It's quite simple on the EUDM version: the tachometer has it's own board with some logic to drive the needle, there is a simple little pcb for the econ/pwr light, and the speedometer is fully mechanical (eddy current drive).
The difference is likely to be in the speedometer, it would be interesting to know if you can connect a chime to the EUDM one, but I dont think you could duplicate it with an arduino easily since you would need a sensor on the speedo, which is not easy to do.
