air/fuel ratio
"Easy" or "best"? From my limited knowledge Daryl, the dash mounted displays you can get for under $200 (the "easy") are 1,2, or 3-wire readers only (splice in to O2 line voltage) and they roughly try to tell you the ratio based on voltage. They use a dial or a LED graph to tell you if you are lower than or above 14.7 AFR, but are not accurate to "how much" above or below you are. True a/f ratio tuners use 4 or 5 wire sensors (like the Bosch) that cost around $400+ and tie into several places on the vehicle.
What is it you are trying to do? Tweak something to fool the CPU? Oh, I bet you are going to put bigger injectors on, eh? Most cars with a/f meters are turbos. You wouldn't be puttin' a turbo on that beast now, would you? (grin)
