    My company truck, a 2017 KW T680 goes into "Eco" mode while I'm in cruise control. If I'm set in cruise at say 62mph, it will slow me down to 53mph to save fuel. Even On a straight flat road with nobody in front of me. Anyone know how to disable or bypass this feature? Again, it's a company vehicle so I can't do anything crazy. Thanks in advance

    Needs to go to paccar and get setting changed . Mine came that way from the factory but I pull heavy so put the hard cruise setting in ecm . I find it far better on fuel that Eco deal only works if you pull light otherwise you lose so much speed the cruise needs to go to full boost to regain speed.. also it's extremely annoying following a truck set that way

    thanks for the response Magoo! Shortly after i posted this question I was assigned a different '17 T680 and that one did not have a functioning Eco mode at all, it was great but then My qualcomm went down, the blackbox for it was replaced and wha-la.... Eco mode is back with a vengeance. And my apologies for the long hiatus.
