I've permanently mounted the ScanGauge in the dash, with the Coastal RUN/BRAKE/REGEN indicator attached atop it (see the avatar). The ScanGauge is set as follows: TPS, LOD, RPM, and the fourth displayed parameter varies depending on my interest at the time. I don't know how many others here are using that slick gadget, but I'd enjoy comparing information.
I am using it on a 04 for the present time I am doing RPM, Load, GPH, Engine temp. I may change it up. I wish I had a mini scanner or better Atilla's set up! I am still learning, never the less. This car is amazing and I would love to be on the inside.
