I'm looking at a piggyback computer for my Subaru WRX's ECU. You use a notebook or Palm running Hyperterminal (or similar program if you prefer) to interface with it. It's how you tune the computer for performance, but you can also use hyperterminal to do a "digial dashboard" which shows you tons of data on your car.

They say this UTEC interface is opensource because they'd like someone to come around and make a pretty interface to replace the Hyperterminal. How realistic would it be to have the empeg display some of this info like Exhaust Gas Temperature, Air Fuel Temperature, etc etc?

Would be nice to use that little serial connector hanging off the back of my sled . I can get more information if it would help answer this question.
