Wideband lambda sensors

I know that the Subaru Legacy and Outback uses the Bosch wideband sensors. Most of the VW use them like the Golf GTI and most of the 1.8T powered ones.

 

Any idea if the lambda sensor can be bought from local stockists?

Yes. At least i know the VW one can be bought of Xinzhong (62916051), not sure if it's Bosch, but no harm calling to ask.

If it is VW and is used on the models listed, confirm it is the Bosch LSU 4.2 one. Looking at the Bosch part number ending with 7200 or 7057/58.

 

Got to do some wire splicing too. The connectors are different.

Is it for your CNG project? The ECU must be able to read wideband right, since the voltage will be of a different range and sensitivity than narrowband.

Yes for the CNG. The standard ones we have cannot read 17:1 AFR. I believe the CNG ECU can do that. Or.....I can hook up Megasquirt to replace the CNG ECU. idea.gif
