ECU Remapping

Diesel tuning, sometimes called engine remapping or chip tuning, is the process of reprogramming the Engine Control Unit (ECU) in your diesel vehicle. This fine-tuning adjusts settings such as fuel injection timing, turbo boost levels, and throttle response, optimising the engine for greater power, improved fuel efficiency, and enhanced drivability.

Tuning a diesel engine typically involves:

ECU remapping: Reprogramming the ECU to optimise engine parameters.
Hardware upgrades: Installing components like upgraded turbochargers or intercoolers.
Transmission adjustments: Modifying transmission settings to complement engine enhancements.

Diesel cars typically have more torque than horsepower, so they can pull heavy loads without using a lot of fuel compared to a petrol car. That torque, is also why diesel engines are usually heavier and have a shorter stroke than petrol engines, and are the preferred choice in big equipment.

The tuning process for diesel engines works by adjusting the air/fuel ratios, fuel injectors, and ignition timing. By doing this, the engine can produce more torque and power, which can help the car to pull more weight and go faster.

The best vehicles are Diesel, as they are more efficient than their petrol counterparts.

Are you thinking about your car! Let our team assess the current condition of your engine and what kind of performance upgrades your vehicle may need. We’ve tuned hundreds of cars, trucks, and SUVs, so we know what it takes to turn every diesel engine into a masterpiece with our tuning process.

When we start work with your turbo diesel engine, we will connect your car with our computer and testing tools to read the current conditions like:

• Air fuel ratio
• Boost pressure
• Tacho speed & RPM
• and much more

Our technicians do an in depth inspection of your vehicle condition. They also measure all sorts of characteristics, including engine power, fuel economy, cooling system efficiency, general driving ability & notify you, the customer of any issues.

Any engine that has an issue prior to tuning is fixed using the best quality parts with the state of the art and best quality workmanship. We will ensure that the right part is installed to perform its best. Our team goes the extra mile to ensure that your car receives only the best repairs and is repaired to the same condition as factory or better! We then can carry out the diesel tuning service to achieve more torque and more power! Sound good? Contact us to book in!

The goal of Diesel Performance Tuning is to increase the efficiency of your vehicle. With a few simple tweaks, our expert Diesel Mechanics will make your engine run better than ever. The best part is that you don’t need to spend a fortune to do it. A simple remap of the factory ECU can have amazing results without many thousands needed in expensive modifications.

If your truck is in good working condition, we can perform a tune just like we would for a car! By fine-tuning the engine, we enhance its drivability while taking extra care to account for the unique challenges of larger diesel engines, which require expert precision to tune effectively.

At Willy’s Workshop, we’re trusted for restoring trucks to factory-level performance – or better – delivering results you can rely on.

Engine tuners are small electronic devices that help improve the performance of your diesel engine. They attempt to ‘tune’ your engine to your specific needs as a driver. This is not the case at all and for the reasons below do not recommend them, We only recommend a full ecu remapping service.

Tuners are the easiest way to both increase power, fuel efficiency and improve engine performance, Although we do not recommend them at all, as they are not a custom remap to suit your car. We only flash the factory ecu, so we can fully control all of the factory parameters for any particular engine, while still maintaining any safety guards and warning systems. Many of these plug and play tuners trick your car into seeing factory values, while actually pouring fuel into the engine. This will give you a power increase to the vehicle and a perceived increase in torque at the expense of possibly blowing up your engine. We have removed countless piggyback systems after engine failures, and then performed the ecu remapping service at our workshop.

The end result every time is an increase in power, more torque, less fuel and a better turbo diesel vehicle all around. At the same time as the rebuild we can also offer upgrades to improve reliability.

Diesel fuel additives are meant to clean your injectors & fuel lines. They can also help keep your engine running at its best. The most common issue with diesel vehicles is that they don’t get enough lubrication. The additive you add to the fuel will help prevent fuel system issues – especially if you think you may have gotten a bad batch of fuel!  If your engine is having problems, there are other diesel additives to try, such as

• Anti Friction Additives
• Complete fuel system cleaners
• Water dissolvers
• Fuel Stabilizers
• Corrosion inhibitors

As part of all logbook service Willys uses specialised injector cleaners to ensure you get the best life and diesel performance possible.
