So, I have had the problem of my 2 wideband readings being off. Since I used Crimp connectors when I installed, I when through and soldered/heat shrunk all of the connections.

Didn't help. Still .3-.5 off



After the first.



Wallye giving me a hand. He was quite curious about the soldering iron.





Soldered all my grounds to this new connector.





Still have crimps for the 12v power supply. I didn't have the right size heat shrink to do it, plus it's I'm not too concerned with it.




If you look closely, in this pic you can see that I was still .5 off on my test drive. Darnflabittynaggit.



Had to take a pic on the test drive!
