well some clown on here is saying that you put it like 18" inches. says teh wideband cant handle teh heat, but yet my innovate motorsports wideband uses the same exact o2 sensor on my OEM VW car, and you know what? its on teh manifold, so lets hear it, where does everyone put it....in the case of NA to turbo cars (like me), a few inches out teh DP, or like 18"?

 

to clarifty, my car out teh VW lot and OEM manifold uses the wideband in teh manifold, now its about 3"outteh DP

 

My FJO manual says 18" from the valves or after the turbo.

 

It should be at least 8" away from the turbine. You want the unit to heat the sensor to the correct temperature independently of its atmosphere.

 

i put mine near where the stock O2 is, right after the oil pan.

What do you beleive is the best way to mount the o2 sensor for portablity(tuning lots of cars). You cant just stick it in the muffler, so what are other people doing to tune cars that dont have an extra o2 bung?

With the FJO you can splice in a honda 02 connector, so the narrowband output can be sent back to the ecu.

 

Reading about the LM-1 on some of the other discussion boards, the engineer that designed them said to put them as far away from the turbo as possible...that Bosch unit won't give proper readings if it is too hot.

Hi Y'all,

Thank's all the people on this thread for all the interrest in the LM-1.

Before all of you in the group buy will ask, the most asked question (which has not made it onto our web-site yet) is:

Where should I mount the sensor?

Answer:

Depends on your application.

The coolest spot is the best. Experience so far has shown that right before the cat is typically the coolest. The sensor should be mounted at a 9-10 o'clock or 2-3 o'clock position. The Bosch wideband is sensitive to its housing temperature. Specially Turbo applications with wide pipes retain a lot of heat in the exhaust system. This is because wide pipes have a high volume to surface ratio which slows down the cooling of the exhaust gases by the pipe surface. The same is true for coated exhaust systems. This makes the sensor housing hotter through heat conduction by the bung. By mounting the sensor at an angle under the car allows the under-car airstream to cool the sensor housing. Of course for those with extremely hot exhaust systems (like blown or turbo'ed rotaries) a possible remedy is an exhaust bypass pipe of 3/4" or 1" diameter in which the sensor is mounted.

Regards,
Klaus
