This flash is a one off flash that contains all the stable functions of the normal 2.7 V2 flash, but it has a built in long idle function for keeping the truck running on key off, IF and ONLY IF, EGT turbo timer is set to 374*f. The truck will idle until coolant temps come up to whatever your warmup temp is set to, regardless of what EGT's fall to .
This gives you the ablity to start the truck, key off, lock the doors, and let the truck idle, for warmup, while your keys are in you
