I have beem using TunerCats for several years to tune my 94Lt1 engine in my 37 Ford. Everything ran good until recently when the motor started stumbling at stop lights. I dug out my laptop and cable to have a look but the TunerCats wanted my registration then would not accept it. All e-mails to tunercat were bounced back. I started up Scan 9495 to have a look but the app will not connect. I had loaned out my ALDL cable and it was lost so I ordered a new one.
Now none of the OBD1 programs will connect to the PCM. Ive changed drivers for the cable and am using 2.12.24.0. Can anyone tell me how to check out the cable? Is there someone who could test the cable for me? I've tried it on two laptops, both running Win 7,

Thanks in advance
