More about ThunderMax EFI...
Now ready for 2007 Harley-Davidson® fuel injected motorcycles!
The Thunder Max Electronic Fuel Injection (EFI) Controller is a replacement for your stock Harley-Davidson® control module. The TMax controller performs ‘Automatic’ tuning when coupled with the optional AutoTune Module (as shown).

When used as an EFI Controller replacement for NON exhaust sensor equipped, fuel injected Harley-Davidson® motorcycles, the controller performs calculations based on a set of data specifically tested for your equipment combinations.
