Doesn't it end up being a big hassle if you keep using the security map, then reloading a performance map and letting it relearn again? I guess if you also reflas the real time should be ok.thanks. i never left the version one AP i had for my forester in the car. i want to use the security map on my wrx so i see no way around leaving it in the car. it isn't like there is a built in battery in it.
