For sale 1 x Bosch wideband lambda sensor

I deal for those running a std lambda sensor and finding problems with ther lambda sensor not being up to the job, wide band sensor is more accurate and more capable of the job for correct monitoring of air/fuel mixture.

Sell for £110 which is around the same as the inferior standard version!

buyer to collect or pay/arrange collection

still have it?

is it a wideband or a bosch lsm11?

you cant just plug in a wide band. true wideband sensors are five wired, and cannot be read by the lambda link or the standard ecu except for the upstream sensor on the my01.

especially at the price you are talking, i presume it is an lsm11, which is not a wideband sensor.

what it is, is a narrow band sensor with some degree of temperature compensation, which makes its reding more efficient over a large range of temperatures.

Adam it is the bosch 5 wire

if it is the wideband 5 wire then you cant just plug it in to the standard ecu for closed loop lambda control on the old style car.

Otherwise everyone would be using them, in their lambda links too.

It is much more complex than that. sorry

:-)

so Adam are you saying it can only be used with a link ecu?

cause that's what it came off

so to put this in context, best suited for those with mappable ecu.

No link/motec/gems/power fc users wanting a better performing/replacement lambda sensor?

In fact am surprised Adam m doesnt need one

Adam M

actually it cant be used with any link ecu I know of.

The bosch lsu 4.7 is a true wideband lambda sensor can be used with the motec m800, but only if the wideband option has been enabled on the unit.

The pectel t6 (which I run) uses the ntk uego sensor and is currently incompatible with the bosch sensors.

Look carfully at the picture, I can see LSM11 written on the unit.

The LSM11 will give a narrowband style feed to the ecu, thus making it compatible with pretty much any ecu with narrow band lambda control.

From what I recall, the LSM11 has 4 wires. A true wideband sensor would need 5 wires and an interface driver circuit inline/in the ecu in order to function.

Another question worth asking would be has the sensor been used, and for how long. All lambda sensors have a finite useful life, and turbocharged cars produce higher exhaust gas temperatures, thus reducing the units life considerably over (well mapped) normally aspirated cars. IIRC, the LSM 11 is more rugged than the standard kit, so this may not be such a problem, but is probably worth considering, especially when it's being priced that high.

LSM 11 is 4 wire, not 5. Just confirmed this with a chap who actually has one and knows.

Adam, how many more times, it came off a linked car and was working fine

ask Pat.

Part of this confusion is my making. The lambda sensor is with the car which is in a garage, so the pic i used was the result of a search on the net for wideband lambda sensor. It is actually a 5 wire though and did come off a linked car. Was also only on the car for a short period of time (will check on the invoice date later)

pete, how many more times.

it is not a true wideband lambda sensor and should not be sold as one.

It is a four wire sensor, not a five wire. It gives a narrow band signla for use with normal lambda links, and normal ecus designed to run narrow band.

It does have some degree of temperature compensation but not much.

a true wideband sensor for a pectel or m800 is in the region of £350 plus vat, ask pat! ask mark aigin, ask me!

Regardless of that, your price for an lsm11 unused is a decent one.

and I know this, because I have one plugged into my lambda link!
