a regular arduino board will work. Looking at the OBD schematic, it should overlay perfectly with the mpguino, hardware-wise, as there is no conflict between OBD's use of TX/RX pins, and MPG's use of Injector/VSS inputs.
If you intend to dual-function the arduino, you will definitely need a 328 chip. 168 has too little memory. Also, to reduce pin usage for other functions, you could buy a 74hc164 chip for $.50, to allocate 3 fewer digital i/o pins to the LCD.
