Hi guys, I have been trying to hook my WB up for a week now, and could use some help. My lm7 doesnt have a CAN Bus, and the AEM WB I ordered, requires it. I have heard that I can tap into my egr pin, on the pcm( since my vehicle doesnt have egr). Trying to find out what exact pin number it is. It's on an 05 avalanche 5.3 4x4, p59 pcm
Pin 55 on the blue connector would be what the EGR pintle position 5v reference circuit is.
Try that and then enable the EGR in the calibration.
On my P59, I used pin 55 for the white wire and hooked the brown wire up to pin 41. Make sure to enable EGR on your tune and log EGR Sensor in VCM Scanner.
Check the post I just made in this forums about analog logging with this sensor.
