why cant you hook a autometer a/f gauge to a wideband o2? like to know why this is.

 

the autometer a/f gauge operates from 0 to 1 volt for the signal input.

at typical widband sensor operates from 0 to 3.5 volts or sometimes more depending on the sensor.

it will not work period.

 

how do you know if its a wideband sensor

 

most if not all honda's use normal narrow band o2 sensors (0-1volt)

 

how many wires

 

mine is a denso 4 wire

 

Wideband sensor dont output the voltage themselves either you need a controller box, some controller boxes however do output 0-1v but who the hell wants to guess if a green light means they have the right AFR.

 

so there not accurate

 

what should i use

 

Good widebands have a second 0-1v output that you could attach your autometer A/F gauge too. It wouldnt have as much resolution as the full 5v output tho.

 

resolution. do these gauges serve a purpose or not. i just wann know if the close. im getting my car tuned anyways but i just wann know if my car leans out.

 

For tuning purposes, no they do not serve a purpose. Example:

Let's say you're in boost, and your AFR is 13.5:1 On a narrowband A/F gauge, this is going to show rich as pretty green LED's. When in fact, you are too lean for boost and will blow up.

The narrowband gauge pretty much just shows you when you are in closed loop or open loop.

 

Those gauges are just little light displays.. And a wideband sensor is nothing, its the controller box for the sensor that does everything..

 

so should i get tuned and not worry about it, or is there a possibility for the tune to change

 

The AF ratio varies the most with temperature changes. Most editing software out is now including correction for this, but other things can change it as well.

Personally, I'd get a wideband so you can keep an eye on what AFR is at all times so if it starts to get too lean or too rich you'll catch it before you do any damage.

You don't HAVE to, but most here would recommend it.

 

im running uberdata so does this mean ill have to keep retuning or should i use something different

 

does the air fuel ratio on the apexi turbo timer work well, is it close to a wideband?

 

The only thing close to wideband is wideband.. There is narrowband and wideband.. Any narrowband no matter the company cannot be used for tuning at all..

Uber has temperature change correction in it, so it the tune should remain the same with slight fluctuations.

heres a product I just found that will do what you want; but you will have to buy the wideband controller as well

 

you could get a wideband like the plx m300, and hook the narrowband output up to the a/f gauge.

 

their was some one that moded the autometer a/f gauge to read from 5v to 1v
