AEM Wideband Formula in Air Fuel Ratio = (v*2)+10

AEM Wideband Formula in Lambda = (v*0.078557)+0.751

If you have any ground offsets, add or subtract them from the voltage (v). For example, for a .125 voltage offset, ((v-.125)*2)+10. Your gauge should match the reading on the tuner/livelink exactly.
