If that is in fact the case, the system should see a DME file that differs from the factory version, and reject the car as being modified.

An 01 car would have partial CAN Bus technology, the 06 car would make much wider use of CAN Bus to communicate with the DME and all the vehicle control modules as well as the instrument cluster.

JFP do you know if a ROW 996 program in a CA 2000 Boxster would be detected as modified ?

Based upon what I have heard/read, because the smoggers are looking at the DME information and how it compares to a reference file, I would think any RoW tune would be detected, simply because it does not match what they expect to see. All depends upon how accurate their references are, and how closely the DME must match.

As most modern engines are now "fly by wire", even something as small as adjusting engine idle speed for a customer complaining about the engine shaking at a stop light with the AC on requires modifying the computer's parameters. So, will raising the AC on idle speed 50 RPM fail a car? That is the big unknown.........
