Sod it,
Maybe someone else can work it out
Also might prove useful when you get the wideband set up and do some logging
https://www.dropbox.com/s/cupe19cr1q7x0 ... 1_21xx.xlsThis is using live data from my last session
Things that need to be filled in in the Calculations tab:-
Measured AFR tableTaken from FC log file :-Open Map Watch
Open log file
Select AFR table
Select Average
Copy table and paste into Xcel
SamplesFrom above chart select samples
copy table and paste into Xcel
Target AFRTaken from FC-EditSelect Inj Map
Choose AF Ratio
Copy table and paste to Xcel
Current BasemapTaken from FC-EditSelect Base Map
Choose Base (mSec)
Copy table and paste into Xcel
Sample ThresholdManually EnteredDetermines the weight of the correction applied
Corretions based on measurements with samples < sample threshold will be scaled down
I used 10 so cells which only have one measurement make little difference but with 10+ samples I was applying the whole correction
OutputNew BasemapCorrected version of the basemap based on the AFR samples
Then copy new basemap table and paste special into "new fuelling map" table. Select Values
Switch to Graphical Comparisons tab
Look at the new fuelling map chart. You might well see that it's a bit peaky as in the example data. Smooth it by hand - lower peaks and raise points either side to achieve a smooth curve. Again look at the example data in the xls, Original Fuelling Map was previously hand smoothed by me
When you're happy switch back to the calculations page, copy the values from the "New fuelling map" table and paste into the Base map (Base msec) in FC-Edit
What I'm trying to achieveRecalculate the base map so that the measured AFR closely matches the AFR table plotted in the INJ map. Once you've done that AFR changes are as simple as typing in the desired AFR in the INJ map in FC_Edit
I also have a spreadsheet for calculating IGN timing but that's really really complicated
