With most overland rigs being heavy beasts and notoriously sluggish, any aftermarket gadget that helps reduce throttle lag and potentially improve gas mileage is worth looking at. Enter the Ultimate9 evcX throttle controller.
Installation: This was a 15 minute install and the only difficulty was unplugging the factory wiring harness from the 4Runner pedal. However, once we had that taken care of, it’s as simple as plugging one end of the Ultimate9 harness into the pedal and the other end into the original factory wiring harness. After that, just run the USC-B cable from the pedal to the dash mounted controller and that’s it. After the install, download the app onto your phone and either key in the last 4 digits of the ID # provided on the wiring harness (or in app, scan the bar code and this will be done automatically).
Ultimate9 evcX Modes:
- Ultimate9 Mode: For maximum throttle enhancement. Ultimate9 mode instantly sets the pedal response to our highest setting.
- Ultimate Mode: Enhance your throttle response and choose from 9 levels of sensitivity to fine-tune your vehicle’s response.
- Launch Mode: Improve those takeoffs with controlled, maximum throttle enhancement. Launch Mode’s initial response is modified compared to Ultimate9 mode to try and reduce wheel spin & increase traction.
- Adapt Mode: Take the guesswork out. Let Adapt Mode choose the best Ultimate throttle response based on your pedal input.
- Eco Mode: Subdue your initial throttle response for greater control on loose, uneven surfaces such as when off-road. With 9 levels to choose from, Eco Mode is great for off-road, heavy traffic and low-speed towing manoeuvres. Try your luck and see if you can gain more economy from your vehicle!
- Anti-Slip Mode: Reduce your throttle response and limit your RPM to help increase traction. With 9 levels of sensitivity, gain more control when navigating slippery surfaces such as snow, ice and mud.
- Valet Mode: Designed for parking, Valet mode reduces throttle response whilst limiting the available throttle to provide approximately 50% maximum RPM.
- Factory Mode: Replicates factory throttle settings, ideal for sharing your vehicle with an unfamiliar driver
- Lock Mode: Add an extra level of security to your vehicle. Block all throttle input from the accelerator pedal and immobilise your vehicle.
With the engine turned on, you can connect via Bluetooth into the app. Once in the app scroll around the mode dashboard with each mode change updating instantly to the Ultimate9 controller.
Our Take: Every driver and vehicle is unique, and that’s exactly why the flexibility and adjustability of the Ultimate9 EVCX stand out. On long highway drives, Econ Mode makes perfect sense—boosting fuel efficiency by at least 10%, making the device pay for itself in no time.
Need instant throttle response? Ultimate9 Mode drastically reduces lag, giving your vehicle a noticeable boost. For everyday driving, we’ve found Adapt Mode to be the sweet spot—it intelligently adjusts to your driving style for the best overall results. And for security, Lock Mode disables the throttle pedal entirely, adding an extra layer of protection for your rig.
Bottom line: The Ultimate9 EVCX delivers on its promises. It’s an affordable, worthwhile upgrade that enhances performance and can quickly pay for itself. Every driving condition from pavement to off-road or snow and ice, demands a different level of throttle response and the Ultimate9 provides the options required for an improved driver experience.
