I'm guessing that you are trying to install an old Shiftmaster EEC tuner and having trouble getting your laptop computer to communicate with the chip. Does the car start and run okay with chip attached ? What year is the car, what version EEC tuner (some versions didn't work well and had to be returned and reflashed). Usually when the connection is bad a bunch of lights on the dash come on and the cooling fan turns on and car won't start.
When I had one it was very difficult to get a good connection at the access port because the contacts on the tuner were very flimsy and didn't clamp down very well on the EEC circut board. I had to clean mine off about 3 times to get good contact.
You are not going to get much help here, because almost no one uses that to tune their car. Dave Dalke and Fraser are about the only people here who know enough about them to help.
