Oxygen sensor
Is it possible to replace the original sensor, Bosch 0 258 003 011 I think, with a Bosch LSU 4.2 and a Innovate LC-1 kit simulating the original narrow band sensor.
I can not find dimensions of the original sensor.
Has anyone tried this?

Hi Rdhayward!
13942 is not a wide band sensor?
When I searched for information I read this about soldering the sensor wires.

It is precisely the same sensor as OEM. The price difference is due to the proprietary connector.
And whoever wrote that ad is repeating a fairy tale, probably originated by some gnome ignorant of the difference between volts and ohms. I've been tinkering with engines since lambda sensors were newfangled thingamabobs used in loop with "feedback" carburetors. Soldering works pefectly well; heat-shrink tubing is a nice finishing touch.

This datasheet from Bosch is a little confusing.
See section "Application hint" ... "Install at a point where the gas is as hot as possible" ... "Observe the maximum permissible temperature".
odb812, are you sure?

A wideband outputs in the range of 0-5 volts. I forget what the range for motronic is, but it doesn't line up.
Sensors have been known to fail when installed too soon in the exhaust, but 968s are a bit cleaner than cars I've seen this happen in.
RDHayward's method is accepted by most but there is a little controversy. O2 sensors need fresh air which they draw from between the wires going into the sensor. You can solder and heat shrink them as long as there is no solder or heat shrink within a couple inches of the sensor. This is why the insulation over the wires stops a few inches short of the sensor on the factory sensors.

I think I understand now.
I have talked to a dealer, and it is the part of the sensor inside the exhaust pipe that should be "where the gas is as hot as possible".
The outer part of the sensor is sensitive to heat.
Simulating the narrow band sensor with one analogue output, and displaying the other one should not be a problem. (?)
So the question is: is the original sensor position cool enough for the new Bosch LSU 4.2 sensor?
