Pump voltage Rescaling histogram to match tunes scaled table

I’d like to rescale the histogram table for fuel pump voltage to match the scaled fuel pump voltage table in the tune. It seems like it would be difficult to make meaningful changes with two different scales. Does anyone have any suggestions on how to accomplish this and/or have a work around?

thats by design so you get more accurate info

you only use the points you want

Just for clarification please. Currently SP**FNRFNRM_FLOW has values that are not round: 0.067, 0.668, 4.008, 5.344. Can I change the scaling of this normalizer to match the histograms X axis or are you suggesting just using the columns that are closest in the histogram (rounding up/down)?

anything with SP** you have to correct by the scaling percentage when you change injector data

You want to set it to whole numbers.

Something like so:

MAXXXXXX 8 (max value should be 10.xxx for 80lb injectors.)
4.000 7
2.000 6
0.400 2
0.040 1
0.000 0
0.000 0
0.000 0
0.000 0

Yes, you can change an existing or create your own... Unless newer ADX files are locked...

I do it so the histograms match my MAF and perload values.

Tool bar: Acquisition
Menu: Edit Definition
Menu: History Tables

Select the table you want to edit and save as another name first so you don't overwrite the original.

If you need to change the number of rows/columns, do this first, as changing row/column count will reset all row values.

Tabs at bottom select the row/column you want to change.

Input your values in the appropriate row or column and save.

As far as getting the scaling to match, you may be able modify and/or create new values(PID) with an equation to convert the scale percentage and select the new PID as your row or column object in the history table.
I've done it to correct the difference between my wideband display, and data log.

It's the same basic process as above, you're just editing values instead of history tables.
