ECU remapping, also known as chip tuning, is the process of modifying a vehicle’s electronic control unit (ECU) to improve performance, power, and efficiency.
The stages of remapping
The “steps” of engine remapping don’t exist as a service/upgrade that you can purchase. They are simply terms that have been used to group a wide variety of modifications. Common groupings used for the various remappings are:
. Phase 1 Remapping
Stage 1 remapping is a critical step where the engine’s basic parameters are changed using the ECU software to improve its performance. This is like giving the car a basic tune-up so that it runs efficiently and smoothly.
. Phase 2 upgrade
Stage 2 is where more detailed adjustments are made using hardware upgrades. The goal is to fine-tune the engine to significantly improve performance while ensuring it remains safe and reliable. This is about finding the sweet spot for the car to deliver powerful performance without putting excessive strain on the engine.
. Phase 3 upgrade
Stage 3 Remap is where the engine is optimized to its full potential, involving numerous hardware upgrades to achieve maximum power and the best possible efficiency. This stage is for those looking to get the most out of their vehicle’s potential power, pushing it to its highest limits while maintaining safety and reliability. This is where the car becomes the best version of itself, delivering unmatched performance and a truly exhilarating driving experience.
What is a Level 2 Remapping?
Stage 2 engine chip tuning involves fine-tuning the engine control unit (ECU) as well as the necessary hardware upgrades to improve the vehicle’s performance. The goal, for example for a professional tuning company performing this process, is to increase the vehicle’s power, torque, and overall driving experience while maintaining safety and reliability. It is a tailored approach that takes into account the vehicle’s characteristics to achieve optimal results.
What are the hardware requirements for Level 2 Remapping?
To perform a Level 2 remap, which is a more advanced level of engine tuning, certain hardware upgrades and requirements are essential to ensure that the vehicle can handle the increased power and performance levels safely and efficiently. The most common hardware upgrades for a Level 2 remap include:
. High-flow air filter
Typically, hardware prerequisites include a high-flow air filter to improve engine breathing. By optimizing the airflow to the engine, you get a better air-fuel mixture, which can lead to a more efficient combustion process. This results in a noticeable increase in power and torque, giving the vehicle a slight performance advantage, while potentially improving fuel consumption and fuel efficiency.
. Improved intercooler
Depending on the vehicle and its configuration, it may be necessary to upgrade the intercoolers to maintain optimal temperatures. When reprogramming an engine to increase performance, the turbocharger often operates at a higher pressure, which generates more heat. The existing intercooler may not be sufficient to cool this increased volume of hot air to the optimal temperature. An upgraded intercooler can handle this higher heat level, maintaining the proper temperature balance and ensuring that the engine receives cool, dense air for combustion.
