FAQ

1. What are the benefits of a diesel tune?

A diesel tune can significantly increase horsepower and torque, improve fuel efficiency, enhance throttle response, and optimize overall engine performance. It can also help optimize the vehicle for specific uses, such as towing.

2. Is a diesel tune safe for my engine?

When performed correctly by a reputable tuner like Willys Workshop, a diesel tune can be safe. Custom tunes that are tailored to your vehicle's specifications will optimize performance without compromising engine reliability. However, it's essential to avoid generic, poorly designed tunes that could potentially damage your engine.

3. How much power can I gain from a diesel tune?

Power gains vary depending on the specific engine and the tune itself. However, many diesel tunes can increase horsepower and torque by 20% or more, resulting in a noticeable improvement in acceleration and pulling power.

4. Will a diesel tune affect my fuel economy?

In many cases, a well-designed diesel tune can improve fuel economy, particularly during normal driving conditions. By optimizing the engine's combustion process, a tune can help your engine operate more efficiently, leading to better fuel consumption.

5. Can I install a diesel tune myself?

Some tuners, like Edge Products and Bully Dog, offer user-installable programmers. However, for custom tunes and more advanced configurations, it's best to have a professional, such as the skilled technicians at Willys Workshop, perform the installation and tuning process to ensure optimal results and engine safety.

6. What are the different types of diesel tuning?

Diesel tuning includes many methods, like remapping the engine control unit (ECU), using a plug-and-play module, or even complete engine rebuilds. Remapping is usually done by connecting to a vehicle's Onboard Diagnostics (OBD) port, and by adjusting the various parameters. Plug-in modules offer a quick alternative, while complete engine work focuses on upgrading the mechanical components.

7. How long does a diesel tune take to install?

The installation time varies. A plug-and-play tuner can often be installed in less than an hour. Custom tuning, especially if done on a dyno, may take several hours or even a full day to ensure the tune is perfectly optimized for your vehicle.

8. What should I consider when choosing a diesel tuner?

Consider the tuner's experience, customer reviews, the level of customization offered, and the warranty support available. A reputable tuner like Willys Workshop will offer custom tuning, excellent customer support, and a commitment to quality. Research and ask plenty of questions.

9. Do diesel tunes void my warranty?

Yes, some diesel tunes can void your manufacturer's warranty. However, custom tunes, such as those provided by Willys Workshop, are often designed not to overwrite the vehicle's ECU settings—reducing the risk of voiding your warranty.

10. Can I revert back to the stock settings after a diesel tune?

Yes, most tuners allow you to revert your vehicle back to its stock settings if needed. This is an essential feature, particularly if you need to take your vehicle in for service or if you need to comply with emissions regulations.

11. What tools do I need to perform a diesel tune?

This depends on the type of tune. For plug-and-play tuners, you may only need the tuner itself and basic hand tools. For custom tuning, you might need a laptop with tuning software, an OBD-II connection, and potentially a dynamometer, done by experts such as Willys Workshop.
