Common-rail Diesel ECU Remapping Improves Performance

Common-rail Diesel ECU Remapping Improves Performance – Any automotive manufacturer will not show the true performance of the cars they put out. Of course, this is for passenger cars or general use in the community. Usually, they will only issue the standard power of the machine. Well, remapping ECU is a way to bring out the peak performance of your car engine.

Electronic Control Unit (ECU) is a component that will work to regulate and control the vehicle engine. Usually, each manufacturer already has a setting for each car. So every vehicle that comes out has the same standard engine control for the same capacity in one manufacturer.

What is an ECU Remap?

We can say that this ECU will be the center of the regulation of activities that occur in the car. In this regard, the ECU has a function equivalent to the Central Processor Unit (CPU) on a computer. In the process of working, the ECU will receive input from various sensors on the engine. The ECU then processes data from these sensors before the actuator receives a command from the ECU based on the processed data from the sensor.

ECU remap process is the process of increasing engine power from standard to higher conditions – Common-rail Diesel ECU Remapping.

The ECU will receive all data and information from the vehicle system. For example, such as how much gasoline is needed by the engine, the air needed by the engine, the engine cooling system, to the driving character of the driver.

It is true that every manufacturer does limit the machine with the aim of the safety of the driver. If the manufacturer does not limit it, the engine will issue the maximum performance that the engine can produce. This can really harm the driver when on the road. This is where the idea of ​​an ECU remap emerged for some users who didn’t want their vehicles to be standard vehicles.

The purpose of remapping the ECU itself is to change the settings on some parameters related to engine control or tuning in cool terms. Changes in these settings are intended so that the engine can improve performance from the standard version. For example, the range of the maximum engine performance value is from 1-10, then the vehicle standard is usually only in the 7th range. Well, there are still 3 levels left. These three levels are actually the target of the ECU REMAP. Although not up to a value of 10, increasing from 7 to 8 is very different from the power that comes out of the engine.

Remapping the ECU really does give an optimal power boost. Or at least the power we want. For example, a Toyota car with a diesel engine coded 2KD-FTV with an engine capacity of 2,500 CC, 4-cylinders has a default power of 104 hp. After tuning, the machine was able to generate power up to 120 hp or an increase of up to 16 hp. This is certainly able to make the engine power greater than the factory default settings.

This great power can affect fuel consumption as well. For example, the car previously had a fuel consumption of 1:13 km/liter. After the remap, the fuel consumption gets better to 1:15 km/liter. This is one of the results of our remap.

Well, before finally deciding whether to remap the ECU or not, let’s see what the other advantages are first.

Power Boost

When the ECU has been remapped, the power that will be released by the engine will be boosted. The increase varies from 10 to 30% depending on how we remap the ECU.

On paper, this increased power can be directly felt through a much fiercer acceleration. Torque at lower engine speed will feel more ‘grabbing’ than before the ECU remapped. So the effort of the engine to move the car body becomes smaller. That’s why remapped cars tend to have a fairly large bottom torque.

Those who like large torque, of course, will feel excited by this power boost. The car will feel easier to bulldoze various road terrain thanks to a large power surge.

Efficient Fuel Consumption

As I mentioned a little above, fuel consumption will be more efficient. This is one of the advantages of the ECU remap on the car. Many people suspect this is because the increase in power and torque is quite pronounced. The effect is that the driver does not need to step on the gas pedal deeply to get the ideal speed.

However, we must also know that this fuel consumption is only 3-10% more efficient, aka not too significant. However, those who often travel far will feel the difference.

Then is it enough to provide peak performance of an engine? The answer is no. Remapping ECU is the first step to increasing peak engine performance. There are several things we must do to achieve that peak performance.

Optimize Common-rail Diesel Engine After ECU Remapping

After tuning the chip in your machine, what should you do? In addition, you can optimize the capabilities of the common-rail diesel engine by replacing some engine hardware parts with aftermarket goods. The following is about the details of any items.

Air Filter

Starting from the most basic, you can maximize the air supply. You do this by replacing the standard air filter with an aftermarket version. However, the type of air filter is divided into two, the first is a replacement. Options for air filter replacement such as K&N, Ferrox to Sarang Racing.

An open filter type air filter is available. The increase in power is also quite significant when using an open filter type. Like the K&N Typhoon series, which can increase power up to a range of 3-6 HP.

Downpipe

The downpipe is the pipe that connects the engine and the exhaust. The goal is to improve the flow of fuel to the exhaust. In addition, a catalytic converter device is also included in this component.

Locally made downpipes are indeed the most in-demand because they are affordable and the quality is not inferior to the aftermarket version. For example, the Kansai and Super Turbo downpipes are now available for Toyota diesel engines.

Exhaust set

After the downpipe, the exhaust channel can also be maximized. This exhaust channel starts from the center pipe to the muffler. The goal is to maximize exhaust flow after passing through the downpipe Generally ranging from 6-8 hp.
