Check out 14point7.com. If your handy with a soldering iron they offer a lot of options to a wide band. You can monitor several things on one gauge. I'm going to have two in my car to monitor the siamised ports.
Can you give me a link specifically to the parts you're talking about because from what I've seen, all they're kits are like $200+.
And what would I need if I simply wanted to monitor the A/F ratio? An O2 sensor and a led display?
