Wideband O2 sensor in stock position

[soldave]

One of the features of the new version of ECMLink that might be implemented is narrowband simulation. The idea is that you use your wideband O2 sensor in the stock O2 housing location in place of the normal O2 sensor and that controls everything as well as logging your AFRs. However, am a little concerned about placing the O2 sensor from my AEM Uego wideband that close to the turbo when I'm running EGTs measured at a peak of 1550F just before the turbo.

Wonder if anyone has had experience with a wideband sensor there, and especially if you've had a sensor fail on you that you could definitely attribute to heat degradation of the sensor. I know people will come in saying it will shorten the life of the O2 sensor but am wondering if anyone has actually tried this and got any real world results. The guy in charge of ECM Tuning has this setup and runs hard road courses with no problems as of yet. He also uses a small copper plate that the O2 sensor goes through to act as a heat sink and to channel air onto it.

I thought Thomas had his mounted downstream and used the delay function in the Narrowband sim to compensate for it?
I'm going to leave mine in the front pipe just forward of the firewall and use his instructions to delay the signal to the narrowband.
Hope that made sense?
I do believe there are quite a few guys in the states running it in the stock location with no problems.
Has Thomas sent you your forum login details yet? One of the guys on the ecmtuning forum should have an answer for this one too

Think about it for a minute, how different is the A/F sensor to the O2 sensor? Not much. Why would it have a problem? It is afterall designed to be fitted in the exhaust so it can handle heat I reckon you will find it has been designed and tested to cope with what ever you can give it.

That's my general thought as well. I have mine located in the stock front O2 location now and haven't had any problems at all. I originally had it in my rear O2 location, but that was because I still had a factory front O2 sensor at the time.
