If you've made it this far, you've most likely heard of the term Piggy-back, and want to better understand what it is and how it works.
Piggy-Back, contrary to what many may deduce, is not the same thing as REMAP, or electronic reprogramming. In fact, these two methods are different and each of them has its own advantages and disadvantages.
With this in mind, and the doubt that these two terms generate in many people, we decided to prepare exclusive content to explain what is piggy back and how it differs from reprogramming, as well as what its processes and advantages are.
Therefore, if you are trying to understand better about the subject, continue reading to answer your questions!
What is Piggy-Back?
To begin our explanation of Piggy-back, let's start with the obvious: what is it and how does it work?
The Piggy-Back is nothing more than an external power module. In other words, a module that can be installed in a vehicle in order to make changes to its operating parameters.
Basically, Piggy-back is a method that works to intercept the signals that your vehicle's engine constantly emits during use, changing these signals and sending this information that will be modified directly to the ECU (Electronic Control Unit), or Electronic Injection Center.
Just for the sake of understanding, the ECU is the “computer” present in cars, which is responsible for processing the information and commands made with the car, in order to control the electronic injection system.
By sending the changed signals to the ECU, this computer is able to dictate new and different operating parameters for the engine. For example, performing fuel compensation, giving greater turbo pressure, etc. In the end, the main result of a Piggy-back is the gain of torque and power for the vehicle.
What are the advantages of Piggy-back?
The first big advantage of the Piggy-back is that the module can be reused later in other vehicles. In other words, you buy the module and can reuse it when you change cars.
Furthermore, this type of module leaves no traces within the vehicle's software, not even in the engine control unit and hardware.
Because of these two main advantages, the Piggyback is usually a great alternative for cars that are still under warranty.
Another benefit of Piggy-back is the possibility of making changes to driving modules (Sport/Eco/Race).
Finally, Piggy-back helps maintain full injection integrity (both software and hardware). Furthermore, it is possible to remove it without the need for inspections and revisions, and guarantees total safety to the propeller, as it keeps the system within a closed loop.
How does it work?
The Piggy-back is often called “Power Chip”. This method, in short, works in the form of a device that helps manipulate signals from sensors and actuators within the electronic injection (ECU).
Thus, the ECU can continue to control the vehicle's entire electronic injection system perfectly. But, with the piggy-back, it compensates for the differences that the power chip requests, in order to generate the intended gains, such as increased torque and engine power.
What the power chip will do is make some changes to the actuator signals, in order to take the signals to the values that were previously programmed.
What is the difference between Piggy-back and REMAP?
Good! Now that you understand what Piggyback is, you may be wondering what the difference is between this method and electronic reprogramming.
REMAP, which is the most used term when we talk about reprogramming a vehicle's electronic control unit, acts by changing its calibration parameters.
Comparing with the piggy-back method, the main difference between the two models is precisely the fact that REMAP is made from a direct change in the software. While the Piggy-back changes the signals sent to the ECU.
However, REMAP can offer slightly higher performance, as reprogramming can be carried out within the system, eliminating barriers.
On the other hand, carrying out a REMAP is a practice with some risks, as these changes made to the system can affect unwanted parts, such as the engine protections themselves and electronic injection control locks.
Additionally, altered signals can be compensated for by the ECU as time passes. Thus, the effects of Piggy-back can be mitigated or eliminated by the system self-correcting to maintain factory defaults. As remap changes these parameters directly in the ECU code, its effect is long-lasting.
Conclusion
Overall, both methodologies are options for those who want to increase their car's power. And the most important thing is to choose reliable services to avoid any of these advantages and risks that we mention here.
Remap offers greater control, security, earnings and customization. However, not all remaps are the same; It is essential to rely only on experts to change a system that is so crucial to the performance and safety of your vehicle.
