Does anyone know how the speed limiter works, or if it only applies to
certain performance models (such as the S-cars) only? Someone mentioned
having their speed limiter disabled earlier and Bob Myers and I have had
similar discussions.

The reason I ask is, I once saw an indicated 140 mph in my '92 100CS 5-spd
non-q while running 205/60VR/15's (instead of the stock 195/65HR/15's). Bob
Myers has pointed out that the rolling diameter of the 205/60's is larger
than the 195/65's, so I should be traveling faster than the indicated speed
(speedometer error notwithstanding). How is this possible if there is a
speed limiter? I have the silly "130 mph max due to tire limitations"
sticker on my dash, but it does not specify a speed limiter. Anyone have
any clues?

Ned Ritchie has the info on removing the speed limiter for S4/S6 cars on his
site; not sure if that applies to non-20vt motronic cars...
