Can someone please guide me through setting up the lean cruise on my 8.1L motorhome? You can assume I know nothing, so spoon feed me. I wanted to do the AutoVE procedure, but the pcm does not contain the proper PID's. GM.AFR for one. So my only way to get additional mileage is the lean cruise. If I cannot get this to work, this license is worthless. Thanks for any help.
