Analog Wideband afr error table

[JReese]

I have a 30-0300 aem wideband to analog on pro link. Transformed voltage to afr. It matched my gauge at first and now it?s showing 7s on vcm scanner.
Removed channel and then add it again without the transformation, voltage reading is .15 at 14.6 on the gauge

Since I can’t delete, figured I’d put an update.
Even though the gauge reads properly it’s hit and miss if it will transmit the proper voltage to the pro link, sometimes it works fine. Probing the back of gauge shows it’s not wiring related, aem recommended a replacement gauge.
Aem customer service was great, I was a bit surprised they couldn’t sell me a gauge by itself or even offer a discount for the kit, but it’s out of the warranty period so I can’t be upset.
