I've read some old threads on this, and it seems like the current flashscan and V8 software was supposed to have this functionality. will my V2 scan older OBDI vehicles? 93 vortec V6 S-10 Blazer, to be specific... In my younger, dumber days, I would have just plugged it in and tried it, but now I know better than to stick something that I'm not sure of.
