Saw these data logger chips at Sears - for $99 you get a chip that clips onto the OBD2 connector, records data for up to 75 hours- plus a PC software package for data analysis. My questions:
1) is this worth the price? 2) Once I have the data, how do I know what to do with it? 3) Do I then need another $200 worth of shop manuals & tech data? 4) Will my 2 later model cars ('98 acura Integra, '98 VW Cabrio) work with it?Any feedback woul be much appreciated.
