It sounds like you are trying to set up a system that connects to the OI dashboard, parses the data, and then prints it out onto a LCD.
If you are looking at just doing the current angle, why don't you use the 3 number display already on it?
if you still want to do the LCD, I would suggest using a 16f628 and decoding the dashboard data. The specs on the data packets are on IFI's website.
