really though you're not gaining useful information staring at a gauge at WOT. you need to log and review later, data needs to be sifted and sorted. i wouldn't suggest anyone run without one, but they're not strictly necessary will a properly setup map.
the point is with ecutek you can just make the car smart enough to know what to do when something happens, rather than staring at a gauge hoping you'll react in time. you should have both lines of defense.
EDIT: to be clear i mean the gauge... not the sensor. the ecu can react to an off reading on the wideband much quicker than you can, and it can do it automatically with proper setup. no one should drive an FI car without a wired-in, proper wideband sensor.
