What are some potential settings changes that I can play around with in the tuner software to decrease the amount of time the car needs to crank before starting? It takes around 3-5 seconds versus less than a second stock. This is at any temperature and I always let the fuel pump prime completely before starting.

I'm assuming it's related to the injector settings. I am using ID1050X injectors.

 

Are you not tuned? Running on the base map isnt recommended for long term use. But to answer your question, your issue is probably in the Fuel trim at start up. Go to the starting tab and try adjusting the values in the FuelTrim_coolant at the 0 second column
