Can someone just give me some basic info on wideband o2 censors please.

postman

gives a measurment of your air to fuel ratio
example. 14.7 parts of air to 1 part fuel

10.0:1 rich
14.7:1 stoich
20:1 lean

wideband. uses 5 volts, instead of 1 volt. can show afr's ~8:1 to ~20:1
what basic info you looking for?

brent_si

your motor will still need a narrow band output.

So will it be ok if I don't run a wideband?

Depending on your situation. If you have a stock to semi-stock car with a bad O2 sensor and just need to swap it out for a new one, you don't need a wideband. Now if you've got internal modifications and/or a more modified motor with a programmable ECU, then yes a wideband is a good idea. It will allow you to monitor your air to fuel ratios a lot better than the stock narrow band, allowing you to adjust your fuel input to get the best ratio for more power and less chance of detonation due to running lean. Looking at your signature, looks like you could very well benefit from having a wideband, but if you had it tuned by someone that used a wideband during tuning and don’t plan on doing too much more to the motor, then you could probably get by without one. But they are nice to have just to keep a close eye on what’s going on with you motor.

you can use the wideband instead of the narrow band


here's wiring info on it http://causeforalarm.thecarthing.com...ego/index.html
