Fuel adjustment tables

[dnar]

Hi Guys,

I put together a spreadsheet to assist dialing in fuel.

Lookup your current AFR in the left hand column, go across to find the target AFR you desire, the adjustment percentage is then read at the top of that column.

I hope the calculations are correct, it is based on adding/subtracting a percentage of fuel based on fuel = 1/AFR.

Enjoy.

Sorry to bring up an old thread but I thought the chart that op posted was very interesting. Does anyone know if the chart is correct?

Also, I was looking through different options within my in tune and the wot fuel adjustment setting confused me a little. If I ever need to adjust my AFR, which way would I adjust to take away(lean) and to add(rich)? For an example, going left says rich but goes to negative percentage. I'm guessing going left would mean taking away fuel to go leaner?
