Message: [QUOTE="CATDiezel, post: 1116617, member: 4387"] Well. That's interesting Dustin on the lambda sensor readings. I can understand the swing below 1 for lugging situations to give more fuel in order to come out of the below 1 threshold. 1.5 is probably a setpoint of what they would consider too lean. And I know most guys will bock at too lean but in the emissions world too lean produces different emissions. I'm certain you know more about lambda than I certainly do concerning diesel, mine is focused mainly on NG and I'm not sure if the meaning is linear. I know on big bore rich and lean are Co - equal with diesel due to compression ration and volumetric efficiency of a big bore NG engine. Look forward to more of your results and testing. [/QUOTE]
