Retain ECU power with kill switch
 

Hey all, setting up a 2018 86 for endurance racing. Wondering how everyone sets up their kill switches.

With enduro we have to flip the kill switch each time we pit to refuel, because of this my understanding is the ECU would need to relearn engine parameters if it loses power as well. Is there a known way to kill power to everything else but keep power to the ECU so it retains its memory?

Thanks!

The ECU also serves as power distribution for low voltage sensors, so those are still going to be powered to.

I think the standby current would be much higher if that were the case. Not sure, though. Always ready for a surprise.

What is the normal standby current?

like 5 mA
