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?

it has a cranking fuel table based on rpm and load but it doesn't work too well. the first time i tuned a car on e85 with flashpro i messed with the cranking fuel table and it didn't do much.

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.

I pretty much copied what I found on EvolutionM.net and messed a tad with it.
