2019 1320 ScatPack PBM
So, I installed Hooker longtube headers, a DiabloSport Trinity tuner with an unlocked ECM and now cant get Line Lock to function. I select "Super Drag Pack", select "Line Lock" put pressure on brake pedal and hold OK button...but system doesnt acknowledge any pressure on brake pedal. Does anyone have any knowledge of how to cure this? Thanks!
