    Can someone please tell me how to activate eco roll+ ?? My display just says simpley 'E' and whenever I'm driving downhill I tried flicking the stick up and down (middle to top and middle) doesnt do anything!! Please help really appreciated.

    It has to be enabled in the parameters. I have a Lone Mountain truck and for whatever reason, neither the performance mode or Eco-roll was turned on. After getting Premium Tech Tool and a new laptop, I spent some quality time with my ECM setting a bunch of parameters.

    Once Eco-roll is turned on, you set your engine brake to Automatic, set the cruise and don't forget to set the engine brake about 10 mph higher than the cruise is set. (Button on the end of the engine brake stalk).

    Now on any little downhill, the transmission will kick into neutral and the engine goes to idle. It automatically shifts back into gear and continues on when the speed reaches 1 mph below set point. (also adjustable in parameters)

    Eco-roll can be enabled when you're on the pedal too, but I didn't want to do that. If the engine were to stall in neutral on a cloverleaf ramp for instance, bye-bye goes your power steering and off the edge of the ramp you go.
     
    Bono84 Thanks this.

    Some other things you might consider if you have someone set parameters:

    1. Set the transmission to only start in 1st gear. Mine was starting to get clutch shake when it would try to take off in 5th.

    2. I also limited the torque in the lower gears. It makes for a much smoother takeoff around corners.

    3. Set your clock. I can't count the number of times mine went to the dealer and the clock was still off by thirty minutes.

    Premium Tech Tool is the software needed to diagnose and/or program your truck's computer. I have about $3600 into software, cables and new laptop.

    The dealer, or anyone with PTT can set your parameters for you. Probably be about an hour labor, minimum.
     
    Bono84 Thanks this.

    Screen captured this! Thank you so much sir. Can I ask you few more questions since I'm such a newbie at this,

    1. How often to do egr/dpf cleaning required? Do I wait until the warning sign pops up and do it then? Is there a way for me to check it myself? Mine is 2016 with 360k and no idea whether the previous owner has done them or not. Nor the dealers do.
    2. What kind of mpg do you get? I'm si used to during 2017 670 when I was a company driver, but seems like that truck was doing so much better I terms of mpg hauling all kinds of crap and was getting 8.0~8.5 doing 35000~44000 lbs.(60mph top) however I'm going into my 3rd week with this truck usually the light loads between 6000~20000 lbs, and im getting like 7.5 at 62mpg. Any ideas?
    3. Lastly, any recommendations on apu? My truck from lonemountain never came with neither inverter, no bunk heater, nothing. Volvo suggested me to go with the thermo king the one that covers ac, heater, and inverter all together but it is costing 12k.. since so many people saying it's unacceptable for idling with def truck.
    I would be super appreciated!!!
