I wouldn't worry about the overfill while the engine is running. there's enough gap in the bottom of the engine that you can fill it with all 6-7-8qts necessary and then start the car and fill the accusump without sloshing against the bottom of the crank.

also, the accusump electric valve works as a 1-way valve when you have it powered off. the tank will fill when powered off as the oil pressure builds.

I simply have a switch on the dash for mine and I turn it on during my out lap. I often forget to turn it off post-race, so will cruise around the pits at idle with it on and no problems with excess oil in the engine.

Eventually, I plan to hook that switch to a relay on my AIM dash so it only runs when I'm logging data, but I've been too lazy to do that work. (the AIM is configured so it automatically starts logging when the engine is above 2500RPM and a couple other variables. but essentially any time I'm moving fast enough to need the accusump, the logger is running. therefore it's an easy trigger.
