How could I make a throttle position gauge? An example of what I am thinking of can be seen here - http://members.optushome.com.au/ozfb...lie/inter.html - its the fourth pic down, the little light bar above the steering column. Any ideas on how this could be done?

Use a T.P.S. Throttle position sensor
from a fuel injection system and a LED bar graph display and driver (Radio Shack)

It's called kinesthetic sense of where your right foot is.

Damn, Willie. I thought I liked the doo-dads... I bet you don't even need a scanner anymore. That's the coolest part about his setup though, guys: you can't buy that stuff. I'm totally all over stuff you make yourself.

Here's a 3 page schematic that includes a TPS bargraph readout, A/C cutout @ WOT, NOS enable @ WOT, and O2 sensor bargraph readout circuits.
