What is DieselTRONIC ECU

If you own a diesel car or SUV, you must know about their power, torque and mileage advantage. But there is a way to take your stock diesel engine to a new level of driving performance with a simple plug-and-play device – DieselTRONIC, an advanced piggyback ECU that has the potential to turn any diesel vehicle into a supercar, in less than 30 minutes. Read on for more details on how DieselTRONIC ECU can benefit your driving experience and have you spending less time at the fuel station.

What is DieselTRONIC used for?

Diesel enthusiasts have long sought to extract more power, BHP, torque and performance from their stock engines. Modifications such as free-flow air filters, rally exhaust headers, polishing the pistons, adding larger turbos and race-derived transmission are some of the popular methods of turning an ordinary car into a beast.

There is also a simple method known as ECU flashing which rewrites the control instructions that the engine provides to the fuel injectors and turbo booster to extract more bhp and torque. However, this alters the manufacturer’s standard parameters regarding torque limits, exhaust gas temperature, turbo kick-in, fuel delivery and ignition timing. This may boost power but there’s no guarantee the engine will last under these conditions. The original ECU would also have to be dismantled which can lead to safety issues.

DieselTRONIC is a game changer in the sense that it is a piggyback ECU that works in perfect harmony with the original ECU, without overwriting its settings. All it does is optimise the engine power, making sure to stay within the manufacturer’s limits so that the warranty is not affected in any way or causing damage to critical engine components.

How Does DieselTRONIC Work Exactly?

Manufactured by RaceDynamics, the DieselTRONIC ECU makes real-time adjustments to engine parameters such as fuel delivery, and turbo boost. Dieseltronic advantages include better performance, high fuel economy and smooth engine operation within safe limits.


DieselTRONIC connects directly to the fuel rail sensor to control fuel delivery timing and duration. The result is that the right amount of diesel is injected into the combustion chamber at the right time depending on various factors that the stock ECU is handling such as throttle position, engine speed, gear selection, etc. With an optimised fuel delivery system, your diesel engine has efficient combustion which gives you an increase of about 30%-40% in power.


Diesel engines rely on turbochargers for that extra boost of power when operating at about 3000-4000 rpm. As the turbo spins, it compresses the air-fuel mixture which enters the combustion chamber at a higher pressure. This gives more power as your engine speed increases. The problem is that power drops drastically when engine speed falls below 2000 rpm as the turbo is not spinning fast enough. At other times it spikes when the rpm is raised and then lowered, leading to jerky performance, or turbo lag. DieselTRONIC connects to the turbocharger boost sensor to avoid all this drama. It manages turbo boost pressure more efficiently, leading to improved performance.

Real-Time Monitoring:

Since DieselTRONIC is connected to the stock ECU, it has access to all engine parameters and can make instant adjustments for smooth driving, high performance, and enhanced mileage. This is done dynamically to deal with real-time driving conditions.

Fuel Efficiency:

With a stock ECU, the more you step on the throttle, the more fuel you consume. DieselTRONIC uses various other factors of engine operation to fine-tune fuel delivery for efficient combustion and reduced smoke emissions from the exhaust.

Driving Modes:

DieselTRONIC comes with 4 different driving modes to suit every driver’s preference. It comes with an economy mode for maximum fuel economy and 2 power modes, 1 for city driving and 1 for highway driving. Drivers can even select stock mode where the DieselTRONIC box does not interfere with engine operation, it’s as if it wasn’t there.

Here are the driving modes explained in more detail:

  • Stock Mode: This setting uses the stock ECU settings and bypasses DieselTRONIC ECU
  • Economy Mode: This setting improves fuel mileage, and engine smoothness with reduced turbo spiking thus saving fuel.
  • Power 1 Mode: Fuel economy is further improved along with a boost in BHP, torque and overall performance. Gear shifts are quicker and jerk-free. Good for city driving.
  • Power 2 Mode: Maximum power and high torque setting for peak performance. Well suited for highway driving.
  • Plug-n-Play Installation: Users can install DieselTRONIC in under 30 minutes without any special tools or mechanical knowledge. It’s as simple as connecting a few wires and you are ready to go.

Is Installing Dieseltronic Safe? Will It Void My Warranty?

Many diesel car owners are concerned about whether DieselTRONIC will void their warranty coverage. But you can be sure that DieselTRONIC is completely safe, doesn’t affect the warranty in any way and provides hassle-free engine power and mileage enhancements without damaging engine components or leading to long-term wear and tear.

DieselTRONIC does not involve permanent modification of your engine. It connects to existing sensors without any physical alterations to components. The plug-and-play nature of DieselTRONIC works both ways, as you can easily remove the device from your vehicle before visiting a service centre. It leaves no trace of installation and is as good as a vehicle with factory settings. Technicians won’t even know that you are enjoying the benefits of DieselTRONIC on daily drives.

Many vehicle owners have reported positive experiences with the use of DieselTRONIC and have not had any warranty-related issues with this tuning piggyback ECU. So, with DieselTRONIC, you can have the best of both worlds, maximum power and mileage along with manufacturer warranty protection.

What’s the Difference Between Single Vs Dual Channel Vs Off Road Dieseltronic?

You can buy DieselTRONIC in 3 different variants, namely single channel, double channel and off-road. Not all vehicles are compatible with these versions, so you will have to check on the DieselTRONIC website for the right model that suits your car.

Here are some of the key differences between the 3 types of DieselTRONIC versions.

1. Single Channel DieselTRONIC

As the name suggests, it can control fuel injectors only and not turbo boost. By optimising fuel delivery and timing, it can enhance power and fuel economy by up to 25% above a stock engine.

2. Dual Channel DieselTRONIC

Dual Channel DieselTRONIC controls both the fuel injector rail and the turbo boost by interfacing with both sensors. So, the result is optimised fuel flow, and injection timing while simultaneously controlling the turbo boost pressure and preventing turbo lag. Drivers will notice a 30% improvement in power and mileage with the dual-channel DieselTRONIC box.

3. Off-Road DieselTRONIC

Designed for use in all offroad vehicles, SUVs and dirt trackers. It offers high performance for navigating rough terrain and extra torque for steep climbing.
