    VCM Scanner (Beta) now has actual histograms

    What we've called Histograms in versions 2.24 and older were not actually histograms.

    VCM Scanner now has actual histograms.

    They can be found in the Graph display.

    Go to your "Graphs Layout", click the drop down icon for "Add Graph", and you can now add a histogram.

    A RPM histogram is now also included in all the default layouts.

    Awesome..

    hey heads up.. the latest beta seems to have a bug on the graph display. +, -, AVG, etc is cut off.

    I think that's a DPI issue. Does the current release version have that same issue?

    actually, it's because you have a long named Graph.. and it's expanding that list wider.. I'll see if we can come up with a more elegant solution.

    OK understood but I've used this layout withthe same graph names since at least 5/2021. I name/date my layouts

    Yup, we've identified the problem and it will be resolved in the next beta.

    Thanks!

    Handy. Spends most of her time at -3 to -2% on the pull.

    Thanks!

    Keith, have you ever considered adding MODE to our graphs.

    I always use the example if someone builds a 20 million dollar house in a 100K neighborhood that doesn't mean it's now a 1 million dollar house neighborhood.

    I don't think adding mode would be too terribly difficult.

    Can you give me an example of how you might configure it, and a common use case?

    Thanks for the consideration..

    I think it would have to also include some rounding down of the units... So the results would show say -5% instead of -5.3285%.... or even -5% instead of -6% or -4%.

    Else using mode would return numbers too limited in scope.

    I do this in excel for old chip car tuning. (yes I still do this.. lol)

    I'll use a formula to round down the numbers like this. - note this is not just taking decimals off but rounding by 2, 5, 10, whatever.

    =ROUND(X/Y,0)*Y

    Where X is the unit to be rounded and Y is by what.. 5's, 10's, 1's whatever.

    with Y = 5 above that would return

    7 = 5
    2.5= 5
    3 = 5
    9 = 10
    2 = 0


    But I think Mode would be helpful for any graph plotting fuel trim error or Eq error. It would be helpful to know say a car is most often 5% rich in a area as opposed to an average number that includes a super high or super low outlier.

    If a cell has (10) +5% hits and (1) -20% hit the cell would report +5% instead of 2.5%...

    2 more suggestions to add to the scanner if possible is can we please have conditional filtering and ability to include flags in our filtering

    Conditional Filtering
    E.g. MAF tuning requires two graphs, 1 closed loop and 1 open loop. Each graph has it's own filters
    With the advanced filter I could have just 1 graph.
    Code:
    If (closed_loop == true && my_closed_loop_filter_conditions == true)
       {
       Populate_Data();
       }
    Else If (open_loop == true && my_open_loop_filter_conditions == true)
       {
       Populate_Data();
       }
    Flags
    E.g. Fuel trim cell = 6 and throttle control source = Pedal or cruise
    6310 = 6 AND (12133 = "Pedal" OR 12133 = "Cruise")

    I really often get the issue, the chart show different value than the channels. does anyone know, what can be the reason?

    The channels display shows your nearest data point. It does not interpolate.

    The chart display draws lines between data points, and if you hover anywhere over that line, it shows you the interpolated data between the two data points.

    faster polling interval does not solve it? any solution to fix that?

    Ditch the SAE channels
