Not exactly, it would turn off at an engine off stoplight then too. It was noted that with the key off, cars were looking to the guino like the injector was stuck open. So if the injector is open for a "rediculously" long (1.5 seconds) time then we start the clock on the LED Backlight shutdown, and eventually the part where we (will) reset the current trip and write the tank and other trips to permanent memory, after several minutes (5?).

Constant power will become necessary once once the "save the tank/trip data and reset the current trip 5 minutes after the car is turned off" logic is written, yes.
