RE: Help me AEU86, you're my only hope
The reason a NB sensor hovers around a given voltage is because it is feeding its value back to the ecu, the ecu then changes the fueling to keep the given voltage hovering around a given value. When a NB sensor is used just to monitor it is capable of showing rich / lean values in excess of what is required to run a normally aspirated engine. Here is a video proving such: https://m.youtube.com/watch?v=o6y0OgSnbhk The DTM unit is monitoring using a generic NB sensor. The Innovate LM2 uses a wideband sensor.
lf the problem appears to be that the engine is running lean and that conclusion comes from an instrument reading then surely that instrument reading needs to be correct?
