If I'm not mistaken on some models the gauge that in our E30s is the MPG is used for oil temperature instead. Does anyone know if that's a relatively easy swap or if I'm going to have to get a seperate gauge?

it has nothing to do with the "gas pedal," which isn't a gas pedal anyway, it's a throttle. the "gas" is controlled by the ECU, not your foot. Most of our cars aren't carburated! ;)
I'd much rather have an oil temp ala the M3. The fuel economy gage was neat at first, but it quickly got old. I always average 21-22mpg, it doesn't seem to matter how I drive the car.

If you don't have a suitable place to fit the M3 sender unit, then just screw it in place of your sump plug. It's exactly the same thread, and seals with the same sized crush washer.
If you look on the back of the M3 cluster, you will see a three pin connector (has 3 spade style connections). One is marked '+', another is marked 'G', and the last one is not marked at all, but it goes to chassis GND. The '+' is pretty obvious and goes to a suitable ignition controlled 12v supply, and the last one 'G' goes to the sender unit.
Easy :D
