I need some help here guys I have an AEM UEGO wideband sensor and I cant figure out how to wire it to my ECU, its got 3 cables, Brown differenciated grd, white 0-1v narrowband signal and a 0-5v signal.

for some reason my wideband gauge only reads the 0-1v and it goes up and down when I use the launch control and revs it goes rich, and I tried on all 4 wires that go to the ECU and since the o2 sensor has been removed my car was idleing at 1200rpm kinda... and no changes at all in the idleing...


Yes the UEGO has power and is grounded directly to the battery...

if you have the same controller as me

red: b+ in diag box
black: e in diag box
white: hook to the stock primary O2 sensor wire

set your controller to P4 using the flat screw set in the back and watch the read out (changes P1, P2, P3, P4)
