Nice selection of monitor items. I like the voices of items not normally monitored by in dash gauges. This intake temp, engine oil temp, throttle position , and oil efficiency. I have to disconnect it from OBD as it does not fully shutdown. It will drain the battery if not used. I drive theVette every 1-2 weeks.
