No they can't, only some standalones can like Motec, AEM, Speedpro.peter96 said:Can the ecu software use the wider more exact A/F values of a UEGO sensor or would they just be converted to a rich/lean value?
Is there a section of code that can be remapped?
You can run in closed loop through the entire operating range of the motor by just filling the VE table of the map with the desired A/F ratio. There is some risk if you have sensor failure though or an exhaust leak of some sort.James said:Is there a particular advantage that you see in using an UEGO sensor? I'm just curious what your train of thought is.
No because a regular O2 sensor is only accurate within a few percent of 14.7:1. This is only for cruze and low load type conditions refered to as closed loop operation.James said:Oh. Can't you do that anyways with the stand alone system by itself? Most stand alones don't include new UEGO sensors do they?
