yeah I know a wideband is the best thing to have, but I am on summer vacation and Cheap thrills are the best. I have been reading several articles on how to make a narrow band o2 sensor display. Basically this one

Yes the parts were super cheap o2 sensor cost more then the electronics. I am having problems adjusting the LEDs. Anyone a electronics wizard?

A narrowband display isn't going to tell you anything more than a narrowband sensor will....which is nearly nothing. All it will do is show that the narrowband is switching.

its more of a project then to tune the car. I am a high school teacher in California. Its summer time and to da# hot to work on my car. So I figured I would make something inside in the A/C that seemed pretty neat.
