I just picked up a used Innovate LM-2

http://www.innovatemotorsports.com/products/lm2.php

Doesn't have a ton of channels, but will accept 4 analog inputs, plus RPM and A/F. Will accept voltage signals from electric gauges.

It's pricey new, especially if you need to get the additional transducers, but I got mine on the cheap.

Faster, Faster until the thrill of speed overcomes the fear of death...
