No idea what settings you're using. You should start low and work your way up .2 at a time until it starts reliably at that temp.
If it pops and backfires then you're flooding it and you need to lower the amount of fuel. If you flood it you'll have to wait for the plugs to dry to get it started again.
Have fun.

I am not that familiar with the megasquirt but I know with my Link I had a simalar issue that was cured by reducing the prime duration.

what size injectors are you using... and post your cranking setting page please. we might be able to give you a closer number to start with.
