Laptop & cable connect fine to my 91 GMC truck with appropriate bin & adx, but hangs at DA Connecting on my 91 firebird using "AWFU 91 F-car 5.0 TPI 700r4.bin" & trying both "$8D-1227730-V1.1.adx" and "1227730_8D.adx". Both just hang. I find others saying it is probably a mismatch in response packet size, but not sure how to investigate or fix.
