Introduction
Before we discuss throttle controllers, let’s first rip off the bandaid: A throttle controller will not increase your vehicle’s horsepower or torque.
However, these little devices will improve your driving experience and your vehicle’s capabilities, so they’re quite useful.
If it won’t increase the power, but it will improve the capabilities of a vehicle, what does a throttle controller actually do?
How Do Throttle Controllers Work?
Before we integrate throttle controllers into the picture, let’s break down the drive-by-wire/fly-by-wire system that most 4×4 vehicles utilise.
In a fly-by-wire system, by pressing on the gas pedal, you’re not opening the throttle directly. Instead, there’s a position sensor connected to the end of the accelerator pedal, which sends the signal to the ECU (Engine Control Unit) for use Windbooster Coupon. The signal is then sent to a motor that spins and opens up the throttle.
The throttle position sensor sends a “controlled”/ramp-up signal to the ECU, meaning that, no matter how hard you push the accelerator pedal, the position sensor will take a few seconds to ramp up before it tells the ECU to open the throttle up fully. This is better known as accelerator lag, and that is exactly where a throttle controller comes into play.
A throttle controller comes in between the position sensor and the ECU. It works exactly like an in-line tuner, in that it receives the signal from the sensor, intercepts it, and then sends different information to the ECU. Essentially, a throttle controller “controls” the signal sent from the throttle to the ECU. This is exactly why it feels like a throttle controller increases horsepower; it doesn’t, but it does increase your vehicle’s 0-60 time.
Do Throttle Controllers Really Work?
Throttle controllers really do work. They might not increase your vehicle’s power, but they’re extremely advantageous. An EVC throttle controller will give you much better control over your vehicle, as well as any situation you find yourself in.
The Pros of Throttle Controllers
The throttle controller makes your 4×4 very versatile, and much more capable than it was before.
A throttle controller set to deliver the maximum amount of power instantly will help your vehicle tow heavy loads easier than before.
A throttle controller doesn’t only help with delivering power to the wheels sooner. You can also dial down the settings to the point where your vehicle is using only 50% of the engine’s power, even with the gas pedal fully pressed down. In muddy or sandy situations, you’ll find it much easier to control your vehicle and the way it behaves, instead of spinning the wheels in place.
Another advantage of a throttle controller, and one of the biggest reasons 4×4 enthusiasts buy them, is for off-roading. By dialling down the settings, your gas pedal input won’t be nearly as aggressive as usual. This is immensely helpful in tight spots and on bumpy roads.
Additionally, an EVC throttle controller has adjustable presets loaded into the device. Presets such as the economy mode or the ultimate mode will come in handy during your driving adventures.
The Cons of Throttle Controllers
There is only one relatively significant con to throttle controllers, and it’s an issue on some models only.
Certain throttle controller models will make you “lose” half of the gas pedal. What we mean is that, if you’re holding down the pedal to halfway only, the throttle controller will send a 100 percent signal to the ECU. A vehicle cannot push more than 100 percent of its power, so pressing down the gas pedal more than 50 percent will be meaningless. This might shorten your 0-60 time and improve your vehicle’s acceleration tremendously, but it will make driving much, much more difficult and less enjoyable.
So, which throttle controller should you purchase to avoid this major disadvantage?
EVC Throttle Controller (formally known as iDrive Throttle Controller)
EVC throttle controllers from Ultimate9 (formerly iDrive) are some of the highest quality throttle controllers on the market for 4×4 vehicles. They’re so far ahead of the competition that it’s difficult to find a quality throttle controller that’s not made by Ultimate9. What makes them so great?
First of all, EVC throttle controllers are very simple to install. It shouldn’t take you more than 5 minutes to install the unit into the gas pedal assembly. Additionally, they don’t require any re-wiring.
Ultimate9 are specific to a model vehicle; they might cost a few more bucks, but they will deliver the best results. By being model vehicle specific, the unit will reprogram pedal mapping in the best way possible for that specific model.

Throttle Controller Modes
What we love about EVC throttle controllers is that they usually come with four adjustable presets, or modes. The ultimate mode is made for performance and towing because it sharpens the throttle response. Thanks to the 10 adjustability levels, the throttle will be sharp to your liking, but it won’t lose its full distance.
The economy mode, as the name suggests, is economical and fuel-efficient. This mode is also excellent for off-roading and driving on sandy or muddy roads. The throttle becomes dampened in this mode, which will help you get out of tight spots easily.
The automatic control mode monitors your driving behaviour and adjusts the throttle response as necessary. It changes the settings based on how hard you’re pressing the accelerator. There’s also a normal mode, which returns your vehicle to factory pedal mapping.
There’s one more advantage EVC throttle controllers have over controllers from other manufacturers. EVC throttle controllers are “woken up” by a quality tuner – a vehicle modification that improves performance by optimising different engine parameters. In essence, you’ll feel a much more significant difference from a tuner with an EVC throttle controller.
If you decide to look for a throttle controller from other manufacturers, keep in mind that regardless of how great a throttle controller is, it will not increase your horsepower – so do not be fooled by any marketing which says it will.
