EMS Lambda sensor

Hey is there any factory o2 (lambda) sensor that is compatible with an ems dualsport that is easy to find at a wrecker.
according to their website www.enginemangement.com.au the sensor is like $400 
I know that it's an open loop system.
Apparently the lambda sensor is 4 wire (my factory one is 3 wire) I think 4 is wide band and 3 is narrow.
Does anyone know of a car i could find at a wrecker that the sensor would be compatible??

what sensor do they suggest?
4 wire is heated narrow band
3 wire is heated narrow band
2 wire is non-heated narrow band
1 wire is non-heated narrow band
Bosch LSM11 is a calibrated NARROW BAND, that is often called a wideband but it isn't really.
Bosch LSU4 and NTK L1H1 are widebands....
that pic on their site looks just like the bosch 4 wire heated sensors i got from the US for $60.

Knowing how limited the EMS units actually are compared to that of a Motec or Autronic i would not trust it to actually do the job of tunning through the o2 sensor, just put it on the dyno and tune it that way. The $400 you would spend on the sensor would easily pay for the dyno tunning anyways.

u also have to upgrade the hardware on the dualsport to run the wide band. look on the back of the unit if there is a lambda symbol near the serial number the upgrade has been done the bosch sensor recommended is the same one dyno dynamics/autronic use and is about $375 but in my opinion is not as accurate when running off the dualsport QI4 unit.

yep but the sensor's expensive!
I suppose the ecu is only as good as the tuner!
for around a hundred dollars you can get it upgraded to the latest dualsport program. (not sure what the difference is)

EMS state that you use a bosch wide band sensor, hence the price and im fairly certian that you will only find narror band sensors in production cars. (not 100% sure there might be an exception)

There are a few that use wideband, but only a few.
Sideshow: what do you think of the Bosch LSU4? I'm thinking of getting this kit in the not too distant future, and that's what it comes with.
http://www.widebandcommander.com/productinfo.htm
It can be found on eBay for about $430USD.

Any of you out there have much experience with the dual sport?
The admin on the EMS forum is basically useless. Answers most questions like so. "the manual is in the download section"
Which is great, when the answers to the questions asked can not be found in the manual in the download section 
I wouldn't mind adding any of you out there that have played around with the DS to my MSN list so i can pick your brain when i have queries.
Cheers,
Ashlin.

Look at this link. http://wbo2.com/
Aussie company.
I have the 2AO kit, WB sensor and seperate LED AFR display, was around $400 You can buy the various Bosch Wideband heated sensors through this mob at a lot less then you would expect to pay elsewhere. My WB sensor was less than $100.
AUD$300 gets you the new compact 2EO DIY AFR meter kit with sensor. About $150 more for a pre-constructed unit(they are a very complex kit to build). Best value in town IMO.
I don't even think the EMS uses a fully wideband system O2 system. It's a the old LSM-11 sensor which realy aren't true WB. The new WB sensor are so much more cheaper and much more accurate.
Good luck.

I must say, I'm kind of curious as to whether, say, the Wolf, EMS, WB02, etc. kits really do work particularly well. I've already got a Motec PLM, so if anyone who lives remotely close to me buys/has one of these other units and would be interested to compare accuracy, let me know.

if you really want to know, send an email to Bruce and Al (the MS guys) to develop their PWC (precision wideband controller), i think they went and bought many different models to work out the speed and precision with which they actualy controlled the sensor, and how accurately that reflected the actual gas content (using specific pre-mixed gas cylinders)...

Check out the order page. The 2E0 has the integrated AFR display. The 2E0 DIY kit without a sensor is around $200-$230 and a suitable 7057 sensor is $90. The prebuilt units are around $500 with a 7057 sensor.
I have the 7057 sensor connected to 2A0 version which I built.
My display is a seperate device.
I will say though to all, again, that these kits are very hard to build. They are small and very complex. If you're not right into electronics buy the pre-built unit.
Good luck
