AFR Gauge that utilises stock wideband sensor

[wild willy]

Does anyone know of a decent AFR gauge that will accept the 0-5v input from the stock LCR wideband Lambda sensor to avoid me having to buy a dedicated gauge with wideband when ours is the same.
Most i've seen only connect to the 0-1v output of a narrow band sensor.

my Scanguage can show afr through OBD. I imagine a liquid gauge would do as well if thats an option?

liqui gauge carl..
multigauge functions also

Hi Guys,
I was looking for more of a dedicated gauge with high data sampling rather than being limited by the poor sampling rates of the ob2 setup.

If you mean wiring a gauge up to the standard Wideband sensor and also leaving it connected to the ECU, i would be careful as you may get false readings to the ECU.

The only reason i say is because the voltage output from the sensor is low (1-5V) and say if the gauge "pulls" a little current to operate (not sure if the do mind) then maybe the reading received at the ecu could be lower than actual.

Not trying to scare monger mate, just not sure if the sensors are capable of running multiple outputs.

Hi mate,
the gauge should get its power from the aux 12v and use the signal voltage as a reference only but i appreciate what your saying. i guess its simpler to just get a dedicated gauge and probe but it would be nice if one was available to use the stocker.
The liquigauge will do fine for the time being.

seperate gauge/probe is what I would do Carl. No chance of controlling lambda being interfered with signal wise (as that in itself would be bad thing)

AEM is a good stand alone & Zeitronix is what I use on badgerwagen for years as it had its own logging output.
