Ahh, I did miss that part. In that case tweak away until you get it perfect. The good EFI systems allow total control over the ignition. Does FAST have a start retard function? The Holley setup has another screen for starting. I think with FAST you just put less timing in if the RPM is less than 500 rpm. That way you can run 20+ degrees of initial timing but only have 12 or 15 while starting. See if you have that option in your software.
I wouldn't worry about putting a lot of total advance in for cruise conditions. If the manifold pressure is low (high vacuum) then you can run more than 50 degrees of total advance. When the manifold vacuum gets close to atmosphere (WOT) then you need to pull the timing back to the low 30 range. But that is easy to do with EFI, just fill out those top rows in the low 30's and then put 45 or 50 in the bottom rows and then just smooth it out. Put 10 or 15 in the left column for starting and you should be really close to done.
