Display for Factory (06+) Wideband?
Are there any displays that are compatible with the OEM Wideband for MY06+ models?
Based on this ECU pinout for the primary 02 sensor, it looks like the AFR signal is differential...as opposed to a single 0-5V analog as with most Widebands:

I believe PLX devices can display the oem wideband because it connects to your ecu through obd2 port. I wouldn't run off of the oem "wideband". I personally saw a marginal difference between my bosch wideband and the oem "wideband". Oem read 12.5/1 @ WOT yet actually was close to 14/1 afr.
The PLX gauge actually reads and displays most sensors off the ecu. When PLX reads the sensors off the ecu it tends to display them in 4 rows. It won't let you single one out to take up the whole display unless you have one of theirs hooked up individually. Kinda limited when it reads off the ECU., but still reads nonetheless.

Interesting on the accuracy of the wideband though...I read somewhere else on here that it was accurate within .1 or .2

The oem s2 sensor is very close match in afr between aem wideband and my oem wideband. Never had a issue! was tuned etune by evans awhile back (and he uses the stock wideband afr)then took to local dyno for pulls and afr reading did 430whp

If that was the case then its possible that my primary 02 sensor/OEM wideband was off but both(OEM and Bosch widebands) were checked and compared between the shops wideband which was put in the secondary 02 sensor bung(Tp/HFC/CAT) location when the car was getting tuned/dyno'd. The shops wideband reading was pretty much spot on with the bosch wideband I had installed. I did do some research on this and noticed I wasn't the only one that had this issue. Found out its more of a hit or miss. Some are spot on and others aren't. I'd at the least get it checked/compared before relying on it.
