Hi all,

I keep hearing about the importance of wiring the wideband controller ground to an engine/chasis ground. it will add more complication to my setup because I'm pulling voltage from inside the car (fusebox) and I just tapped the ground into a nearby screw on my 2007 C6 Z06.

I've also been told that I only need the signal out from the AFR 500 to go into HP tuners, and not the ground.

Any feedback is appreciated, thanks!
