AEM Failsafe O2 sensor placement

[BMC]

Just trying to figure out how to get the above mentioned Failsafe component installed properly. I've got a 2013 Speed3 with a Catted Cobb downpipe. AEM wants the sensor 18" downstream from the turbo but on the upstream side of the CAT, at an 8-10 degree angle. Since the CAT is only 6" or so from the turbo that ain't happening. There's an extra bung for another sensor on the cast portion of the downpipe but that puts it pretty much directly on the turbo. Big heat! I could have another bung welded on just above the CAT but it would still only be a few inches from the turbo. I'm likely missing something but it looks like this AEM product has installation parameters that make it unusable for a Speed3. As replacement sensors aren't cheap, I'm wondering what others did when they came across this.

I've had no issues whatsoever with the sensor installed on the second bung right next to the primary wideband O2 sensor on my CPE downpipe. One thing I do notice is that the AEM AFR Failsafe reads about 0.2 points richer than the OEM wideband through the Accessport, so definitely take that into consideration when setting up what AFR the alarm triggers at.

Thanks for the response. Just had a chance to look at the video. Basically the same O2 sensor configuration on the downpipe as mine. Glad to hear you've had no issues. It was suggested that I'd be burning through sensors quite quickly, that close to the turbo. How long've you been running it like that?
