Dual lambda sensors on Thunder


Recommended Posts

Did a LS6 engine on Thunder with two lambda sensors, latest firmware, but I can't seem to find any way to enable closed loop using the second lambda sensor. Can't find any option anywhere to tell it which cylinders belong to the second sensor and so on.

Set to wideband stoich mode.  It will still target whatever lambda you require, just it is a slightly simplified strategy compared to auto mode.  

Are there any negative effects by using this simplified strategy? Does the stoich mode fluctuates if lambda is around 1 like an OEM narrowband does, because of emissions?
