Depending on your ecu and ecu's startup abilities you can overcome this. If I remember correctly Flash Pro doesn't have cranking fuel/ignition tables based on coolant temperature, only rpm and load?

there's a air temperature fuel compensation cranking table and a water temperature fuel compensation cranking table. the base maps don't pull too much fuel from the air temperature fuel compensation cranking table but they pull a ton of fuel from the water temperature fuel compensation cranking table.
what i do is highlight the entire water temperature fuel compensation cranking table and add back some fuel till the car starts great when warm. then just double check the next day when the car is cold.

For my AEM series 1, here's my cold start settings. When I drove to Minnesota earlier this year, it started just fine in -4 degree winter weather. E85 needs more fuel to start in cold weather so the tune needs to be adjusted. Every car is different so it will need some tweaking with. I pretty much copied what I found on EvolutionM.net and messed a tad with it.
Thinking of giving it a try.
