[duster340]

have been looking around some for an air fuel ratio meter and found this one:

would it bee worth it since its not a wideband sensor?

i know i will have to buy a sending unit for it also but i gues i would bee ok with a universal one is this corect?

will one of these gauges with universal sensor be any good fore some tuning?

i cant realy justify a wideband sensor when i can get the car tuned at a chassies dyno for the same kind of money and i like to tune and work on my own car as much as is possible
thanks

No, those guages only indicate whether you are richer or leaner than schiometric (14:1). You can't really tune with them, you need the wideband meter. They are popular (and I have had them) with folks moding turbo cars because they will show you if you have a dangerous lean condition.
