Add Wideband Channel in VCM Scanner

Open the VCM Scanner application

Click the "Add Channel" button (gear with the green +)

In the channel selector, scroll down to the External Inputs section. Click the small "+" next to "MPVI2, MPVI2+, MPVI3"

Click the small "+" next to "Pro Link, Pro Link+"

Double-click "MPVI2 PL A/D Input 1 (Red)"

Click "Close" on the Channel Selector window

Find the newly added channel in the channel list, then right click on it

Click "Transform"

In the "Transform Selector" window, click the small "+" next to "Equivalence Ratio"

DO NOT select the Air-Fuel ratio option. All of the custom math and tuning parameters on our end work with Equivalence Ratio.

Double-click "AEM 30-(03x0,2340,5130)"

Verify that the transform was successfully applied to the channel. It should look like this.

Your AEM wideband (30-0300) data is now ready to be recorded with the rest of the vehicle data.
