If you want to map it, buy a wideband kit and put it in the location of the stock lambda. Nearly all wideband controllers have a narrowband output so you can wire this into the original lambda cabling and issue solved. ECU stays happy yet you have a proper sensor so you can map safely.
A narrowband just changes voltage when its above 14.7 and changes again when below. Like Ruan says, you could work this out if you were mapping to 14.7 but you're not. You'll be going down into the 12s at points and theres no reason on very light throttle why you can't save some fuel and go into the 15s.
