No digital dash here, just a character display. I'd take some pics, but I don't have a digital camera.
On my setup I have it display fuel sys status, engine load%, temperature, fuel trim, RPM, speed and timing. It updates about twice a second. To compensate for the slow update speed it helps to setup a priority system. For example, RPM needs to be updated more often than temperature.
For hardware, I'm using an ELMScan VPW board.
