Thanks, I found a site that explains most of what I want to know. http://homepages.ihug.co.nz/~ccgrant/leggymodels.htm

I have a '96 Legacy GT twin turbo imported from japan. I am wanting to find out all the infomation I can about this model. Things like the engine code like MY96 or whatever the Legacy codes are and the ecu type and number etc... Does anyone know or can point me in the right direction? Thanks.

It kind of what i am looking to do, only a bit simpler. My car is a Japanese inport so it did get the obd2 plug and protocol. I have found a couple of sites that sort of have the right infomation, http://www.scoobymonitor.co.uk/ and http://kaele.com/~kashima/car/gc8-e.html . I am sure there must be a way to make a connector so that I can program some software to talk to my ecu.

no I am not sure. It has several plugs under the steering column, 1 of which is green with 12 pins and mounted. I assume that this is the plug that my mechanic connects to read the error codes and get the data from the sensors.

I am looking to make a diagnostic and performance tool. I have a '96 legacy GT but it doesn't have OBD-II. I have read some articles about connecting to the ECU and being able to read error codes and getting sensor information in real time, but they were a bit brief. Does anyone know more about doing this or where I could find more information? I ideally want to build the tool to communicate with my palm pilot.
