This is a simple tuning issue. The combination of IAC Park and cranking fuel are what determines starting AFR. There is also a Fuel Prime adjustment in the System ICF. Fiddle around with those parameters until you get to what it likes. I find cranking fuel values just above fuel table values in the idle area work best for hot start. Then adjust IAC park accordingly. You can also fiddle with cranking spark advance, but I'd leave that as last resort.
