What is Car Tuning?

In earlier days, Car Tuning was only associated with people who were involved in car racing because they were the only ones who needed to tune their car’s performance in order to enhance their efficiency.

However, things have changed and car tuning has become quite popular over the years and the reason could be that people want to increase the performance of their road cars as well.

Basically, what you do with Car Tuning is enhance the ECU settings and parameters of your car in order to get better performance.

With Car Tuning, you can increase the performance, handling, and even response of your car. On top of that, you can make your car fuel-saving with the help of Car Tuning. Those who don’t want the performance of their cars also do car tuning in order to make it fuel-efficient.

Engine Control Unit or ECU is where your car’s engine’s performance is electronically handled. ECU is also the main controller of your car’s engine as to how much it produces and delivers power. You must have heard that the car is delivering linear power, this is exactly what it means.

It is most often seen that Car Tuning is done at the factory to meet different drivers’ needs and requirements but we have seen that some experienced professionals tune their own car as well.

To tune a car as per your liking, you will first need to access input tables of the car’s ECU and for that, you need to install an automotive tuner software which we have already mentioned above.

For example, we take MaxxEcu mTune as our Car Tuning software then we first need to pick the best laptop for car tuning, download the software and then install this software on our laptop.

It is worth noting that picking the right laptop for car tuning plays a very important role in how your car is tuned so you should not hesitate in spending the right amount on the device.

If you don’t have experience in Car Tuning then it is best to take help from others. For this, ask a professional to tune your Car or get help from your mechanic friend.

After that, look for a road which is deserted or has very limited movement of vehicles because we will have to perform our test runs on this road.

Pick a road where you can do full throttle runs without any problems as well as roads where you can go over the speed limit of 50-60MPH.

Ensure that there is no one living nearby the roads because car tuning and doing test runs is risky so you need to avoid as much risk as possible.

Take a street sign as your starting point and then begin an ECU+ capture by asking your friend to do the same. Lug the vehicle along the road using second gear. Make sure that the RPM of your car is very low. Take note of this RPM.

Once you pass the street sign, floor the accelerator and apply full power. Accelerate up to the redline and then coast back down. Save the capture and get off the road.

Repeat this until you are satisfied that you have consistent torque and horsepower. It is important to cool down the vehicle as well in between captures. There is an overlay function inside your car tuning software that can be used to display different dyno graphs on top of each other.

In this way, you can compare the different captures and see how your test runs are performing. If you see consistent numbers, start altering a few things. Assess the changes that you made are negative or positive by looking at the horsepower.

Do this a few times and tweak the vehicle to its maximum torque and horsepower. It is also important to pay attention to the captures for signs such as lean mixture or retarted times during runs.

You can also modify the fuel efficiency of your vehicle using the same software by doing some necessary tweaks to its HP and Torque.

For example, you can limit the amount of fuel that is delivered to the engine and reduce the ignition timing to make the engine more powerful. We have also made a list of all the software apps we recommend for car tuning along with their software compatibility:
