It depends on which input slot on the flashcan you have wired up the wideband.
Put the red wire in the "E" slot to make analog 1 in the wideband read as EXT.AD1 in the scan tool. Analog 2 (white wire) goes in "C" The earth in"D".
Program analog 1 to the lc-1 settings. Analog 2 to a flat 2.5 volts & change the generic txt expression for the LM-1 to (({EXT.AD1}-({EXT.AD2}-2.5)*3)+7.35 .
Then you are good to go.
