What is FN Tuned Throttle Response Controller?

Modern vehicles do not have a physical throttle cable like they used to. Modern cars and trucks use an electronic throttle control system (ETC). This means the car’s computer (ECU) is in control of your throttle. With electronic throttles, you no longer have complete control over how fast your throttle responds. So, you can’t just mash the pedal harder to accelerate faster.

What’s even worse is manufacturers use the “one size fits all” method to make the majority of customers happy. We thought that was Fn Ridiculous; not every driver is the same, so why should every vehicle’s throttle map be the same? This idea is how Fn Tuned was born! Fn Tuned gives you the customization you deserve by giving you complete control over the throttle mapping. With 36 sensitivity settings and an Anti-Theft mode, Fn Tuned is guaranteed to improve your vehicle's performance and security, giving you more enjoyment and peace of mind.

How Does FN Tuned Work?

Nowadays, vehicles are built with more advanced technology than they used to be. The vehicle’s computer now controls the systems that were once mechanically controlled. One of the new systems is drive-by-wire, or Electronic Throttle Control (ETC), an automotive technology that replaced the mechanical linkage connecting the accelerator pedal to the throttle. The typical drive-by-wire system has Three main components: (1) an Accelerator Pedal Model, (2) a throttle valve that opens and closes the electric motor, and (3) a powertrain/engine control system (PCM/ECM). These features allow for pedal placement flexibility, reduced weight, and help improve fuel economy. But ETCs have their limitations.

The main disadvantage of the ETC is that the pedal response time is significantly slower due to the manufacturer’s settings. The ETC determines how MUCH the throttle body will open and how FAST it will open. So when you press the gas pedal down fully, some manufacturers' throttle bodies will only open to 80% and all of them will open at a speed the computer thinks is best. This is how acceleration is controlled and limited in ETC vehicles. Our engineer says it doesn’t matter how quickly you floor the gas pedal; there will still be a lag in your throttle response.

This is what Fn Tuned is built for! Fn Tuned plugs directly into the Accelerator Pedal Position Sensor (APPS) located on the gas pedal. Fn Tuned then takes the information from the APPS and sends it up to 1000 times faster to the ECU and throttle body. By doing this, Fn Tuned gives you the ability to eliminate the throttle delay from your accelerator (gas pedal) and allows your engine to respond faster. The difference is Fn unbelievable!
