A lot of misinformation here. The intent for most owners is installing the wide band as a device purely for the purpose of setting the stock FV within the appropriate operating range. Not to outright control the system within the operating range. The frequency valves dwell can hang within a wide range and that entire range is not 14.7 stoich. Or anywhere close for that matter. 20-80 is not the range you want to shoot for. 29-38 is. If you are swinging that far back and forth other problems are present ranging from 02 sensor age to grounding problems with the ecu.
I will start posting all of this information directly with our products for owners to refer to as this forum, others like it and social media successfully misinform owners on how to install and utilize our product offerings to the fullest.
