TunerCat A/F Ratio Spreadsheet

I created this spreadsheet and I figured some of you could get some use out of it.

Change the values in the two tables at the top of the spreadsheet. These are the same two tables you will see in Tunercat; 1. % Change to Air/Fuel Ratio VS. Coolant Temp at WOT and 2. % Change to Air/Fuel VS. RPM at WOT. This makes it much easier and quicker to tune. :) Once you have the tables the way you want them, simply copy and paste the values from excel back into tunercat.

I've got Tunercat, but never tried this table. Can it convert to F or is everything in Tunercat in C?

You're joking right? :rolleyes:
You do know that a spreadsheet like this is nothing new and there are others that do the same thing.
There is even a more advanced version that Chrisitan Millard wrote that allows you to use this inaccurate data along with actual a/f data from a wideband to tweak the pe tables.

I'm new to this... are these tables bad? What part of the data is inaccurate?
