Frequently Asked Questions
What is throttle lag?
Modern vehicles are equipped with electronic pedals rather than traditional cable throttles that had a direct physical linkage to the throttle. The cable throttle was more rudimentary but also more efficient, you pushed the pedal and the throttle responded. Any delay was usually due to a slack cable or an out of tune carburettor.
In a modern throttle system (also known as drive-by-wire or fly-by-wire), pedals rely on sensors to measure the action of how far and how fast the driver pushes the pedal, this action creates a torque request which is sent to the Electronic Control Unit (ECU). The ECU then sends this request to the Throttle Position Sensor (TPS) which adjusts the butterfly position and actuates the throttle accordingly.
Throttle lag is the dead spot you feel in top top 5-10% of pedal travel where nothing happens. You hit the gas, there is a noticeable hesitation and then the throttle responds. This in an inherent electronic lag that is programmed from factory and which physical input (i.e. stomping your foot harder) cannot overcome.
Why do cars have throttle lag?
There's a number of reasons why modern cars have throttle lag.
- First of all, compromised drivability. Car manufacturers need to tune their vehicles from factory to suit a range of different drivers and driving styles. The factory tune for a new car is not overly aggressive, it's not overly underwhelming, it kind of just sits in the middle, to try and tailor for the wide variety of potential customers they may have.
- There's also issues along the lines of emissions testing, each manufacturers vehicle must meet strict emissions testing prior to being released. A part of the emissions testing procedure is a snap acceleration smoke test which monitors smoke opacity at different rev ranges, so if a vehicle is producing too much pollutants at certain RPM's the manufacturer may need to restrict the vehicles performance.
- Manufacturer fuel economy claims. We all know the fuel efficiency claims by car companies are almost impossible to replicate, however somewhere along the line they do have to provide evidence of their figures. If a car manufacturer cannot get decent fuel efficiency figures with a new prototype vehicle or updated model, they may have to restrict the performance of the vehicle to improve fuel efficiency figures. Part of this restriction could potentially be dampening the vehicles factory throttle response.
How does the EVC Throttle Controller work?
The EVC is a throttle response controller that gives you complete control over the responsiveness of your vehicle.
The EVC does this by providing new points of reference for your vehicles throttle mapping, either introducing a sharper or duller throttle curve depending on what mode/setting you have the EVC on. The EVC sits in between your pedal assembly and factory pedal plug, overriding your factory set throttle parameters and proving its own parameters to your vehicles ECU.
Introducing a sharper throttle curve (Ultimate Mode) sharpens your throttle response, bringing the throttle in quicker and getting rid of the lag from when you hit the gas and the throttle responds. Ultimate mode 2-3 is perfect for everyday driving, while Ultimate mode 5-8 is great for towing, overtaking, hill climbing, sand driving, charging through a bog hole etc. where you need to stay on the gas and power through.
Introducing a duller throttle curve (Economy Mode) dampens your throttle response passed factory levels and is great for low traction situations where more finesse control over the power application to the wheels is required, such as rock crawling, water crossings etc. Economy mode 2-3 is perfect for when you need a less aggressive response and don't want to be constantly spinning the wheels.
Why can't I just push my foot down harder?
Your factory pedal has set parameters, these parameters cannot be overridden by physical input i.e. pushing your foot harder or faster. It doesn't matter how fast you push your foot down, your factory parameters will always deliver the same throttle response.
The only way to alter your throttle response is to electronically override it by adding new sets of throttle parameters with the EVC, to get to wide open throttle at a faster rate.
By introducing a sharper throttle curve with the EVC in Ultimate Mode, you are modifying the torque request that is sent through to the throttle tables in your vehicles ECU, this in turn actuates the throttle faster. While the EVC doesn't add top end HP, it does improve acceleration ramp up power which is the amount of accessible power when you plant your foot, from either a stopped start or rolling speed.
Likewise, with the EVC set to Economy mode you are introducing a duller throttle curve and dampening your throttle response passed factory levels. This is also something that your foot cannot do as it doesn't matter how lightly you ease the throttle on, you are still guided by your factory set parameters.
Without electronically overriding these parameters there is no way for you to physically alter your vehicles throttle response, throttle mapping or throttle actuation.
Is the EVC Throttle Controller safe to use?
The EVC is 100% safe to use.
As part of the EVCs’ development we ensure the EVC cannot override any of a vehicles safety functions or parameters.
We also test the EVC on every new vehicle model to ensure that the current model EVC works effectively with any late model vehicle, whether it is a revised, updated model or completely new vehicle release.
The EVC is also backed up with a lifetime replacement warranty which also extends to your vehicle and covers any costs that arise from the installation and use of your EVC.
That is how confident we are in our product and as far as we know we're the only throttle controller company in the world that offers this level of product cover, confidence and peace of mind for their customers.
Will the EVC Throttle Controller impact my new car warranty?
The EVC, like any aftermarket accessory (bull bars, snorkels, driving lights etc.) can potentially impact your new car warranty if it has caused the issue you are seeking warranty on.
At Ultimate9 we back our products 100%, that is why we offer a lifetime replacement warranty with every EVC Throttle Controller sold. This warranty also extends to the vehicle the EVC is installed on. So, if our product does cause an issue on a customer’s vehicle, we will cover any costs involved under our own comprehensive liability insurance.
As far as we're aware, we are the only throttle controller company in the world that offers this level of warranty to its customers.
Can the EVC Throttle Controller be used with other performance products?
The EVC can be used with any ECU Tune, Dyno Tune, ECU Remap, Power Chip or ECU Reflash as the EVC works on a different internal system and if anything will complement the positive effects of other aftermarket performance modifications.
The benefit of the EVC is its adjustability, with 4 driving modes and 20 adjustable settings you can fine tune your throttle response to any driving style or situation. This enables you to also manually adjust the strength and effectiveness of your other performance accessories with the EVC.
If your custom tune/chip/remap is great for everyday driving but lacks a bit of punch when towing, you can use the EVC to sharpen your throttle response and compensate for the extra added weight behind your vehicle.
On the flip side, if your tune/chip/remap is too aggressive when driving off-road or in wet conditions, you can use the EVC to dampen your throttle response and have more finesse control over the application of power to your wheels.
Is the EVC Throttle Controller good for towing?
The EVC is a throttle response controller that gives you the power to tune your vehicles throttle response for any towing application or situation.
The EVC Throttle Controller does this by providing new points of reference for your vehicles throttle mapping, allowing you to either sharpen or dampen your vehicles throttle response.
Sharpening your throttle response has a range or benefits for towing, by getting rid of low-down lag and having a sharper take off you're able to get up to speed quicker and with less effort, improving the overall towing ability of your vehicle.
On the flip side, dampening your throttle response is also very handy in a variety of towing situations. By softening your throttle you can have a far more controlled application of power to your wheels which is great for any low speed towing manoeuvres where you don't want to be jerking on the throttle every-time you hit the gas and potentially overcorrect yourself.
Will the EVC increase my fuel consumption?
Fuel consumption largely comes down to how you drive with the EVC Throttle Controller installed. Generally speaking around 50% of our customers get far greater throttle response with no impact on fuel economy, around 40% get better economy along with far greater throttle response, while a small percentage see slightly worse fuel economy (usually due to a heavier right foot from the extra throttle response!).
The beauty of the EVC Throttle Controller is the 30-day money back guarantee, so you have 4 weeks to try the EVC out for yourself risk free and can return the unit if you're not 100% satisfied, we'll even pay for shipping.
