I am trying to use my AEM (30-4100) wideband with my scanner and for some reason it only shows 12.7 AFR on my scanner no matter what my gauge says or during driving. I have tried it with just the white wire to input 1 and with/without a ground from the same post as the wideband to I/O space 5. I have searched but not found an answer just people that have had it and "fixed" it without explanation. Please any help or ideas would be great.
