Ultimate9 EVC Throttle Controller - EVC171L
The Ultimate9 EVC Throttle Controller is an award-winning (SEMA 2018 Global Media Award) throttle response controller designed to eliminate throttle lag and enhance your vehicle's acceleration. Compatible with modern fly-by-wire throttle systems, the EVC provides new points of reference for your vehicle's throttle mapping, modifying the torque request sent to the throttle tables in your Engine Control Unit (ECU).
Key Features
Advanced Control Modes
- Ultimate Mode: 9 adjustable settings for enhanced throttle response, from smooth everyday driving (1-3) to sportier acceleration (4-6) to maximum performance (7-9)
- Economy Mode: 9 dampened throttle settings for improved fuel economy and enhanced traction control in off-road or low-speed situations
- Automatic Control Mode (AC): Intelligent set-and-forget mode that learns your driving style and adjusts throttle response in real-time
- Normal Mode: Replicates factory throttle settings, essentially turning the EVC off
Technical Specifications
- Display: LED Digital Display with Blue LED Colour
- Drive Interface Dimensions: 49mm (L) x 31mm (W) x 8mm (H)
- Compatibility: Works with both automatic and manual transmissions
- Installation Time: Quick 5-15 minute installation
- Settings: 20 total adjustable settings across 4 driving modes
- Voltage Pattern: Internal settings adjust voltage patterns for different transmission types
How It Works
The EVC throttle controller works by providing new points of reference for your vehicle's throttle mapping, introducing either a sharper or flatter throttle curve depending on the selected mode. By modifying the voltage signal from the drive-by-wire pedal assembly, it reduces the "dead zone" and throttle lag, bringing the throttle in earlier throughout the pedal stroke.
Installation & Compatibility
The EVC plugs directly into your vehicle's accelerator pedal command module, making installation possible in as little as 5 minutes with no tools or vehicle modifications required. The system is vehicle-specific and customized for each make and model to ensure optimal performance.
