I am unable to connect. I originally had no problems...then intermittant ..now I cant even connect.

I tried emailing Chris last week...but no reply yet.

I have checked the settings...and configured them as in the instructions. I even tried other settings...no good.

I have power to the Diagnostic link as....the instructions say I have.

I tried a continuity test......all but one wire from the ALDL to the serial plug has continuity. Is this the way it is supposed to be? Do I have a bad cable.

If someone can do a quick continuity check it would be greatly appreciated.

Could a bad ECM cause a connection problem?.....I have real bad surge problems...that some good tuners cannot figure out...I can watch the throttle bladerhythmically open and close 1/4 at idle ...(I have a 98 vette with electronic throttle controll (fly by wire).


Please all advice is welcome......
