RE: Speed Limiter (no Audi)

["Dan Sinclair" <sinclair@prospro.com>]

Another interesting side note:  My brother is a professional truck driver
and bought a used 1993 fleet Peterbilt truck with the standard Caterpillar
6cyl.  When he took it in for engine work, the Caterpillar mechanic asked if
he'd like "the governor limit moved".  The mechanic told him it was
presently set to 70mph (at the request of the previous driver's employer).
My brother said "sure, take it up to 85".  The mechanic pulled out a Compaq
Pentium laptop, hooked a serial cable to the trucks 'ECU' essentially,
dialed in 85 in the software, hit enter and unplugged it - all done.  Now
that's a diagnostic tool with some functionality!

Ooops.  I just read that the A4 has a fly by wire throttle and cruise
control.  I suspect you're right the speed limiter is an extension of the
this instead of a wrapper around the rev limiter. This would also make it
safe to hit the speed limiter regularly. Changing the speed limiter is likly
only a software change (probably reqiuring lots of reverse engineering, or a
shop that has done that, involving many legal issues, etc).
