I have a MXL2 in my '93 RSA, I've added brake pressure, throttle position and steering angle, and it's TONS of info to look at, not to mention shift lights, different display pages, etc. I was lucky enough to be able to turn my OEM oil temp/pressure gage sideways to see it until I add those sensors as well. It's not a cheap buy-in, but it's one-and-done with the ability to add as you go.
