What is engine tuning - Your complete guide

Engine remapping or engine tuning is a relatively low-cost way of boosting the performance, power, and the driveability of a vehicle. Though most tune-ups or remaps focus on increasing the power and performance of your vehicle, it is also possible to enhance your vehicle engine's fuel efficiency with proper remaps. Now, you may think and ask yourself, is remapping really worth extra bucks though? Well, here's an article that will give you a detailed idea about car remaps.

What is ECU remapping or engine remapping?

Engine remapping is the process when the OBD port or the on-board serial port of a car often known as the ECU or the electronic control unit is adjusted or modified with new software settings to affect its performance and overall behavior.

From the factory, a wide range of vehicles will not have the maximum potential and capabilities of their engines unlocked to use, even in the sports cars. Electronic control units or ECUs generally limit the performance of the engine to improve fuel consumption, reliability, and emissions.

Similarly, your vehicle's engine may be limited also to ensure it can deliver proper balance of the outright performance and fuel consumption on different road conditions and temperatures like in regions where the weather is extremely hot when engines usually generate less power.

Remaps usually are done to unlock the maximum power and potential of an engine by modifying and adjusting some of the ECU parameters and settings, removing the restrictions set by the manufacturer.

How does engine tuning work?

An engine tune-up is performed by overwriting or rewriting the new software program or modified software program onto the electronic control unit or the ECU of the engine. This is a pretty simple method of improving your car's overall performance and driveability that's usually done by plugging just a laptop into the OBD port of the car. Just to let you know another thing that this is the same plug that most garages use for diagnosing any problem with a vehicle if it breaks down.

Of course, it is not as easy as downloading a software online and then doing it all by yourself. You will definitely need reliable and professional remappers for this. The new software will be customised and modified based on your driving requirements and the make and model of the car and you will get optimised behavior and improved performance after the remaps.

What are the advantages of engine remapping?

• It is a low-cost way of enhancing your vehicle's performance and fuel efficiency. Tuning prices may vary but overall it is the most affordable option when it comes to improving a vehicle's driveability and performance.

• You do not need any kind of physical upgrades: - You do not need to go for any kind of physical upgrades or replacements to make your car perform better. In fact, it is the way around. Plenty of aftermarket parts may need an engine tune-up to ensure they are working well.

How much can it cost you to get your car remapped?

Aa with several performance upgrades, a tune-up may cost you as much or as less as you are willing to invest for your car servicing. Often tune-ups are offered in different kinds of packages and in different stages.

The most reasonable remaps are the stage 1 remaps or upgrades and are generally done with a little programming for minor performance boost. And this usually may cost you somewhere around a few hundred dollars.

On the other hand, stage 2 remaps may need a little more effort and work to the engine, generally, some exhaust improvements and new air filter installation. This will naturally add up to the cost.

Stage 2 remaps are the most crucial ones and need more effort and work as compared to the first two stages of remaps. Stage 3 remapping includes some critical and major engine upgrades like new internal components such as pistons installation, new turbo systems installation, etc, to extract the maximum capabilities and higher performance from your vehicle. And these may cost you thousands of dollars, though still it is cheaper than any physical replacements or part changes.

Hope, now you have a clear picture of ECU or engine remapping. Every car owner or car enthusiast must get their vehicles remapped at least twice a year to increase the engine's power and performance, and ensure a smoother and comfortable driving experience.
