Wide Band O2 Sensors

[1 BAD 03 MM]

Was wondering if the MM has wide band or regular O2 sensors.

I just read about them in an article somwhere. The regular ones read between 12:1-15:1,16:1 Air fuel ratio. The wide bands do something like 9:1-20:1. Better for computer tuning?

Thanks for the link. If these were installed, can the tune be more aggresive?
