I am not using my o2 sensor anymore as I have a PFC, can I put my wideband o2 sensor (with Innovate LC1 controller) in the stock sensor location? Or is the optimum location on the DP?

 

I have my WBO2 sensor in the location where the original O2 sensor was. Using the analog-1 output from the LC1 to supply the ecu with narrowband signal as well. I asked about this in another thread and the general consensus was that it wasn't an issue. I took the car on the track the other week and there was no overheat warning or anything like that from the LC1 so I think it's fine.

 

Did another search and read that the heat will dramatically reduce the sensors life and cause overheat errors with the LM1/LC1.

How long have you been using it on the stock position?

Thanks

 

Mine's been on there for about a month. I did run it on the track though and didn't have any overheat errors - I would have imagined if it was going to throw an overheat condition it'd have happened during on of the runs. I have a LC1 with a XD1 display.

I have a downpipe, the bung for the O2 sensor is about 18" down from the turbos.

 

If you're concerned about the heat, innovate has a heat sink available for just that reason:

It's good they mention actual temps - I'm going to see about temporarily replacing the o2 sensor with an egt probe in the next couple of days just to see exactly how hot the temps are there. That should answer the question pretty neatly.

Anyone want to speculate (or actually know) what the egt's might be around about 18" down the downpipe?

 

I doubt you'll find an EGT to fit the O2 bung, they usually use a completely different thread size. Besides, there's no need, it's well documented that rotaries run extremely hot (EGT's constantly over 1300deg, and often approaching 17-1900deg). I have an EGT probe mounted about 18" from the turbos, and can verify those numbers. That's why innovate specifically recommends the heat sink for rotary engines.

 

I bought an adapter that screwed into the O2 bung...if needed I'll try to find the website
