air/fuel ratio gauge help

[douwboy]

I recently got a air/fuel ratio gauge installed and it is reading over to the fuel side of the gauge all the time on full. The gauge has been installed by a proper mechanic and wired up as per the instructions using the 4 wires of the o2 sensor. If my o2 sensor is faulty would it be a fair indication that it would make the gauge read incorrectly as well?

Did it need to be calibrated?

 

[douwboy]

Its says nothing in the instruction manual about calibration so im assuming it doesn't need it. It is an electronic one.

Ive sent an email away to the people who made the gauge hopefully they can shed some light, just thought id post it up here just incase someone knew anything. The gauge is a iridium series drift gauge.

Not sure how it can read from ~12.2-17.2 from a narrowband sensor...

Does it mention that it needs a wideband sensor to work?

Here are the instructions that i have. I havent looked at any wiring in the car yet because i have no clue as to which wires go where.
The four wire diagram is the one that they used.

My inovate one wasnt that hard, ive read you instructions and even i dont understand them , sugest you email the company.

Yeah I've done that I'm just waiting till they reply back. There is also a autobahn down the road that stock these and they have a workshop connected so I will ask them next if they can sort out the problem.

I was under the impression that air/fuel ratio gauges need a wide band sensor to work.

I never got mine to work, I put this down to the lack of wide band.

Sorry dude, but take that piece of junk back. Your wideband sensor AFAIK will only give a reading under or above stoich, It's utterly useless. It'll go rich, lean, rich lean, not handy.

Do yourself a favour and buy one of these

They come with the sensor, wiring EVERYTHING, all you do is give it 12+ and earth. Oh and you'll need another bung put in the exhaust. That's a true wideband which can also be used for tuning. Very handy tool, mine has been great.

Not if you buy a narrowband one! which this guy has purchased. Actually harder to install then the wideband and alot more useless.

Thanx for your input.

I have the PLX DM-6 AFR combo pack. Recommended.

I considered an Innovate mtx-l or something from wbo2.com but the price on that AEM is great. Definite contender. Accurate Paul?
