A/F gauge second question. I have an extra O2 sensor that has 4 wires (not installed yet)would it be better to hook up an A/F gauge to that O2 sensor to one of the 2 wires that get grounded.

4 wires on a O2 a/f gauge???? never seen one of these, unless one of them is for the backlight.
He might have the Wideband O2 sensor. THe most accurate one is the O2 sensor with 5 wires that Turbo guys usually use to manage their A/F ratio to the exact decimal. A lot of VW guys i know use a WIde band.Originally Posted by Magny
Even K&N makes these with 3 wires running off of the O2 sensor.
Even tho the Aftermarket A/F gauge is said to be inaccurate, for a N/A motor like ours without crazy ass mods and high revs past the stock, it is perfect to find the stoich and lean and rich.
I know how to convert a new honda 4 wire to a old honda 1 wire style and I happen to have one around my house. I was wondering if I should use it.
why not just use our reg stock O2 sensor? The 4wire might do something crazy or its calibration might be different, i dont know. The VW guy i was talking about uses the wideband as just the sensor for the A/F gauge not as a sender for the ECU.
I was just wondering if it would be a better signal eventually I plan on converting to 2, 4 wire models with preheaters.
how about test out the new O2 sensors and see if it puts out the voltage as the stock one with the multimeter. The shop manual has a page in it where it shows how much voltage it should put out at idle and some high rpm i dont remember.
It should read above 0.6 volts ay 5000 rpm and below 0.4 volts when throttle is released.
I would not be the first one to do this also When I read about how to do it on a lude page the guy mentioned that his A/f Meter reacted a lot more quickly after the conversion
Yeah, cuz u both are using the wideband O2 sensors thats why the lude guy felt his A/F gauge respond much quicker. Also from what i heard, these Wideband sensors can run an up of $400+ off the shelf (Not ebay price). I would love to get my hands on one, but i dont know if we can use this sensor as an input for out ecu, from what i believe they can be used only for monitoring. i dont know for sure tho. :cool2:
