I finally decided to hook up my air fuel gauge and window switch for the nitrous setup. But im having some difficulty finding the oxygen sensor and tachometer/rpm input wire at the ecu. I have an 05 coupe. Any help would be greatly apperciated.

thnx

 

pin 60,61,62 are the signals for cylinder 1,3,5

the o2 sensors are narrow band only, not worth using for their readings will not help you in your need for accurate a/f reading. Most people install a seperate sensor just before the cats.

 

Im just using it as a safty device, not to tune with. I know these things suck, but i needed something to fill up my third pod =). Also how do you get 1 tach signal the 3 different cylinder outputs? I just need a basic tach signal for a rpm window switch.

 

 

you should be able to tap into any ONE of those pins/wires. Each time the cylinder fires it'll send a signal. That should give you the accurate RPM's
