2024-2026 L5P Duramax SOTF Instructions

Use these steps to run your AMDP SOTF tune on your 2024-2026 L5P Duramax with the factory steering wheel cruise controls.

How SOTF Works:

  • Open tune selection: Hold cruise cancel for 1.5 seconds.
  • Pick your level: Use cruise plus or cruise minus to move between tunes. Tap cancel or wait 6 seconds to close the menu.
  • Smoke control (LBF): Outside tune selection, hold cruise cancel for 3 seconds to switch. Gray is standard fueling and green is LBF.
  • Rumble or Hiss: Outside tune selection, hold cruise up for 3 seconds to switch. You will see 10 or 20 flash and hear the exhaust note change.
  • Settings stay saved: Your tune, LBF and Rumble or Hiss choices stay set until you change them.
  • Hide the display: Hold cruise cancel for 5 seconds. Your tune stays locked in. Hold cancel for 1.5 seconds to show it again.
  • Cruise control note: On trucks without adaptive cruise, hide the tune display to see your cruise set speed. With adaptive cruise, the number may flash after you turn cruise off, and it resets the next time you open tune selection.
