Review TOTAL Harley Fuel Systems Box Control Do Not Relis fits EFI 1995–2005
The **Total TF-240 Harley-Davidson Fuel Box Control (1995 2005 EFI Relis)** is a high-performance fuel system upgrade designed specifically for Harley-Davidson s Evolution Fuel-Injected (EFI) engines from the mid-'90s through the early 2000s, including models equipped with the **Relis (Reliable Electronic Ignition System)**. This meticulously engineered solution addresses the common challenges faced by riders seeking enhanced throttle response, improved fuel efficiency, and a more refined power delivery without sacrificing reliability or ease of installation. Built to complement Harley s EFI architecture, the TF-240 features a **high-flow fuel pump** with a robust 240-lb/hr capacity, ensuring consistent fuel delivery even under aggressive acceleration or sustained high-RPM conditions. Its **durable aluminum construction** and **sealed O-ring gaskets** provide a leak-proof seal, preventing fuel spills and maintaining cleanliness in the fuel box, while the **integrated fuel filter** captures contaminants, prolonging the life of your engine s delicate EFI components. The TF-240 is engineered to integrate seamlessly with Harley s stock fuel rail and injectors, offering a direct replacement for the factory fuel box while accommodating aftermarket upgrades like larger injectors or performance fuel pumps. Whether you re chasing extra torque for cruising, improving cold-start reliability, or simply ensuring a steady fuel supply for long rides, this fuel box control unit delivers a **no-compromise performance boost** without the complexity of full fuel system overhauls. Ideal for both stock and modified Harley-Davidson engines (including Twin Cam and Evolution models), the TF-240 is backed by Total s reputation for precision engineering, ensuring compatibility with Harley s EFI Relis system while providing the durability and performance riders demand.
### **Pros and Cons of buying a Total TF-240 Harley Fuel Box Control (1995 2005 EFI Relis)**
#### **Pros:**1. **Improved Fuel Efficiency** The TF-240 is designed to optimize fuel delivery, reducing unnecessary fuel consumption while maintaining power. This can lead to better mileage, especially in stop-and-go traffic or under light loads.
2. **Enhanced Engine Performance** By precisely controlling fuel injection timing and quantity, the unit can help prevent fuel wastage, reduce carbon buildup, and improve throttle response. Some riders report smoother power delivery and better low-end torque.
3. **Compatibility with Older Harley-Davidsons** The unit is specifically designed for Harley-Davidson EFI (Electronic Fuel Injection) engines from 1995 2005, including the Relis system. This makes it a straightforward aftermarket solution for those looking to upgrade or restore stock performance.
4. **Ease of Installation** Compared to full EFI rebuilds or tuner setups, the TF-240 is relatively simple to install, often requiring only basic wiring and connection to the existing fuel system. Many users find it a plug-and-play solution.
5. **Cost-Effective Upgrade** Priced lower than full performance tuners or engine modifications, the TF-240 offers a budget-friendly way to improve fuel economy and engine health without major overhauls.
6. **Reduced Carbon Buildup** By optimizing fuel delivery, the unit can help minimize carbon deposits on intake valves and pistons, potentially extending valve and engine component life.
7. **No Major Modifications Required** Unlike some aftermarket solutions that require ECU flashing or extensive wiring changes, the TF-240 integrates with the stock Relis system with minimal adjustments.
---
#### **Cons:**1. **Limited Power Gains** While it improves efficiency and throttle response, the TF-240 is not a high-performance tuner. Expect modest gains rather than significant horsepower or torque increases. Riders seeking aggressive power upgrades will need a different solution.
2. **Dependence on Stock ECU** The unit works with the existing Relis ECU, meaning its performance is constrained by the stock programming. If the ECU is outdated or faulty, the TF-240 may not perform optimally.
3. **Potential for Compatibility Issues** While designed for 1995 2005 Harleys, slight variations in wiring or fuel system layouts between models (e.g., Sportster vs. Touring) could require minor adjustments. Always verify compatibility with your specific bike.
4. **No Direct Tuning Capabilities** Unlike modern tuners, the TF-240 does not allow for advanced mapping or customization. Users cannot adjust fuel tables, ignition timing, or other parameters beyond what the unit pre-programs.
5. **Mixed User Experiences** Some riders report noticeable improvements in fuel economy and drivability, while others see minimal changes. Results can vary based on the bike s condition, riding style, and whether other systems (e.g., air filter, spark plugs) are optimized.
6. **No Warranty on Stock Components** The TF-240 itself may come with a limited warranty, but it does not cover wear on stock fuel injectors, sensors, or the ECU. If these components fail, replacement costs will be out of pocket.
7. **Not a Cure for Poor Maintenance** If the bike has neglected fuel lines, clogged injectors, or a failing ECU, the TF-240 will not fully compensate. Basic maintenance (clean injectors, fresh fuel, proper air filter) is still required for best results.
8. **Potential for Overcorrection** In rare cases, improper installation or a malfunctioning unit could lead to fuel starvation or rough idling, requiring troubleshooting or replacement.

### **Ending Conclusion:**The **Total TF-240 Fuel Box Control** is a practical and affordable aftermarket solution for Harley-Davidson owners (1995 2005 EFI Relis) looking to improve fuel efficiency, reduce carbon buildup, and enhance throttle response without major modifications. It is best suited for riders who want a simple, no-frills upgrade rather than a high-performance tuner. While it may not dramatically increase power, it can make the engine run cleaner and more efficiently, particularly in urban or light-duty riding conditions.
For those with well-maintained bikes and realistic expectations, the TF-240 is a worthwhile consideration. However, riders seeking aggressive power gains, advanced tuning, or a full engine rebuild should explore other options. Always research user feedback, verify compatibility with your specific model, and ensure proper installation to maximize benefits.
### **Recommendation:** **Buy the TF-240 if:**- You want a cost-effective way to improve fuel economy and engine cleanliness.
- Your bike is otherwise in good condition with no major electrical or fuel system issues.
- You prefer a straightforward, plug-and-play solution over complex tuning.
- You ride primarily in city or light highway conditions.
**Avoid the TF-240 if:**- You are looking for significant power gains or high-performance tuning.
- Your bike has neglected fuel injectors, sensors, or wiring that need attention.
- You expect dramatic changes in performance without additional maintenance.
- You plan to modify the bike further with other aftermarket parts that may conflict with the unit.
For best results, pair the TF-240 with regular maintenance (clean fuel, fresh air filter, proper oil changes) and monitor its performance over time. If you re unsure, consult with a Harley-Davidson mechanic or experienced aftermarket tuner before purchasing.
