That is a G1 based ecu. It is about 20 years old. Im pretty sure all the Integralink ECU's were laptop tunable but you will need a "Serial Link" box and either a laptop with a serial port or a USB>serial adapter.
You will find a manual for it in the G1 section of the forum here: http://forums.linkecu.com/applications/core/interface/file/attachment.php?id=2527.
Tuning software is on the Link website, PC Link V2.5.
There will not be many tuners around that are interested in tuning them anymore so you will probably have to shop around.
