So i hooked up my wideband and i can't seem to figure out how to get it to read correctly. It keeps displaying in Voltage on the Display and I'm trying to get it to display the ratio. please if someone could help me out with this.

I have the white (digital) wire connected to the D14 O2 Pin.

now lets just say i start from scratch. where do i go from there?

I know I have to go to Options > Settings > Units tab > Lambda Unit > select Air Fuel Ratio

also under Closed Loop Advanced > Wideband input source > selected (D14 O2) i don't know what voltage offset i need to put.

under closed loop what do i put for Wideband target voltage? also do i disable O2 Heater?

also to monitor the A/F Ratio on my display what sensor do i monitor and how do i set it up to read air fuel and not voltage?


sorry if this seems confusing. I'm severely lost when it comes to setting this damn thing up properly. if someone has a how to link that could help me out that would be awesome. or if they want to help me set this up step by step it would be much appreciated.

In your "sensors" tab, scroll down to "AF". Thats your AF ratio. right click it, then "properties" then make sure the min value is 0, max is 22. Then go into the "display" tab, right click in the blank space, then click "new value". it'll pop up an rpm gauge, right click on the gauge, pick sensor, then choose "AF" to display current air/fuel
Disable you O2 heater. You shouldnt need a voltage offset, so keep that at 0.
The target voltage is what you'd want the ecu to try to adjust to in closed loop if you select "closed loop- voltage target". So you'd input what voltage correlates to the desired AFR while in closed loop (usually around 14.3-14.8 afr)
Make sure to setup your voltage/lambda conversion table according to AEM's instructions

Which Wideband do you have from AEM - They have different scaled values depending on which unit you have.
