I was talking to someone the other day and I think they were blowing smoke, but I wanted to check with the pros just in case. They were telling me that there is a module of sorts that you can get for the Z series that will take multiple gauge inputs and display it on the screen. He said that it had multiple inputs for oil pressure, oil temp, water temp, etc.
I can't find anything online at all so I'm thinking its a bunch of BS... but it would be awesome if it did exist!
