ive been using winaldl for scanning the 1227302 with the software for the 122170 in the fiero. so far from what i can tell the readout looks to be dead on. does anyone have any idea if there is a compatability issue ?? ive checked the info against a otc tech 2 and its the same data on the same lines. so if you have a 3rdgen f body with a 2.8 v6 and a 302 ecu feel free to scan with winaldl i guess. in winaldl its the 1985 mpfi setting.
