OK, I have a couple questions I cannot answer. When I operate my innova OBD reader on my 08, it comes up (accessing but before finishing reading) something 2000. I see the OBD ultragauge mentions ( Keyword Protocol 2000 ), and that it reads 'special functions'? Does whatever reads a Crossfire have to have a reader that uses this KWP-2000 protocol? Second, my model year is an 08, I'm seeing there is a different one for 08 and above. Which ultragauge would read the 'special functions' in my 08 (knowing it is built from a MB SLK-320 drivetrain?), and knowing it is a model year 08 but built in 07. Def do not want to buy one for the wrong model year, its expensive if the wrong car.
