Engine Calibration Modules

Does your throttle feel sluggish, or do you want to adjust the engine's signals without reprogramming the original engine management? Here we bring together plug-in modules from aFe and Injen, both power modules and throttle response controllers, for you who want to change your car's response with a solution that can typically be removed again.

What does a calibration module do?

A calibration module typically sits between the car's sensors or connectors and the original engine management. It can change the signals the engine works from, while the original programming usually stays untouched. In this category you will find, for example, power modules from aFe in the Scorcher series, including SCORCHER HD, GT and BLUE, where the BLUE module features Bluetooth. Injen X-Pedal Pro Black Edition, on the other hand, is a throttle response controller that changes how the pedal signal is translated, typically without changing engine power. More variants can be found under throttle response controllers.

How to choose the right module

• Purpose: Do you want to change the engine's calibration, or is it just a more direct throttle response you are missing?
• Fitment: The modules are typically made for specific car models and engines, so check the part number against your car and not just the car brand.
• Operation: Consider whether adjustment via Bluetooth is important to you, or whether a fixed module is enough.
• Overall setup: The result depends on the car's other modifications. If you want to reprogram the engine management itself, ECU tuning devices are another option.

Installation and inspection

Installation is typically done via existing connectors, but follow the instructions for the specific product. For certain setups a bypass cable is also available, e.g. SCORCHER PRO Bypass Cable, and wiring and other parts can be found under ECU accessories. Whether a modified calibration is legal and can pass vehicle inspection depends on the product and the car. Check this for the specific part number.

Frequently asked questions

What is the difference between a power module and a throttle response controller?

A power module such as aFe Scorcher can change the signals the engine management works from, and thereby the engine's calibration. A throttle response controller such as Injen X-Pedal Pro typically only changes how the pedal signal is translated, so the car feels more direct.

Can a calibration module be removed again?

Often yes, because the modules are typically connected via existing connectors without reprogramming the original engine management. However, it depends on the product, so read the installation instructions for the specific part number before you start.

Can I drive on public roads with a calibration module?

It depends on the product and the car. Check the approval for the specific part number before fitting the module to a car that will be driven on the road. Also be aware that increased power may need to be reported to your insurance company.
