aem wideband 4110 convert to lambda

can someone help me convert my aem uego 4110 to read lambda in the scanner. Right now i have it set to read afr. I had to double the stoich method for my E40 ecu because i am running 72lb injectors. I have been trying to figure it out for days with no luck. Thanks guys

Can you right click the channel to change the units?

I tried that last night but its a no go. I cant change it. Only thing it allows me to do is change decimal points.

anyone?
