Do you just load up a base map (or come up with one on your own based on your experience), get AFR and timing values to good levels as quickly as possible and than continue with the break in of the motor? Or do you use some other methodology?

Myself personally I have enough base maps that I can have the car running/idleing/reving like normal/stock within 10 minutes, 99% of the time the car will be idling good and running great by the time the coolant gets to operating temperature.


Hannibal's suggestion is a good method to make sure the car starts okay if you don't trust yourself or don't have enough experience to get the car running clean on your first try.
