my one and only o2 sensor didnt work because my preheater had a short somewhere in the wireing so i had my ecu chipped 2 remove it and i run on none. (now the tricky part) so i want to boost soon but would like to have an a/f gauge can i hook up a one wire o2 sensor like off of a crx and hook that wire directly to the gauges signal wire and get a reading or would it have to be going to the ecu and be spliced into to get a signal lemme know if yall have done this or if it will work please!

 

You need a wideband oxygen sensor.

What is a wideband oxygen sensor?
A wideband oxygen sensor is a sensor which allows you to monitor parts air to fuel. Most people have the preconception that a basic autometer air/fuel guage using the stock oxygen sensor in their vehicle will give them all the information they need about being in a lean or rich condition. This information is false, the factory narrowband oxygen sensor will not provide you with an accurate reading because the oxygen sensor is a narrowband sensor which does not have a wide enough of a range to accurately sense air/fuel mixtures needed to properly tune a vehicle. The purchase of a wideband oxygen sensor is not required due to the fact that almost every tuner provides one with his services etc.

 

Thanks for the info and i am going to buy a wideband but the ? is still bugging me would it work?

 

On your boosted ecu program, you can simply disable o2 sensor feedback which would enable you to run no oxygen sensor at all.
