So I live in an apartment complex currently, and I bought a tune for my audi Q5. I also just bought a battery charger since I don’t want to risk messing up my ECU.

I for some reason figured I’d be able to charge the battery charger, unplug it after some time, then just use it portably. I was wrong. It needs to be plugged in to use.

So if you were in my shoes, where would you flash your ECU? Are there known places that have power outlets near places to park?
