Alright, someone explain this to me.
A wideband 02 sensor (like a bosch from a lean-burn honda) outputs a voltage from 0-5v, according to the air/fuel ratio in the location of the sensor.
Can someone please tell me why you can't buy the 60 dollar sensor and a voltmeter? Why the need for the crazy (and costly) display? Sure, it's more convinient, but as a tuning tool, surely you can do some simple math such as "Ok, 14:1 is 2.5v, so let's shoot for a 2.5v output on this pull"?
