Message	Sounds to me you have a ground differential between your wideband ground and your ECU ground, which is apparently made worse when you turn on heavy electrical loads. I had this issue...I ended up ditching the narrowband emulation and ran 2 sets of sensors. 2 narrow band for the ecu and two widebands...
