want to know if anyone is having the same issue I am having and if it's normal to see the wideband readout skip.


for example: (i made up these numbers)

RPM WideBandAF
3218.75 12.2157
3281.25 11.9364
3343.75
3406.25 11.8482
3437.5 11.8188
3531.25
3531.25 11.6865
3656.25 11.6571
3687.5
3781.25
3906.25 11.4954
3968.75
4093.75 12.1863

i do have a macro for excel to fill in the gaps based on the average of cells above and below the missing cells. looks correct in a graph unless you have big gaps.
Sub FillEmpty()
Application.ScreenUpdating = False
Application.Calculation = xlManual
Dim cell As Range
For Each cell In Intersect(Selection, _
ActiveSheet.UsedRange)
If Trim(cell) = "" And cell.Row > 1 Then
cell.NumberFormat = cell.Offset(-1, 0).NumberFormat
cell.Value = ((cell.Offset(-1, 0).Value + cell.Offset(1, 0).Value) / 2)
End If
Next cell
Application.Calculation = xlAutomatic 'xlCalculationAutomatic
Application.ScreenUpdating = False
End Sub

Readout skip is normal. I get it too. You can attach the LC-1 to the ecu. From what I remember there are no skips.

What chmodlf said. The LC-1's serial data rate (at least, as implemented with EvoScan) is abysmally slow. Logging via the ECU results in a much more reliable result.

Ok, let me try this out. Now, all I need to do is look up how to make a macro on excel. :P

damn, i really didn't want to go that route but if it will give me better results I guess I better suck it up and do it then. Anyways, thanks for your help guys.

Just ignore the spaces and approximate in your head what the AFR is, or log a couple more items. I always log around 10 items (plus the calculated stuff) and there are no gaps, yet the logging resolution is still quite good.

Haha! I made a program for this a long time ago. Funny to see old problems pop up again. I use logworks3 now, but here ya go!
