FAQ

Yes, you can. While the input reading tops out at 5V, it is compatible with 12V/16V on and off signals, such as those from a 2-step button.

A FuelTech ECU (Engine Control Unit) is a sophisticated electronic device designed to manage and optimize the performance of internal combustion and electric engines. Our ECUs are known for their advanced features and versatility, making them popular in motorsports, water sports, and high-performance automotive applications. Compatible with 1-12 cylinder and 2-4 rotor engines. Key features include:

1. Engine Management: Controls fuel injection, ignition timing, and other critical engine parameters to ensure optimal performance and efficiency.

2. Tuning Flexibility: Allows for extensive tuning and customization to meet the specific needs of different engines and performance goals.

3. Data Logging: Records vital engine data such as RPM, temperature, and pressure, which can be analyzed to improve performance and diagnose issues.

4. Boost Control: Manages turbocharger or supercharger boost levels to maximize power output and prevent engine damage.

5. Traction Control: Helps maintain traction by adjusting power delivery based on road conditions and vehicle dynamics.

6. Advanced Diagnostics: Provides detailed diagnostic information to help identify and troubleshoot engine issues quickly.

7. Nitrous Control: Integrates with nitrous oxide systems to manage the delivery of nitrous for increased power output.

8. Ignition Control: Optimizes ignition timing for better combustion and performance.

9. Fuel Injection Management: Precisely controls fuel injectors to ensure the correct air/fuel mixture for optimal engine performance.

10. Delay Box Integration: Supports delay box functions for drag racing applications, allowing precise control of launch timing.

11. Staging Control: Manages staging processes to ensure consistent and effective vehicle positioning at the start line.

12. Shifting Control: Automates and optimizes shifting for improved performance and consistency, particularly in sequential and automatic transmissions.

The biggest difference in any level of FuelTech ECU is the number of input and output channels. While all models share the same core functionality, the deciding factor is whether you can fit your required inputs and outputs on the model you are interested in.

Inputs are signals the ECU reads or monitors. Examples include:

• 2-step button
• Oil pressure
• Engine temperature
• Driveshaft RPM

Outputs are signals the ECU controls or activates. Examples include:

• Fuel injectors
• Ignition coils
• Transbrake solenoids
• Fans
• Fuel pumps

To choose the right FuelTech ECU for your needs, follow this rule of thumb: make a list of all the inputs and outputs you will need, leave some room for future expansion, and then check the ECU comparison chart to see which model fits best.

We offer several specific software variations available for download through the FTManager software. These variations are approved by many sanctioning bodies to ensure compliance with the rules of various racing classes.

FuelTech ECUs are commonly used in carburetor and mechanical injection combinations. In these setups, while they don't manage fueling, they still offer a wide range of functionalities, including acting as a delay box, data logging, and controlling ignition, nitrous, lean out timers, boost, and shifting. Essentially, FuelTech ECUs can handle everything on the car except for fueling.

No, almost any type of trigger can be set up and used with a FuelTech ECU. While missing tooth triggers are preferred for their faster starts and superior trigger resolution, regular 4 magnet crank triggers are still a very common and effective option.

Yes, the full range of delay box features are in every ECU.

No, the mini switch panels rely on CAN communication with the ECU, so if the ECU is not powered, the switch panel will not have any control.

Yes, FT550, FT550LITE, and FT600 can control dual drive by wire throttles.

No, almost any type of trigger can be set up and used with a FuelTech ECU. While missing tooth triggers are preferred for their faster starts and superior trigger resolution, regular 4 magnet crank triggers are still a very common and effective option.

As long as you have an MSD box or similar device to run the coil, you can retain the distributor and manage all timing and rev limiter functions with the FuelTech ECU. This includes 2-step, 3-step, rev limiter, launch retards, and more. Everything you need is integrated into the system.

A SparkPRO racing ignition module is designed solely to enable the use of 2-wire "dumb" coils. While it doesn't increase the ignition energy of a standard coil, it allows for the use of OEM 2-wire coils. This is particularly beneficial for engines with limited space or unique coil placement, such as sportbikes or modern Hemis.

Low impedance fuel injectors require an external injector driver, high impedance injectors do not. If you are unsure if your injectors are high or low impedance, you can check your injector’s specifications or use a multimeter. To determine impedance with a multimeter, disconnect the injectors from the wiring harness and measure the resistance between the positive and negative terminals of the injector. Low impedance injectors are typically around 2-4 ohms and high impedance injectors will be around 12-16 ohms.

A 10 ft wiring harness is ample for any car with a standard front-engine configuration. For rear-engine applications, such as a VW Bug, Toyota MR2, or most dragsters, a 20 ft harness is typically more suitable.

Yes! You need one conditioner per O2 sensor. So if you plan to run 8 O2 sensors, you will need 8 Nano or NanoPRO units.

No, the original Nano is only compatible with the Bosch LSU 4.2 sensor. The NanoPRO, however, supports a variety of sensor options, including Bosch 4.2, 4.9, 5.2, and the NTK alcohol sensor.

No, many high-level RWD drag applications rely solely on a driveshaft speed sensor and engine RPM for a pre-plotted power management curve. However, for any kind of active control with a slip percentage target, it's recommended to have both front and rear wheel speed sensors.

Any Windows-based laptop will work. Higher-end models may load the software and open multiple logs faster, but any Windows-based laptop will function properly.

Yes! We offer regular classes at our facility in Ball Ground, GA. These classes cover basic wiring and tuning fundamentals. Additionally, we provide an advanced factory training session where you can bring your race car for personalized, one-on-one training with our expert staff on our Mainline hub dyno.
