Motronic Spider timing adjustment

[Glenn Wasserman <glennwa@domain.elided>]

I am autocrossing my '93 Spider, and I'd like to know how to advance the
timing. I've never really done it on any car I've had, and I understand I
can get a little more power out of the engine by doing that.

Also, what's the harm in leaving the timing advanced for normal driving?
Should I set it back at the end of the day?

Thanks,
