OK, I found the red "X" on the 3D scale. When the MS manual says to generally tune for "lowest MAP", are they referring to the 3D graph.... or Manifold Air Pressure? I tuned it to lowest manifold air pressure in about 3 bins and burned those. The idle is now very smooth from 650-1100 rpms and AFR is generally around 13.5, so it was cycling up and down because it was lean.

What I don't yet understand is why the EGO correction is above 100% - sometimes 170% and why the VE values that I've now saved are not evenly interpolated between bins.

I need to deal with the oil leak before I go much further. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
