Can anyone recommend a place to buy Lambda sensors from, either web or around Yorkshire, pref the southern region.
Cheers
Most motor factors do them

ahhh!!! next question, which car should i get one off.
Either BuyPartsBy
http://www.buypartsby.co.uk/lambda_sensors.php --- good price very quick delivery
or for a much wider range Gendan http://www.gendan.co.uk/category_112.html

Although, rather than buying a narrowband one, get a wideband then at least its actually of use on a highly tuned engine.
Innovate LC-1 out of the box comes with its first output simulating a narrowband.

People seem to recommend getting them from one of the Megasquirt suppliers on here. Bill Shurvington (sp?) possibly.

have just been reading the MS lit and looking at the adv of the wideband sensor, I have a 3.9 RV8 which has had some mild head work and FR cam. Are
there extra cost issues with wide band sensors and if so is it worth going for the WB sensor with this engine.
cheers
Any engine which isn't running exactly as it was designed to be run, with its stock management, with new filters, proper fuel feed etc etc etc
could be running rich/lean.
With a wideband you can either run a proper gauge (XD-1) or connect it to a PC and "monitor" using the software. Much more accurate than a
narrowband sensor and will allow you to setup your engine much better and safer.
Worth doing a search of the Yahoo megasquirt_uk group on this subject

I got three narrow band 4 wire sensors from the scrapyard for a tenner, they are 4 wire ones and I took them from rover 400s and a fiesta, also got
the loom with the connector plug.They all seem to work and I have managed to get my car running reasonably using them to datalog with, the wide
throtle settings still need to be set up by feel and plug readings or with a wide band however.

Rover used a non-standard sensor on the 200/400/25/45 range -- it is a Zirconnia type like 95% of the other sensor out in the scrapyards however it
has a slightly different output voltage characteristic, this shouldn't be a problem in this scenario but has caused a lot of head scratching
when unversal sensors were fitted as replacement parts to Rovers. The Rover MEMS system won't work with any other sensor but the original spec
unit.
The reaction time of Lambda sensors slows down with age -- it is quite easy to test Lambda sensors off car using a gas blow lamp --- move the
different parts of the flame over the lambda sensor and it should give an output voltage that responds quickly to the changes in oxygen level.
while were on the subject, with the MS v3 and MSII can you add two lambda sensors or is it still only 1
cheers
The ones I got are Bosch LSH6 units, I have set the switch voltage to .45 volts, when I tested them with a blowlamp they changed rapidly from 0 to .8v
dependent on flame position.
What is the difference in the voltage spec for the MEMS sytem?
