Yea that is coolant temp. The top-right figure is the engine load. It's very easy to set up, can just plug it in and it will work. You can configure some more bits for the trip computer stuff but I havent really used that yet as I have the on-board trip computer. The only annoying thing is that you cant really use the little parcel shelf draw thing next to steering wheel as it wont shut when its plugged in, but I might modify mine so it does.
