Fuel air ratio gauge

[Cru328prod]

Hey im gonna install a Fuel to Air ratio gauge, anyone have any ideas if the O2 sensor is 1 wire or more? If more which one do i plug it into? Or better yet is there a closer wire to the engine bay where i can tap into that wire?

Do you think they are accurate? What kind of boost are you getting at full throttle?

around 7 pounds of boost, stock but a cold air intake, dammit im surprised no one knows this.

was noticing your temp gauge...does it usually run that high since you did your intake? i see it runs almost to the next line up from center...

i'm not sure about C230K whether they are narrow band or wide band O2 sensor. if it's a narrow band, i don't think that the gauge will be accurate. it's more like an on/off switch, which can only tell whether it's lean or rich. previously i install the Autometer AFR gauge, tapping the signal from the o2 sensor and the gauge would just swing back and forth. now i got the innovate LC1 to monitor my AFR and it's working perfectly. I would know exactly what the AF is at, ranging from 10:1 to 20:1 AF, which can be monitor both via the gauge and my laptop.
btw, i using a C220, which have a narrow band O2http://i205.photobucket.com/albums/bb239/toei06/11062007113edit.jpg
