    MPtune calculated tables

    Hello all, I have never understood the tables. Mptune/calculated tables/full throttle total timing/rpm vs psi chart. In the upper right hand corner is a blacked out box with teal letters that says...X:27.817 (in/Hg) Y: 19.325 (degrees). What do these numbers represent beyond the obvious nomenclature? Are these numbers related in some way to the PSI vs RPM charts.
    Additionally If I pick out any X-Y juncture, what does the number displayed in the box represent, timing, corrections to timing or some other function.

    Is there a resource that explains these things?

    If you can help, thanks!

    purely a bug! the box in the upper right is just left there from the last 2d table you were looking at. when you click on the 3d table i should really hide that box since it does not apply.

    in the 3d table each box in the grid represents the total timing.

    Does that total timing number actually happen or is it a hypothetical number that may be reached under certain conditions?
    Thanks Wowzer

    that table basically shows what is commanded/calculated based on the timing tables and the min/max limits from additional tables. so, based on rpm and manifold pressure that is what the ecu is wanting for timing.

    Wowzer how do I determine whether the negative 14 degrees I have set at 5000 rpm and 18 psi on my advance from map warm full graph line point actually is plus 3 degrees.
