I recently found out that you can calibrate a AEM UGEO wideband, is this true? how do you do it? Is the fact that I have it closer to the turbo than is recomended going to affect the readings?
Also would like to know how to hook it up to my datalogger. I am running MMCD 1.8

thanks in advance.

The only reason they suggest 36" or more is so the heat won't make the sensor go bad prematurely. It won't affect the reading at all.

You calibrate the aem wideband by turning an adjustment on the back of the guage. You will see a hole in the back with a thing inside it that you turn with a flat head screw driver. You have to turn this with the ignition on or car running. The guage will ight up with p0,p1,p2,p3,or p4. You will want p0 if you want air/fuel displayed. If you want lambda displayed you will want p1.

If you need the instructions, the aem forums should have them.
