Excellent work. So did you find the current draw to be the same (or close to) regardless of the tool being in the port? Perhaps Gap has addressed it. Thinking about it, their advice re this was quite some time ago. Anyway, I still felt it prudent to minimise its use with the vehicle off but what you’ve found gives some comfort.

Cheers,

I couldn't detect any additional current draw when the car was asleep. I've been meaning to check if the OBD port has constant power or if it comes off one of the switched ECU power busses, but I'm still missing the round tuit required to make that happen.

if you leave the Bluetooth connected it absolutely stops the car going to sleep though.
