TTS MasterTune2 Single Programmer Kit for '01-21 Delphi Equipped Harley-Davidson Models

TTS MasterTune 2

If you need more refined performance from your bike, you need the TTS MasterTune 2. Your stock Harley Delphi fuel injection system may be sufficient, but is “sufficient” really good enough? This programming kit works with your MasterTune to optimize your bike’s performance to meet fuel and exhaust specifications. It’s a great way to push your bike harder than before.

Programmed Performance

The kit works with the TTS MasterTune 2, DataMaster 2, VTune 3, or Flight Recorder to ensure that your Harley Delphi fuel injection and management system is dialed in perfectly. This single-bike programmer is designed for tuning 2001 and up model Harley bikes equipped with the Delphi system.

The kit includes an interface, all necessary firmware, and the software you need to bring it all together, making it one of the most comprehensive Harley tuning kits available. Unless you already have them, you’ll need to order 6 pin or 4 pin MasterTune cables separately.
