Featuring 4 driving modes and 20 tuning settings, adjust your throttle response to suit your specific needs. Easily installed in under 15 minutes, the EVC is the DIY mechanic’s solution to throttle lag; customisable for any driving terrain or situation, whether you’re on the highway or off the beaten track.

The EVC provides new points of reference for your vehicle’s throttle mapping, modifying the torque request that is sent to the throttle tables in your vehicle’s Engine Control Unit (ECU). As a result, the throttle is activated faster, ultimately reducing throttle lag and enhancing throttle response.


  • Factory Mode: Replicates factory throttle settings, ideal for sharing your vehicle with an unfamiliar driver
  • Ultimate Mode: For enhanced response, choose from 9 available settings to fine-tune your throttle response. Great for towing, overtaking or highway driving
  • Eco Mode: Subdues initial throttle response for greater control on loose or uneven surfaces such as when off-road. Choose from 9 available settings. Great for off-road, heavy traffic and low-speed towing manoeuvres.
  • Automatic Control Mode: Sets the EVC apart from other throttle controllers. AC automatically chooses the ultimate throttle response based on the amount of pedal pressure. Great for long drives or when towing over varying terrains.
