What Are The Stage 2 Remap Hardware Requirements?
To carry out a stage 2 remap, which is a more advanced level of engine tuning, certain hardware upgrades and requirements are essential to ensure the vehicle can handle the increased power and performance levels safely and efficiently. The most common hardware upgrades for a stage 2 remap include:
High-Flow Air Filter
Generally, the hardware prerequisites include a high-flow air filter to enhance the engine’s breathing. By optimising the airflow to the engine, you get a better air-fuel mixture, which can lead to a more efficient combustion process. This, in turn, can result in a noticeable increase in horsepower and torque, giving the vehicle a slight edge in performance whilst also potentially improving fuel economy and efficiency.
Intercooler Upgrade
Depending on the specific vehicle and its existing setup, it might also require upgraded intercoolers to maintain optimal temperatures. When you remap an engine to increase its performance, the turbocharger often works at a higher pressure, generating more heat. The existing intercooler might not be sufficient to cool this increased volume of hot air to the optimal temperature. An upgraded intercooler can handle this higher level of heat, maintaining the right temperature balance and ensuring that the engine receives cool, dense air for combustion.
Exhaust System Upgrade
A more advanced exhaust system facilitates a smoother and more efficient exit route for the exhaust gases that are produced during the combustion process. This is achieved through a larger diameter of the exhaust pipes and a more streamlined design, which reduces the back pressure and allows the gases to flow out more freely, reducing the strain on the engine. By allowing the engine to expel exhaust gases more efficiently, it creates a better air-fuel mixture, which is vital for achieving optimal combustion and, consequently, better performance and fuel economy.
Exact requirements can vary between cars, so it is always best to consult with a professional car remapping service such as the one we offer here at Viezu to determine the hardware upgrades necessary for your vehicle. It is an intricate process where each change is tailored to harmonise with the vehicle’s existing systems, ensuring a seamless upgrade that elevates performance while maintaining safety and reliability.
What are the Expected Performance Gains from a Stage 2 Remap?
The expected performance gains from a stage 2 remap can be substantial, but they depend on the specific make and model of the vehicle, as well as the quality of the hardware upgrades installed. Generally speaking, you can anticipate the following enhancements:
Increased Horsepower and Torque
A stage 2 remap often unlocks a significant boost in both horsepower and torque, offering a more responsive and powerful engine. It is not uncommon to see power gains anywhere from 20-50 BHP (Brake Horse Power) or even more, depending on the vehicle’s initial performance metrics.
Enhanced Throttle Response
The throttle response becomes more immediate and crisp, providing a more connected and engaging driving experience where the vehicle responds swiftly to the driver’s inputs.
Improved Fuel Economy
While the primary focus is on augmenting performance, a well-executed stage 2 remap can potentially lead to much-improved fuel efficiency, especially during highway cruising, as the engine can operate more efficiently with the upgraded components.
Better Over-Rev
The engine can rev higher and more freely, offering a broader power band and enhancing the vehicle’s performance during overtaking and high-speed driving.
Optimised Air-Fuel Ratio
With a more advanced air intake and exhaust system, the engine can achieve an optimal air-fuel mixture, facilitating a more efficient combustion process and unlocking additional performance gains.
Sportier Exhaust Note
Upgrading the exhaust system not only aids performance but can also give the vehicle a more robust and sportier exhaust note, adding to the exhilaration of driving.
