obd 1 software
Can anyone recommend software for the 3.3l gm cars from 1989 to 1993 using the obd 1 computer system. I have the usb cable and have used freescan. It works, but gives you little data. I want to see things like sensors live and be able to download history. What is available for free and for sale. I don't mind paying for it, as I have 3 of these cars. Thanks, Ken
