Using the demo version of ClimaSim, I can't mess with too many parameters, but theoretically, here are the changes from earth:
Eccentricity = 0.1, so significantly higher than earth
Semimajor Axis = .86 AU (but it's orbiting a star that is only 0.91 solar masses, so in terms of effect on climate this comes close to a wash, plus I couldn't see a place to change the solar parameters, at least in the demo version)
Day length = 22 hours, but again I can't adjust that in the Demo version
CO2 partial pressure is equal to earth
Axial tilt, I left the same, but I may play around with that some more if I don't like the result

All of this resulted in a slightly higher average global temperature at 19.44 C (I think), which is almost exactly what I calculated after accounting for the SMA and Solar density difference (292.48 K ~ 19.3 C), so I'm not too concerned about leaving the number at 1 AU for the SMA for the purpose of the simulation.
