Carl,
In this case it is a NA 300zx, not a turbo so I guess the ECU would only
modify the "fuel maps & timing maps, plus removal of the
155MPH speed limiter ". I doubt it would ever make 155. Especially at an
autoX event ;-)
So it sounds like it is legal for ESP to change it in this case.
Tanks for the information.
