It's not so complicated to get serial LCD working with MPGuino with basic functionality. But it requires lots of changes to the code though.
Much easier and quicker way will be getting a parallel LCD.
Using serial LCD has one big advantage over parallel setup. It leaves you lot's of free pins for other interesting functionalities you may embed into MPGuino. Like MPG sensitive cruise control, for example.
