Re: Obd1 live data??
Not many options anymore.
Moates used to make one, very popular back in the day. I think maybe that's still your best hope if you want a pre-built solution. Or there may well be people on the PROM forum that can help you out with it. Seems like there used to be recipes for building something similar on the Internet, if that's within your capabilities; you'd need to have a certain amount of electronic prototype building experience. It needs to be an appropriate cable with the OBD1 connector on the end and a fairly simple data converter from the OBD1 format to RS-232, so you'd have to have a way to then get that protocol into whatever you're wanting to read it with. Probably easiest way these days would be a RS-232 to USB device.
Bear in mind, the rate that the data comes out of that ECU, is something like 190 baud. NOT MBps, NOT Mbps, NOT Mbaud, NOT kbaud; BAUD. Symbols per second. That's almost slow enough that a person could read it and call it out in real time as the ECM puts it out. So keep your expectations low, it's not like anything modern in that regard. Useful enough in a way butt quite limited. Only really adequate for relatively steady-state conditions.
