Normal
Since I'm on this side of the board, I'm going to try to add some tech.A Wideband O2 won't be read by a stock ECM (different for an aftermarket ECU) and will be added next to a normal O2 sensor. It doesn't replace it. It will be plugged into a gauge or a datalogging system/computer.If you have an engine extremely dependent on AFR (like a high boost / nitrous application where a quick change in AFR might mean instant engine failure), it makes sense to have a gauge in the vehicle and monitoring the AFR live.In a standard NA application, I think that it is unnecessary and using one during the tuning phase should be more than enough.Now if you have an aftermarket ECU, like a Holley HP etc, you might use your wideband to tune the engine AND keep running one to adjust your fueling (done by the ECU) and monitor the engine health (done by you on a display).
