wideband lambda sensors
Turbo Mini Forums

I have fitted a narrow band lambda sensor. This is either lean or rich and flicks between the two.

I want to have a go at polishing my own carb needle and therefore I want to fit a wideband lambda which will give a more progressive output.

Has anyone got got any suggestions for which wideband sensor to get and if possible the wiring.

Have you done a search?

I've had a look on a few web sites but they seem expensive, about 70 quid. I someone knows of one (type of car) that is straight forward to wire up then I'll get one from the scrappers.

Wide bands are expensive.

apart form the sensor (about 80quid) you also need some clever circuitry to interpret the signal, not just a voltage meter like with a a narrow band.

for a wideband set up expect to pay 120quid upwards.

Widebands are nothing like narrowbands.

They require a dedicated contoller to operate the internal heater and convert the output into a suitable voltage range for a display.

Any wideband sensor from a scrappy will only work with the electronics inside the EMS it was designed to work with, and not drive a display.

You might find a wideband LSU (sensor) for £70 or less on the web but without the correct controller it will do nothing.

As Tom says, do a search (on this forum) and you will find various opinions mainly between AEM, Innovate and TechEdge.

None of them are £70.

Schrödinger's cat - so which one am I ???

Thanks for your advice. There's more to it than I thought. I will do some further searching.

Probably worth the cash for an accurate mixture reading.
