I still don't understand why us manual fans can't get high idle function with our 6 speeds . I drove Cummins powered concrete trucks for years and all of the electronic engines used the cruise control to idle them up just like DC is doing and those all had Roadranger manual trans . I would almost guarantee that function is already in the Cummins ECM as I find it highly unlikely they would have a different ECM for that application . Just waiting for one of the many sharp tuners out there to " crack " the code I sure would like to use the one touch method instead of the calibrated stick method I use now !!
