View Full Version : lumenition Lambda Sensor Wires
Anyone help, if i can not get a new gauge does anyone know what the three wires that go to the lumenition Lambda Sensor are, what colour is what?
Thanks.
If you have a link to a setup or instructions that would be great also as i can not find mine.
From what?
The 3 wires will be 12v, ground, and signal wire.
If it only displays ~stoich' values, you'd be better off saving your money.

I know what the three wires are but do you know which colour is what?
Can i ask what is ~stoich' values?
Not when I don't know the equipment it's connected to...
Stoichiometric afr value: 14.7 - If the gauge only reads a digit or so either side of that, it's not gonna tell you anything worth while.

Its a Lumenition Lambda Sensor with a three pin plug.
As for the gauge do you have any recomendations?
No issue just found out what the wires are in reference to what colour does what so thanks.
Still interested in if anyone has a gauge they can recommend?
Ahh, I thought you meant you were trying to hook up the gauge to something like an LM-1, AEM, Zeitronix, etc.
If it's a 3-wire sensor, don't waste your time fitting it, as that will only be a narrowband sensor.
Any decent 0-5v wideband gauge will be fine, but you'll need something inline to control the sensor/read the data & give an output to a gauge. Cue the aforementioned items.

Its already fitted its the gauge thats packed up, thanks for the list, i have been looking at the LM1 and see there is now a LM2 for around the same money is the LM2 worth getting ahead of the LM1?
Yes, but that won't give a wideband output, only narrowband (~stoich'), hence will be of no use if you're planning on tweaking your carb.
Can't comment on the LM-2, but I've had my LM-1 pretty much since they first came on the market & it's a great piece of kit.

With the LM1 do i just replace the probe with the LM1 version and then plug the LM1 into a 12 volt supply and plug the lambda sensor to the LM1 and away you go?
Aii, pretty much, except the wideband sensor (which will come with the LM-1, LM-2, LC-1, etc) won't screw into where the narrowband sensor was, as the w/b sensor is a larger diameter.

Ok i could grind the other off and drill the hole and weld the new one on no worries, does the wideband ones also have four wires instead of three?
5 or 6 wires on most w/b sensors.
OK thaks so my narrow band sensor is rubbish then, thanks.
For helping tweak carb's, yes.

That's what i wanted it for, so is the LM range better to own then a setup with mounted gauge off ebay?
So with a 5 wire setup could this be wired into a universal gauge of my choice as i have seen one i like the look of, what is the five wires output for do you know?
