EVolution Classic Controller ID Guide

EVolution uses three distinct controller models in their classic model vehicles. It's crucial to identify which controller your vehicle has because each model requires specific equipment that is not compatible with the others. Using the correct cable and software for your controller is mandatory—these components are not universal, and mixing them is not possible.

The transition from Curtis controllers to EVolution-branded units took place between late 2021 and early 2022. In mid-2023, EVolution introduced another model labeled as "C". This new model can utilize the same cable as previous EVolution-branded controllers but does require different software compared to earlier controller models.

1. Locate the controller

The controller in the Classic model is located under the seat behind the batteries. There is a black plastic access hatch that can be removed to make getting at the controller much easier. It is held down with 4 plastic rivets.

 

2. Access the controller

The rear access panel needs to be removed to gain access to the controller. To remove the panel the 4 plastic push rivets need to be removed. Carefully remove them, depending the age of your vehicle they may be brittle and could even break. Should you break one, replacements can be purchased at any local auto store or local hardware store, they are inexpensive. This may be more difficult to get access to on vehicles with a back seat or sweater basket installed.

4. Identify The Controller - EVolution Branded Controller

The EV48-400 and EV48-400-A models are identical in terms of programming, while the newer EV48-400-C model, often referred to simply as the "C" model, requires different software than the two earlier models. It is important to know which model is in your vehicle to ensure you are using the correct equipment to establish a connection.
