Installed new S300 and AEM wideband exactly as directed from the place I bought from, Xenocron. WB reads correct and verified 5v coming from white wire. Voltage on display stuck at 3.8v, with AF frozen at 17.7 Yes this is D14, but have always used this pin on other setups. Never mind the nasty fuel table, this was just to get it to idle.

So there is no fluctuation in voltage on the signal wire from the wideband?

With the car at idling at 14.7, I probed d14 and it read 5v. I did not rev the car while probing.

If that is the case then you may need to contact AEM as it sounds like you might have a faulty wideband controller.

Reading owns me. Had to ground brown wire.
