If you wire them right, they'll work right. Mine has been flawless for 2 years, except I had to buy a new O2 sensor from running race fuel.

 

Wiring is all right so easy there buddy. I called the place i bought and said that if my wiring is fine then call Innovate and if they dont replace it then he will.

Im not getting any power at all even the led isnt flashing. He told me it will lose all power if the sensor is junk.

 

I just put one of these in this week with the DB gauge. My led didn't work at all, but I know it has power because I felt the sensor heat up during calibration and my gauge is displaying information.

It is reading really rich though and I know the tune is good because I saw the AF on the dyno about a month ago and I haven't changed anything. I'm waiting for a serial to usb adapter so I can hook it up and play with the programs that came with it before I do anything else.
