Is it possible that the second wideband Can be made for a fueltrim adjustment

So the first lambdasonde is used to adjust fuel like normal and then the second is used as a longterm trim lambdasonde like OE ecu does it ?

This Way fuel trim could be made perfect ,

Also is OBD2 a possibility on a later model , is comming sooner then later also for the aftermarked ecu marked , so we are able to use the ecu on roadcars

Thanks
