i told my brother about this app and he went out and got the obd2 blue tooth, so we hooked it up tonight to my car, and we couldn't find any thing for KR, and couldn't get the boost reading, had vac it was 18.6 at a idle, we didn't drive around with it tho. it does have a bunch of good info on it. and my timing was 21 deg's at idle, is that normal?
