Yup
After tuning mine with a wideband, that's what I'll be fitting. 4 wire version...

If you believe you're not crazy, whilst everybody is telling you, you are - then they are definitely wrong!

a wideband lamba sensor aids mapping the engine, as it can tell how rich and lean the mixture is, whereas a narrowband can only sense if it lean or
rich but not by how much.
however megasquirt at present doesn't support a wideband sensor so u can't use it wired in to ur megasquirt.
the different number of wires for the lamba depends on wether it has a heater wired in. for a lamba to work properly it needs to be hot, this will
happen with the exhaust gases, but the heater gets it up to temp within 30 secs or so.
the other wire that can appear is generally an earth. as some earth thro the casing and some have an extra wire for this.
this info can be found on the megasquirt website

oops my bad, i haven't been on the website in a while. i assumed that was the reason for the previous post saying they were going to use a
narowband sensor after setting it up on a wideband sensor.
