If you have a laptop and an ALDL cable ... FYI here's a new application for the '94-95 OBD1 'flash' PCM's, ABS modules, SIR (seatbelt) modules. Plus it has an actuator tab to test fans,air pump, A/C clutch, EGR, EVAP, and IAC idle control. Downdload is in post #2 of this thread, http://www.ls1lt1.com/forum/4th-gen-...gram-free.html latest version works on windows and w/XP. It's new and creator 'garydoug' is open for input, App is geared to emulate a Tech-1/2 service environment. It's not for tuning, or complex data logging. As far as I see it's the only 'free' ABS, SIR scanner around. The actuator testing is a lot better than using jumpers to test things. App assumes the user knows at they are doing, Eg: don't pick A/C clutch w/o refrigerant on a running engine..
