Default Rough start/ flooding issues?

Hey all,

I came back from a track day on Sunday and let my car sit overnight. Monday night, I try to start it up and there's a weak crank, with maybe 1 or 2 cylinders firing, but the motor will not run. Last night, I try again and it fires right up, but misfires BAD, running pig rich. After the motor warmed up, the car ran and idled just fine. I'm running an MSPNP 9093 with everything else stock on the motor. I didn't touch the crank pw from the base map, and it was ~50F outside. This is the first time it's happened to me, so I'm pretty confused what went on. My guess right now is somehow my motor flooded and the plugs wouldn't fire. Wires and plugs have <6000 miles on them. I did not notice smoke from the tailpipe, but it was dark. Has anyone else experienced an issue like this?

DIY didn't tune past 60* on their map. Probably had too much fuel during cranking at that temp level, lower it the value to match the 60*F value and next time it's cold bring the laptop out with you and start adding fuel until it starts.
