The DS 708 hardware wise is more than capable of handling simple recoding Pinion Factor / revs per mile editing that the older slower OE scan tools like the Chrysler DRBIII, Ford NGS, and GM Tech 2 can perform.
Here in the USA we have lots and lots of Not Too Bright Clowns and Posers that wish to project a Easy Rider, Cowboy, Gangsta Rapper, and East LA Thug Wannabee image that insist on putting oversize or undersize custom wheels on their vehicles and we need this feature on our scan tools to insure we can separate these fools from their money and have the vehicles leave with correctly working speedometers.
