Look/search for the 2 transistor interface. It is used to convert from the TTL ECM levels to RS-232 levels the serial port on the laptop uses.

Then search for Moates software. It is the stuff to run on the laptop to collect the data. There are other free programs out there too.

Check out/search the DIY PROM board on this site. Lots of good into there. Your ECM is the same one used in the '90 to '92 TPI cars. Different data stream though.
