Well, I've only got about 100 miles on mine so far, but it seems to be do fine. I have another issue right now that I'm chasing down that's unrelated.
Nice thing about the PLX is the ease of hook up. One wideband wire, one narrowband wire (if you need it for anything, most don't), and one ground wire, plus two more wire to the controller, for power and ground.
The WBO2 sensor cable is about 8' long and is plug and play.
HOWEVER, they send you an out put connector (output from the controller to your equipment), some wire, a few connectors and a couple capacitors. It's up to you to wire that all up. Not a terribly difficult task, but here's the rub.
They also include a couple of "noise suppresion" capacitors that need to be hooked across the analog output wires and ground, feeding your "device" (ecm or powerlogger).
I don't know why they couldn't have designed those into the controller, :frown: Kinda tough getting three wires and two caps all wired together without shorting anything together. They're really really small and fragile.
But other than that stupid anoyance, all seems to be working well.
