if anyone needs bosch bits if you e mail or post a part no or description i'll see how cheap i can get it as i work for them.
this includes spark plugs(super4 less than £10),filters brake discs, bulbs(blue £4),belts etc.
i think standard discs for the front are about £40 a pair.
do it you know it makes sense
save the money for mods.

Hi Richie,

How much would you be able to get the Bosch LSU4.7 lambda sensor for if you had an order for several... 3+ at least?

can you give me the bosch part no usually 10 digits long it makes it easier my end

Moray is this a wide band sensor or narrow ? if it is wide band then I would also be interested .

This is the wide band sensor. I've just been reading the tech stuff and noticed that Bosch don't recommend extending the 1m cable - will this still do the job for the Scoob?

(No, there wasn't a part no on the tech stuff either!)

Are you saying that fitting one of these just to provide input to a lamdalink is a bit extravagant?

Richard

There is no point in fitting one of these sensors to a standard ecu... the best that could happen is no change in operation, the worst is incorrect labmda information causing ecu probelms and possibly engine damage (but I doubt the engine damege bit is overly likely as the standard ecu should sanity check the sensor input).

Moray, I doubt there would be any reading whatsoever from the lambda sensor given the way pat explained to me that they work.

I would guess you would therefore get a check engine light, unlike with the buggered lambda sensors on early cars that just ran rich automatically.

I have a feeling that these simply are not going to work with anything less than a pectel t6 which is v dissapointing, but then I havent chosen my ecu yet.

Perhaps we can persuade bob to fit and map pectels, then I might consider one!

Interested too

Justa quick note to say before everyone jumps on the wide band lambda ensor bandwagon, you have to be sure it is compatible with your ecu.

I believe pat reckons it is with the pectel, but the motec is a different story. The 4.7 is supposed to be a new breed (pat knows this stuff, I dont) which lasts around 100k miles unlike the previous 50 hour jobbies.

I am certain they dont run with the jecs, which means unless you have a motec and have done the research to say they are, they wont be much good to you.

The other option is you could be pat and run a pectel, in which case you wouldn't need me to tell you this.

If the price is right, I'd fit one as a secondary only for the lamdalink to give me accurate data.

Only problem will be getting the d/p welded and tapped for a second one.

Gents, a wide band sensor will work like any other, it also provides for pretty good output to suit the lambdalink, mapped a car recently which had the Bosch sensor in it (don't ask what it was doing there) and did some correlation work with it.

The oem ecu software is written specifically to use the oem narrow band sensor though and will not function in the same way using the wide band.

For the wide band to be useful and meaning full you need to work out what its output gives for a range of afr values, then you can adjust the lambdlink callibration to suit. It should only be used with aftermarket ecu's though.

The lambdalinkj is designed to use an oem sensor and, as such, specifically focuses on the lower afr area which is used for power mapping, a wide band would not provide for that much advantage under those circumstances.

(think the MY01 uses a wideband as its front sensor though and a narrow band at the rear position)
