I ran an LC1 just downstream of the first bend on the downpipe with no issues for 3 years (I do have a heat shield on the sensor). I know the installation instructions say only one wire to one device, but my application has three devices that need the signal so that wasn't an option. My LC1 never flaked out until about 6 months ago with the issue being my fault IMO and I replaced it with an LC2. The LC2 works but I will go to the AEM or PLX next time as there are just too many people having too many issues with the innovate products.
