For 117CI Touring from 2024 and 121CI VVT Touring from 2023 (cruise control and riding mode selector functions remain active)

• The ThunderMax EFI system with AutoTune is built to deliver uncompromising performance.
  
• It works on any motorcycle, whether it's an unmodified bike, one with a performance exhaust, and/or a performance air filter, or any other performance modification installed.
  
• The AutoTune self-tuning function of the ThunderMax will continuously tune any fuel-injected Harley engine for maximum performance.
  
• It is a closed-loop wide-band system which means it continuously automatically adjusts the air/fuel ratios every time you ride, regardless of changes to the motorcycle or any environmental conditions such as temperature, barometric pressure, humidity, or a change in fuel quality.
  
• Once installed, the ThunderMax with AutoTune automatically fine-tunes the base map to your riding conditions and habits every time you ride.
  
• With the ThunderMax, you will experience easier starting, a smoother engine, crisper and improved throttle response, and increased performance at all riding levels without sacrificing fuel economy.
  
• You will also eliminate exhaust popping, spitting, and/or backfiring for a better sound.
  
• The ThunderMax is an industry award-winning product that outperforms all other tuning systems in all riding and performance categories and comes with a 3-year limited warranty.
  
• Note: ThunderMax installation requires an exhaust with 18mm exhaust sensor bungs as used on 2007-2009 models or modification of the original exhausts to accept 18mm O2 sensors.
