Lightbulb Tuning Spread Sheet 1.0.0

I used alot of resources during my supercharger tuning. I put most of them in a spread sheet to work out my numbers. I polished it a bit.. I wanted to open it up for comment and evaluation. I was very successfull using it and nailed my timing, LTFT, and A/F ratio using it.

Anyone is welcome to use it, as it's a compilation of best practices and formulas. It covers the basics LTFT, IFR, Timing...

Comments and constructive criticism encouraged

Nice job. Good explanations.
One constructive comment. I don't know if I would suggest AFR > 13 for N/A cars. I see a lot of N/A guys talk about shooting for 12.8 - 13.0 AFR. But I suppose it could just be the difference between measuring at the tailpipe and measuring in the pipes near the engine?

Question:

In step 4 under quadrant - you say: "Performance Quadrant: Find your smallest rpm / g-cyl combination in your WOT run (In blue) everything to the left and down is the likely area for timing at WOT. These are the values you should modify."

Should that read everything to the right and down or am I not understanding?

Yep, typo.. And fixed a A/F reference value. Here is an updated file with the fixes.
