goto google and do a search. i was thinking about buying one too cuz my check engine light's kinda whack. however, the price's kinda high for me personally...that's like going ot the dealer 6x for diagnostic.
I would like to know if anyone on this forum uses the autotap specifically any scan tool that can moniter KR. I have a scan tool, Dan Harrison version and I wish that one could moniter KR. Actually I wish it could do the things that my cousins autotap can, but it's not a bad tool to have, and for the price, worth it.
