nothing wrong with your idea at all. the only problem is your limited to what the obd monitors & can you split obd to mutiple gauges.. I don't know about the sho, but the chally doesn't monitor oil pressure. wideband afr, or egt. now all those require hitting the engine somewhere to get the readings, so are more expensive to install. i really like the wideband afr as it immediately tells me if air/fuel mixture is right. egt I like as it measures engine temp. on my obd it's got some info like air input temp/ coolant temp, boost, things like fuel trim by bank. load rating , torque. my chally actually has a setting to show oil pressure the only problem in that mode can't surf the sirius stations, i like my toons a lot. really like the way todd did his aeroforce off the column. if money was no object would do the wideband afr, egt & an aeroforce in chris pod & another aeroforce like todd did his. but the thing i don't know is if you can split the obd to multiple devices, this is what the plx was doing, but saw a couple bad reviews & just to many boxes to make it work. choices/choices just stay away from prosport evos. like i said dynamite gauge at night time.
