The Ultimate9 EVC is an electronic throttle controller that eliminates pedal lag in modern drive-by-wire vehicles, giving you instant control over throttle response. Formerly known as iDrive, Ultimate9 rebranded in 2018 and has since become Australia's highest-selling throttle controller brand. At APC4WD, we carry one of the largest Ultimate9 ranges in Australia, with over 2,300 products covering EVC and EVCX throttle controllers, wiring harnesses, mounting brackets, and accessories for a huge range of vehicles.
The EVC is a 100% plug-and-play device that sits between your accelerator pedal and the engine's electronic throttle body. It offers four driving modes with up to 20 adjustment settings, installation takes around 5 minutes with no cutting or splicing, and every unit comes with a lifetime warranty and 30-day money-back guarantee direct from Ultimate9.
What Does an EVC Throttle Controller Do?
Modern vehicles use an electronic throttle (drive-by-wire) instead of a traditional cable linkage. While reliable, this system introduces a slight delay between pressing the accelerator and the engine responding. The EVC throttle controller removes that delay by remapping the pedal signal in real time. It offers four driving modes - Ultimate, Sport, Eco, and Automatic - each with multiple sensitivity levels, giving you up to 20 adjustment settings in the standard EVC and 32 in the EVCX. Whether you want sharper response for overtaking, smoother delivery for towing, or reduced sensitivity for fuel-conscious driving, the EVC puts you in control.
EVC vs EVCX: Which Throttle Controller Should You Choose?
Ultimate9 offers two core throttle controller models. The EVC is the original and most popular option, featuring four driving modes and 20 total settings in a compact unit with a bright digital display. It is 100% plug-and-play, vehicle-specific, and backed by a lifetime warranty. The EVCX builds on the EVC platform with added Bluetooth connectivity, app control via your phone, eight driving modes, and 32 levels of adjustment. The EVCX also includes a built-in auto-start function for supported vehicles. Both models use the same vehicle-specific wiring harnesses and install in minutes.

iDrive vs Ultimate9: Are They the Same?
Yes. iDrive and Ultimate9 are the same company and the same product. The iDrive brand was renamed to Ultimate9 in 2018, and the EVC throttle controller line continued under the new name with ongoing improvements. If you previously owned an iDrive unit or have been recommended one, the current equivalent is the Ultimate9 EVC or EVCX. The product, engineering, and Australian-based warranty support are all the same - just a different name on the box.
Frequently Asked Questions
Are throttle controllers legal in Australia?
Yes. Throttle controllers like the Ultimate9 EVC are completely legal in all Australian states and territories. They do not modify the engine, exhaust, or ECU. They simply adjust the signal between the accelerator pedal and the throttle body, which is a reversible, non-invasive modification. Many new-car dealerships across Australia sell EVC controllers as an optional accessory.
Will an EVC throttle controller void my vehicle warranty?
The EVC throttle controller does not automatically void your warranty. It is a plug-and-play device that can be removed in minutes, leaving no trace of modification. Ultimate9 states that many dealerships sell the EVC as an optional extra. However, warranty policies vary between manufacturers and dealers, so we recommend checking with your specific dealership before installation if you have concerns.
What is the difference between the EVC and EVCX?
The EVC is the standard model with four driving modes and 20 adjustment levels. The EVCX adds Bluetooth app control, eight driving modes, 32 levels of adjustment, and an auto-start feature. Both models use the same vehicle-specific harness and install in the same way. The EVCX is better suited for drivers who want fine-grained control and the convenience of adjusting settings from their phone.
How long does it take to install an EVC throttle controller?
Most installations take around 5 minutes. The EVC is a 100% plug-and-play device. You simply unplug the factory connector on your accelerator pedal, plug in the EVC harness in between, mount the controller to your dash or console, and you are done. No cutting, splicing, or special tools are needed.
