I puttered with an interface to connect a mini-itx computer to the OBD-II. I managed to do $1909 in damage to the wiring of my 1999 Police Interceptor. So, the first task would be getting someone to design an interface to the OBD-II, and then formatting it for the cfontz display should be a piece of cake.
I just sent my board files to the proto shop for such a device. It uses a 2x20 lcd and can interface with all 4 OBD formats. I should have it built and working in about two weeks. I'll post a pic and details when done.
They have THREE versions of the chip..you must know which one you have on the car!
You can buy the Board with chip and cable! And you can get a kit of the chip and crystal....using this you make a Pc board with the ELM and Stamp..and the connector for the cable(26pin serial)
a dual connection to the Rs232 in/outputs on the ELF gives you a output for a laptop,I,m thinking of a stamp feed,so one can change the Info sent to the Display! the idea of the setup is to get rid of the laptop when you are using the device!
connect this to a Stamp II using the GPS program (NOV 03)
Nuts & volts..or get the last volume book!
Modifying the software for the stamp gets you a display via a serial port! .....You can download Data sheets of all three from the data area! the software for the laptop is limited(Beta)
