all of these functions can be done directly in the scanner software...
no need for excell sheets anymore....
the IFR one has been out for a while and has a lot more stuff to it now...
everything else is direct copy and paste multiply functions in the scanner/editor from histograms...

I disagree about the need for spreadsheets particularly on the MAF side. There is no curve fitting built into either the editor or the scanner that I have found. Smoothing is not a good substitute. Without a decent fitting function you could end up with a very nasty looking transfer function. The spreadsheet also gives you the ability to fit only certain areas of the curve that have changed.
There are a lot of ways to do this. Personally I prefer using a spreadsheet and having more control of how the data is manipulated... not that it is necessarily a better approach.

Tim,
The Excel tab in the LS1 MAF spreadsheet is labeled LS2. Is this a typo? Or is there no difference between the two?
It should read LS1. I forgot to change it when I made the LS1 version.

Thanks. I've got to do some VE and MAF tuning this weekend, I'm hoping these will speed up the process or at least make it more accurate.
The MAF sheets are very useful if you use them correctly. The main benefit is that you can easily correct and refit certain areas without upsetting areas that are already done.
When we SD tune an LS2 and the Ve table is dialed in we record the fuel correction on the wideband and plot that data into the histogram function. The histogram can be setup with the MAF high or MAF low for the LS2.Originally Posted by Tim05GTO
