    AFR Table Headed In Right Direction?

    So I am putting in my Target AFR based on TP% in my CMD and was curious what everyone thinks on this current table. I found one similar to what I was looking for and modified it a little based off of recommendations and previous posts I have seen and heard in the past. In no way am I an expert, this is the first table I have done so please let me know anything I might be doing wrong or any advice for that matter.

    I run 93 Octane with no ethanol at minimum by the way.


    Edit- working on better pic now.

    Is that a MAP based table or a TPS based table? You need it to be MAP (Pressure) based.

    It is TPS based. I thought TPS is fine with a supercharger setup and MAP is what the turbo guys need to run. Why does it have to be MAP based?

    it needs to be map based so it knows what fuel to deliver at a certain pressure (map) I thought that was map based as well, my fault.

    Your life will be way simpler later is you set things up MAP based now. It needs to go from about 50 at idle, 100 with a dead motor and about 175 to 210 at WOT depending on your setup

    TP tables cannot fully account for engine load or changes in atmospheric pressures. 1/2 throttle, low on fuel, with a light weight rider will not be the same load as 1/2 throttle, with a full tank, 2 up and towing a tube. If you did make a TP table with enough fuel to constantly cover max load conditions, you would end up keeping your engine happy, but you'd use 4 times the fuel a properly setup load based calibration would.
