02 Sensor Install - Much Appriciate Your Help

[koduRB25det]

Guys,

I got r33 S2 and recently got a o2 sensor from ebay.

http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...E:X:RTQ:AU:1123

it dosent comes with the sensor. instruction says connect it to the signal wire from the standed 02 sensor. any one did like this b4 and how is the readings accuracy. thanks

yeah i bought autometer gauge years ago and it turned out to be quite annoying because the standard sensor has such a varying output. changes from rich/lean/rich every couple seconds so you have a gauge flickering back and forth all the time except when hard on the throttle or decelerating. a wideband o2 sensor is meant to be the cure. search wideband and should put you in the right direction but you can pick up the o2 wire for the time being but it wont really show you what. theres prob vids on youtube of both types

return it and spend the money on a carton of piss, much better investment

Even with a wideband sensor, the gauge will still flicker, because that's the way O2 sensors work. Except when you are hard on the throttle - gauge should read full rich- or decell, when gauge will read ultra lean.

they are good if you like flashy lights, etc. also good for checking that your o2 sensor is working and not making you get poor fuel economy.

other than that, they serve no real purpose in tuning, etc as they work off (and are designed for) a narrow band o2 sensor. a wideband o2 sensor won't flicker much when cruising, etc, because what it classes as narrow and lean is a much bigger difference than a narrow band o2 sensor. narrow band works with roughly 14:1 as rich, 15:1 as lean. wide band will go down to about 10:1 for rich and up to about 20:1 for lean i think.
