RE: speed limiter

[Tim Irwin <timi@Interlinq.com>]

True, and I may get called on it if I campaigned nationally (little chance
of that). As you may have seen on earlier posts, I intend to follow the
rules quite closely. However, this would be a modification with no effect
whatsoever on the speeds seen in Autocross (<70MPH), and I could argue that
there is nothing in the rules that disallows such a modification (engine
timing changes as done by A/M chips are specifically disallowed in some
classes). Similarly, the euro headlights -- which I would like to get when I
have the money -- could be considered a modification, but would have no
effect on performance.

While either change _could_ be technically illegal, I don't see how they
would conflict with the spirit of the rules, which would be to disallow any
change which would either enhance performance or deny a manufacture's
advertising/identity (i.e. de-badging). In my mind this is a different case
than a change which could be concealed well enough not to be discovered, but
would enhance performance.

It is probably a moot point anyway, as I would be amazed if they were
willing to make the change (though I can argue it from a safety point of
view, and I know the owner of the dealership is familiar with SIR as he
races a vintage Porsche 917).

As a side discussion, I know that several of the BMW tuners use the ODBII
port to re-program the stock chip. Does anyone know why none of the VW
tuners do the same?

Just playing devil's advocate but even if the dealer could alter the chip,
wouldn't it still be considered a modified chip as far as the rules go ?
Technically it would no longer be a stock chip found in normal production
vehicles.
