I want to use my computer, ( PC WinXP ) to monitor the On-Board Info in late model cars. There are so many programs for sale, all making great claims, I have no idea which may be best. I would like a somewhat comprehensive program(s), maybe. PowerTrain info , primarily, but other info too, as Transmission, AirBag, ABS etc. But, I have no idea of prices, usefulness or compatibility items.
Any advice is appreciated.
