ECU Tuning Your Trucks? Find More Ways Here to Save On Fuel Costs

Are you looking at new ways to save on fuel costs in your fleet? Many businesses have turned to ECU tuning or other methods, but which is the best way to truly save on fuel? At Cartrack we want you to have all the information to help you make the best decision for your business. 

So keep reading to find out how ECU tuning and other methods help you save on fuel.

1. Does ECU tuning increase fuel economy?

Yes, ECU tuning can increase your vehicle's fuel economy. It does this by fine-tuning air-to-fuel ratios, turbocharger boost, and throttle response. These all work together to reduce unnecessary fuel consumption and make your vehicles operate more efficiently

2. When will ECU tuning not work?

ECU tuning will not work if your car doesn’t have a turbocharged engine. Another reason tuning won’t work is if your vehicle’s manufacturer has placed anti-tuning software or an anti-tamper lock on the vehicle's computer. Additionally, if your vehicle is already experiencing serious mechanical issues, you won’t be able to tune the ECU.

3. Is ECU tuning worth it?

ECU tuning can be worth it. It can make your vehicle perform better and use less fuel. However, it does come with considerable risks that you must consider. First, it will probably void your vehicle’s warranty, and second, your insurance is less likely to cover you in an accident or engine failure.

4. How to improve fuel economy in a truck?

If you’re looking to improve fuel economy in a truck, you can do the following things:

  • Monitor and improve driver behaviour
  • Keep your truck well maintained (tyre pressure, air filters, oil levels, etc.)
  • Don’t overload your trucks on their hauls

5. How to increase horsepower and fuel efficiency?

To increase your vehicle’s horsepower, you can tune the ECU in your vehicle. To improve fuel efficiency, you should improve your driving behaviour, keep your vehicle well maintained, and take out any unnecessary weight in your car.

6. Can a fleet system really help you save on fuel costs in your trucks?

Yes, a fleet management system can definitely help you save on fuel costs in your trucks. An FMS provides you with driver behaviour monitoring, route optimisation and predictive maintenance, all of which can reduce your fuel costs. Additionally, Cartrack’s MiFleet system can reduce your fuel costs by up to 15%. It matches fuel spend with telematics, removing manual errors and easily picking up fuel misuse.

7. What are the other ways to achieve fuel savings?

There are plenty of ways you can achieve fuel savings. The number one way is through good driver behaviour. Speeding, harsh braking and excessive idling all waste fuel. Other things you can do are:

  • Keep your vehicle maintained
  • Use GPS navigation to get the best routes
  • Remove unnecessary weight or drag
  • Switch to an electric vehicle
  • Carpooling

8. What are the benefits of tuning your trucks?

The benefits of tuning your trucks are that you can improve their performance and you can improve their fuel efficiency.

9. What causes a truck to consume more fuel?

A truck will consume more fuel if drivers drive aggressively and idle excessively. Not keeping trucks regularly maintained and overloading them also increase fuel consumption. Poor route selection also contributes to higher fuel usage.

10. Why is driver behaviour critical to fuel economy?

The way your drivers handle your vehicles directly impacts fuel usage. If your drivers are:

  • Revving a cold engine
  • Braking harshly and cornering
  • Speeding
  • Accelerating too quickly
  • Idling unnecessarily

they increase fuel consumption and accelerate wear and tear.

11. Why is my truck getting such poor fuel mileage?

If your truck is getting poor fuel mileage, it’s likely due to poor maintenance. Issues like clogged fuel injectors, air filters, oxygen sensors, fuel filters, airflow sensors, worn pistons, brakes, ignition parts, and underinflated tyres all reduce fuel efficiency.

12. How much is a fleet fuel management system?

A fleet fuel management system from Cartrack starts at roughly R1 699. However, get in contact with one of our sales consultants for accurate pricing, as fleet size and requirements affect cost.
