[ajdgotskillz]

i just installed two gauges in my car the i have a 2006 nissan sentra ser i put a air fuel ratio gauge and a tachometer the air fuel ratio is hooked up and is alwayz saying that im running rich and the tachometer i was told to buy a tachometer adapter so i bought the autometer 9117 and i tried to install it and the tach wont read correctly when i rev the car up to 3 or 4 grand it will say 1 or 2 on the aftermarket tach need some help dont know what to do???

Regardless of how you wired it, those things are bunk. The signal the car uses is very general. If you really want a proper reading, you should use a wideband sensor/gauge.

Furthermore, you're going to read at least a little on the rich side (or toward the rich side of stoic) because cars are tuned to err on the side of rich rather than blow up.

As for the tach, I have to ask... was your stock tach not good enough? Why on earth would you want/need two anyway? Make sure it's on the RPM signal wire and has a good connection.

yeah im gonna get a wideband air fuel gauge and for the tach its basically for show i just love the way the tinted glowshift gauges look thats why i got another tach.
