Has anyone ever had their sensor like... Delivered to you defective???
Started to really get frustrated, no matter what I did the AFR would NEVER stay steady under any condition. Idle, cruise, WOT, etc.. Just bounced around like a freaking Pinball. It claimed no matter how much fuel I pulled, the car would Idle at 7:1... Somehow, I highly doubt that was the case.
Tried three times recalibrating the heater and free air, made no difference. Checked all my configs like a million times, no difference.
Just happened to have another Bosch WB sensor laying around from another project, ran calibration, installed.. VIOLA!! Now the car is running a LOT better, and shows idle at 14:1, WOT it actually dips down to 12 and 11:1 like I've been telling it ever so sweetly to do.

That couldn't be a problem, Right? 7:1 or 20:1?
Gotta find out if this sensor has a warranty... Never worked right from day 1!

How long have you had it? Call support and speak to Felipe, explain the situation, and see if they'll give you another one. Innovate was good to me in the past.
Also, check the wiring. The most common thing we see is people not wiring these right and then they don't like to work right. They like a nice and clean power source and make sure it has GOOD grounds and is grounded back to where ever the MS is grounded to.

Thats a log after doing NOTHING other than changing out with a brand new sensor, running calibration on it, installing in the car and driving. I've checked all the connections which are good, settings correct, it had to be a bad sensor from the start.
Except on the first screen shot it shows O2 and the most recent shows AFR(WBO2)
