Look for the following in sae_generic.txt in program files/efilive/configuration.
Unsigned Numeric
# ----------------
#
# The units column is the units code from the *UNITS section above.
#
# The Low and High columns are used to determine the chart axis and the
# gauge scales.
#
# The Fmt column defines the numerical format given as width.precision
# where width is the total number of digits counting the decimal point as
# a digit. The precision is the number of digits after the decimal point.
# Width may be omitted to prevent leading spaces being used to pad the
# formatted value. Use precision=0 for no decimal point.
#
# The raw value returned by the PCM is converted into the engineering units
# by either multiplying by or dividing by the Factor depending on the Op(erator)
# Then the Offset is added - Factors and/or offsets may be negative if required.
#Units Low High Fmt Op Factor Offset

I have changed the FMT but it doesn't do anything... If I change the chart I can see the decimal places I need...
This is on the calc.ben1_E38.

Go to Folder "C:\Program Files\EFILive\V7.5\Configuration" and open file 'sae_generic.txt'.
Look for this section:
# Serial Wide Band BEN factors
# =============================
*CLC-00-996
factor 0.0 2.0 .1 "{EXT.WO2AFR1}/{E38.AFRATIO_DMA}"
*CLC-00-997
factor 0.0 2.0 .1 "{EXT.WO2AFR2}/{E38.AFRATIO_DMA}"
Change the ".1" to ".3" in both places for 3 decimal places. If you want 2 decimal make them ".2".
You will have to go back and change it if a new update comes out and overwrites the file.
