Wideband Control for Link G4+

[Cormac]

I'm currently looking into getting a wideband installed in my R32 skyline with Link G4+ ECU. I'm trying to figure out what I need before discussing with my tuner. 

Does the Link G4+ have onboard control for a wideband sensor, or will I need to order a CAN-Lambda Controller as well?

I'm finding conflicting information on this, but is it also possible to wire a lambda into the ECU without any controller? Will this be an analog input instead of digital? Can there be issues with this?

The Link G4+ Fury and Thunder have internal wideband controllers, all other G4+ ECUs require an external wideband controller and this includes R32 plugins.
