I believe that some newer cars are starting to design them in but they will be even more expensive to buy than the Bosch jobbies sold on eBay like this one
As a matter of interest, you say that you just need the sensor - what controller have you got?

its my ecu iam using its a (link), i can switch between narrow and wide band, it has a auto tune feature you can use both sort of sensors but i think the narrow band is way off. that sensors cheap the only one i could find was 90 odd quid

You'll still need a controller, I don't think that ECU has built-in capability to read directly from a sensor.

You need to get something like a Innovate LC-1

Megasquirt reads directly from a LAMBDA does it not?

Meerkat man,

Not as far as I know! (and I've got one).

Might be a feature of the MSnSE or one of the very new versions, but my MS II v3.0 most certainly required a controller (LC-1 in my case)


EDIT: Unless you mean a narrow-band in which case, yes it should work directly with the ECU (although I wouldn't use that for autotune!)

got me thinking now lol, in my manual it doesnt say i need a controller for the wide band, it just says change the program from narrow to wide . ill have to have a good read of it tonight.

Have a look on here for sensors.

Adam, check to see if your ECU (you haven't named it yet) has a calibration function - these things are absolutely useless without it. My MBE still requires a controller (I have the LC-1 too) to produce a calibrated signal which it can use in a live map. It will however take a narrowband output directly and you can vary the amount of correction in the software.

You need a controller to work with a wideband lambda, they need calibrating and their heater needs full-time control to maintain the correct operating range, this is what the LC-1 does. The MS does not have the ability to drive this. Operating the wideband sensor without its heater will rapidly trash it. Other aftermarket ECU's may do (though I dont know of any, most assume you have the LC-1 style controller and are just feeding the 0-5v signal in), but they'd need 5 specific wires to connect to the sensor, not just the one of a narrowband and a software tweak.
