What is car performance tuning and why is it important? Gee Diesel Services Ltd provide diesel performance tuning throughout Nottingham, Bassetlaw, Broxtowe and Nottinghamshire. Find out more about the types of car engine tuning and the benefits of car engine tuning.
What Is Car Tuning?
Car tuning is an enhancement or adaption of a vehicle with the goal of having it operate as the driver requires. In essence, it outlines how a car is modified to improve one of its functions. Tyres can be changed to increase traction, and engine parts can be altered or replaced to increase power. Off-road vehicles can be lifted by modifying the suspension, if space is needed between the floor and the engine. The practice of improving a car's performance to meet user demands is known as tuning.
Some people can be impatient when tuning, which can lead them to utilise the wrong parts. It's imperative to balance the core functions of a vehicle's performance. These are acceleration, manoeuvrability and deceleration. By increasing engine power, flaws in the handling or braking system that were undetectable can now be seen. Engine tuning entails changing or tweaking an internal engine or its Engine Control Unit (ECU) in order to maximise performance and increase the engine's effectiveness, robustness, or production of power.
From simple engine overhauls to frequent carburettor and ignition system adjustments, tuning can include a wide range of modifications and alterations. As part of performance optimisation, several design decisions made during the engine's development may need to be changed. Regular tune-ups are necessary to ensure that the automobile runs as it should. In general, modern engines require a few tune-ups during the course of a ten-year, or 250,000 kilometres (160,000 mi) lifespan.
Types Of Car Engine Tuning:
Chip Tuning
Replacing the ECU chip with a new one is called "chip tuning". It's a quick and simple method of tuning. However, it doesn't offer as much customization as other methods. Chip tunes consist of a box or chip that's linked to the ECU via the OBD2 port or into the wiring harness through the engine compartment.
A fresh ECU map that is pre-loaded in it will alter the vehicle's characteristics. These features can enhance power, fuel efficiency, torque, and more, depending on what your chip provides. Chip tuning can change the stock ignition timing, the air/fuel ratio, and the boost levels.
For instance, the chip can instruct the ECU to add more air and fuel to the cylinder. When the bigger air/fuel combination ignites, the combustion will be much larger, increasing the engine's output.

Chip tuning offers a plethora of advantages to your car, such as providing faster acceleration, greater power, and more torque. Most chips may increase performance over standard by up to 30%. Additionally, because of the increased torque provided by chip tuning, you may change up a gear early and save gasoline by up to 15%.
Other advantages include getting rid of the original speed limitation, not having to raise the gearbox and even having warm-up times that stop the car from accelerating until the engine is warmed up. When you weigh the cost of a chip against the other advantages, buying one seems like a no-brainer.
OBD Tuning
OBD tuning is accessing the ECU through a diagnostic port and making changes to its settings. Although it needs specialised equipment, this technique offers greater customization than chip tuning. There are several methods to optimise the ECU while remapping. Connecting to the ECU can be done in three different ways: through the OBD port, on a bench, or while in boot mode. The most frequent and well-liked tuning technique is OBD reading and writing.
It has completely transformed the market by opening up tuning to a larger audience. The "onboard diagnostic port" (abbreviated "OBD") is used to access the ECU from within the car. It resides near the glove box or under the steering wheel. It enables quick and simple fault diagnosis which helps identify issues. This is done by searching the engine control unit for codes.
Many individuals are unaware of OBD, a performance improvement. Consider it as an optional tweak that you can request. The aim is to make sure that your automobile receives the highest possible engine specs. If you don't tune your car to its highest capacity, you'll discover that it will be squandered.
ECU Remapping
To optimise the ECU's settings, the software for the ECU must be modified. The most customizable choice, it also has the potential to improve engine performance. Only a trained expert should execute the adjustments to ensure that they are made.
Remapping used to include "chipping," or removing the old ECU from the automobile and installing a new one. Since then, technology has advanced. The factory ECU that comes with your automobile can be rewritten.
The OBD can be used to access the chip in this situation. For security reasons, several contemporary automobiles may limit access via the OBD. The ECU must then be removed and attached to an external computer in such a situation.

An alternative is to use an external ECU. The ECU of a car controls many vital components, such as airbags, locks, braking, and engine response. These are all key components and can have disastrous consequences if they're changed from their intended state. Engine remapping can alter how engines behave while you're driving. This is because the car will perform exactly how you want it to. ECU remapping can also increase a vehicle's power and torque.
Benefits of Car Engine Tuning:
Improved Fuel Efficiency
By remapping and tuning your ECU, you can improve your fuel economy and lower your expenses. By altering the ECU, you may reduce the amount of petrol your engine uses and increase engine performance. You have three options: increase the ignition timing, decrease the idle speed, or use less fuel.
Depending on your driving patterns and the state of the roads, ECU tuning and remapping can save fuel consumption by up to 20%. Increased fuel economy is another benefit of making engine modifications to vehicles. By altering the ECU to adjust the fuel injection time and air-fuel ratio, auto engine tuners can increase fuel economy. In the long term, this can help you save money.
Increased Horsepower & Torque
One of the major benefits of tuning and remapping is that you may increase the power and torque of your engine. By adjusting the ECU settings, you may bring out all of your engine's potential and increase its responsiveness and agility.
Your engine should have between a 5% and a 40% boost in horsepower and torque. Although the quality of the tune or remapping will determine this. If you enjoy accelerating and moving quickly, this may change how you feel when driving.

Better Throttle Response And Acceleration
The acceleration and throttle responsiveness of a car's engine may both be improved. Car engine tuning can improve the engine's reaction to the accelerator by modifying the ECU.
This leads to more rapid acceleration and improved overall performance. As a result, you can accelerate quicker and have more control over your car's performance.
Enhanced Engine Sound
Improved engine sound is a further advantage of automobile engine tuning. Car engine tuners can enhance the exhaust of an engine to make it sound more powerful by modifying the ECU.
Your car will sound better and be more interesting to drive as a result, which may enhance the whole driving experience.
Increased Engine Lifespan
Last but not least, adjusting an automotive engine may increase engine longevity. Engine pressure may be lowered by tuning a car, which over time leads to less wear and tear. It maximises the engine's performance by doing this. Your engine will run longer and require less maintenance as a consequence, which may help you save money. Remember that how you drive and how you maintain your car will have a big impact on how long the engine lasts. This implies that your engine is more susceptible to wear and damage the more you use and misuse it.
Additionally, it can easily sustain early damage if not maintained regularly. Remapping a car increases the engine's power and torque outputs, without affecting the engine's lifespan. The length of time your engine survives depends on how you drive and how well you maintain it. Given the increase in power and torque, expect the engine's lifespan to decline more if you drive your car aggressively. It will fail sooner if you don't get regular maintenance performed on it. For this reason, it's important to practise safe driving habits and maintain your car regularly after a remapping.
