That is very cool! Unfortunately, the form factor is a problem without a decent mount. I notice they sell a multigauge unit called the DM-150, which looks like a GPS device that might be easier to mount on the dash or console, but there aren't any specs on it. Do you know anything about it?I have one of these sitting in a box on the shelf:
PLX Devices Inc. - Multi Gauges, Single Gauges, Sensor Modules, Wideband Air Fuel Ratio, Data Logging, Fuel Saving / Scan Tools
The other problem, as indicated by Greywolf, is that you apparently can only get Oil Temp off the OBD, not oil pressures.
