The engine ECU interface for the 1st generation Mitsubishis is refered to as OBD-1 in most DSM crowds. I also have a 1996 Eclipse GST. So I have included both OBD-1 and OBD-2 resources here. I will add the OBD2 port diagram if I can find it.
I have decided to go with a Pocketlogger setup. There are links for pc datalogging, but most of this page is dedicated to the palm pilot datalogger.
(Looking straight into the diagnostic port. The codes to the right are some of the connector numbers in the shop manual.)
|1 - ECU Diagnosis Output|
|2 - Unused|
3 - Unused
|4 - Unused|

|7 - Unused|
|8 - Unused|
|9 - Unused|
|10 - Diagnosis Control Signal (Diag On/Off)|

Most Mitsubishi and Hyundai pre-OBD-2 cars use this port layout.

I have not purchased the interface cable (this is the most expensive part in most cases.) I will add more information when I make this move. For now, here are the most helpful links I have found for Import datalogging.

Here is another great option that costs more. I have not heard any reviews of it compared to other piggyback systems. But it seems to be one of the best options. Especially once they get "knock-logging" added to it.
