I can't get my PLX SM-AFR wideband reading in link to match my gauge. It is usually .3 AFR higher in link. At idle the gauge hovers 14.7, so I trust it. I hooked up a buffer circuit and it didn't help, but I may have done more damage than good. I wired it up wrong and connected the PLX module12V power ground wire to the sensor side ground of the buffer circuit. The ground on the ECU side of the buffer circuit was connected to the ground bolt used to hold the ecu in place(GVR4 setup, not sure if its the same on the dsm).
I'm using the EGR pin to log the wideband.
Thanks.
