I got Roberts cable in and tested on my 91 caprice with no issues.
However TP will not connect to my 88 fiero.
Fiero is running the stock 7170 and AKYM,only change is deleted EGR.
My Tech 1 connects immediately with no issues,but TP just keeps saying (connecting...).
TP finds the cable just fine,so wondering what the issue is.

I'm using $24.ads imported/converted to .adx .
I'm sure i'm doing something wrong,just not sure what.
Any suggestions?
I have tried with the switch in both positions and nothing,assuming it shouldn't take more than 5m to connect.
