Ive been searching around for a good wideband, and stumbled across this series of videos that really explain the wideband, how it works, and what the hell to do with it... Thought it might be helpful:

It also shows the unit in action on show "Two Guys Garage"

 

I like mine, I've used it on 3 cars so far and it's worked flawlessly.

My only gripe is that it's kind of messy, most of the time I have harness going everywhere but I've since wireloomed everything, and now it's ok. It's meant to be a permenant install anyways, so I can't really complain.

 

im planning on sharing it witha a buddy, so we can both tune our cars. Will it be diffucult to switch back and forth between cars?

 

Nope, just keep it in mind when you're wiring it up.

 

okie doke. thanks.

 

those vids are definatly informitive!! thanks for the link.
