I have an AEM 30-0300 wideband and a P59. Last year it connected it to to Pin 55 on the blue connector and had everything working perfectly. I even wrote a how-to. Over the winter, I changed to the 2 bar OS mod and after that, the wideband logging stopped working. In the tune, it seems like my EGR settings are gone. I assume the 2 bar mods over wrote the EGR part of the P59.
Anyone else have this experience? I guess I'm going to move the AEM output over the AC pressure switch which I believe is pin 14 on the green connector. Does that sound right?
