Cranking setup

#1 · January 18, 2019, 9:52 am

Hi everyone

I've been using my fitech 1200hp for about 600 miles. It's mounted on a mopar BB 400ci stroked 500.

I'd like to get some tips to tune it.

When i come to the car when it's completely cold, and turn key for cranking, the engine starts perfectly, almost immediately. If i put key off, then key on, and crank again, after one start or when it's warm, it takes more time and i have to play with the gas pedal to make it start? I don't really know which parameter to modify and fitech did not give me a lot of good informations.

Do i have to modify cranking parameters related to temperature? Or cylinder temp? or coolant temp?

Thanks for your help!!

Cranking Fuel adjustments are unique to every combination and climate. Trial and error is about the only way to tune this feature. The temperature break points are coolant temp. Her is a link that should help.
