Does anybody have a preference for a laptop computer / OBD2 code scanner? I had been looking at the autotap unit [url="http://www.autotap.com"]www.autotap.com[/url] The new ones are now USB rather than RS-232 into the computer since many of the new laptops no longer have external serial connectors. USB is faster anyway. Gives generic data and at additional cost, enhanced data specific to GM shch as transaxle settings. (does this apply to Saturn too?) My son has a similar tool specifically for use with VW and it can set how the door latches lock and unlock (and at what speed). This along with about 200 parameters that no sane user would touch. Good tool though and nice user interface. Thanks for any other recommendations and comments Oppie
