Hi Rob, I am about to buy my new lambda sensor. I was looking at the website www.lambdasensor.com and the prices seem OK, however I am not sure what sensor I need. There is a bewildering array of different ones with different numbers of wires and different chemical content. The SBD site says you can use the sensor from the astra/cav/cally but different sensors are listed on the just lamba site for different engines and sometimes even for the same engine! What do you think. I don't want to pay megabucks, but I want a reliable sensor that will work with MBE and not upset anything, as the car is running well at the moment.
1. ignore the website and ask about the bosch OE astra etc part (i think Cemesis said it was just the other side of £50)
2. ask them for the £129 LSM11 Bosch motorsport sensor (0 258 104 002) and tell Graham he gave us that quote a while back (includes vat & postage)
the lsm11 is far more accurate around 12.5:1 - perfect power air/fuel ratio voltages (0.82 ish) and so you can use it to map full throttle.
i would have got one long ago if i had any sort of income
Cheers Rob, I think I will wait another couple of weeks and save up for the motorsport one as you suggest. After spending all that money on TBs I should really get the proper part and do the job right.
yeah, you would have thought i would have done the same over a year ago lmao
good thing with the lsm11 is that its almost a wideband sensor (ie accurate) but still uses 0-1v so no map changes are needed (luckily cos i cant figure the fecker out as NTK wont send me any technical data )
