HELPPP>>>> while using cruise control afr goes from 16 to 13 with no reason....
while on flat ground with cruise control set at 65mph the afr goes from commanded 16 to commanded 13. there is a very quick drop in timing instantly before the afr is commanded to 13 then timing goes right back to where it was but yet the afr does not change unless i made a big change in throttle or speed. abuse management some how getting activated ???
]NOTE frame 800-810 is the concern.
attached is the tune file in the truck and the data log from that tune file.
