    AFR Table Advice From The Experts

    Getting ready to do some fine tuneing on my AFRs this weekend. Take a look at the table below that I came up with and tell me what needs to be adjusted! I know there are guys out there that have been doing this a lot longer than I have.

    idle to 3000 RPMs looks a little lean to me..my ski didnt like anything above 13-13.5 in that range..

    It is lean there but your not going to hurt anything. Otherwise it looks good to me.

    Looks good. Is that a chart you made up? Or some type of datalog from your ski? I see you have the rude controler, so do I.

    You and I have a very similar set up. My afrs at idle are around 12.5, then as the gets to plane around 4000 it jumps to 14.0.
    At 6000 I am at 13.0, with it falling to 12.0 at 8500. At these settings after a recent 3 day weekend and about 6 tanks of fuel I had about 2 tbs of slop in my catch can.

    This is simply an Excel spreadsheet that I created to graph the curve of the AFRs, its easier for me to see as I am a visual type person. The numbers in the table were taken mostly from research from this forum from many different setups and tuners. It seems as if there is no perfect AFR setup, atleast not a setup that everyone will agree on. I have tried to take notes from those here that continue to post up good solid information in all areas of these machines. Some like to run a little rich to stay safe while others tend to lean them out a bit, sort of running just on the edge of disaster.

    I like it. I know when I get out to the river. And am riding around trying to adjust each colum, I forget where I should be. So your right about this being a good visual. Can look and remember what your trying to aim for.
