Hey guys. I cannot figure out how to properly calibrate my wideband to work through my EGR. I have tried every formula I can think of. I have a digital AEM wideband gauge, which has a range from 10 to 18 AFR. With the car off, but the ignition in the run position, it is outputting about 4.29-4.31 volts through the EGR input. Can anyone help me out?
