Converting AEM wideband 0-5 volts to A/F

This has probably already been addressed somewhere but, how do you get your A/F ratio to show up on livelink (instead of voltage) from an AEM wideband?

Just double-click on the item on the left in Livelink, and it will bring up a window where you can type in an equation. I know for the Innovative LC-1 the typical equation is "v*3.008+7.35". So, just find out what the equation would be to scale the volts to A/F and type it in.

Actually, it's easier than that because the AEM wideband equation is already configured within the SCT handheld device.
Before logging, on the scanner, it's:
Data logging
Set up
Config analog inputs Y/N
Channel 1 or 2
Wideband
Select AEM from the list
Continue on with datalogging

For AEM widebands, AFR = (V * 2) + 10 where V is the analog output voltage

Try AEM wideband to xcal3 question

Use the white wire from the gauge. Ignore the blue wire.
