OK for Tuning sake or what we call tuning. If you look at it in the same way as an ICE setup the answer is No, electric vehicles do not require tuning like traditional gasoline-powered vehicles do. They do not have an engine or combustion system that needs to be adjusted or fine-tuned. The performance of an electric vehicle is controlled by its battery, motor, and software systems, which are all pre-programmed and do not need regular tuning. Maintenance for electric vehicles typically involves inspecting and maintaining the battery and motor, as well as updating the software as needed.
But if you look at it with respect to the button on the dashboard allowing you to enter into an ECO mode setting or when your battery is low it will reduce the delivery/power to the motor the answer would be yes.
All manufacturers in the same way they do with an ICE setup will build the system to be economical and prevent damage to the system which makes things last longer.
If we look at the Renault Kangoo E-Tech which has a small 44kwh battery and a 90Kwh motor which is probably geared to suit the needs. So if you modify the software that controls the delivery of power to the motor to be more or less then you can either improve performance or increase economy and the life of the vehicle. Now like ICE setups, the manufacturer does not recommend and even voids the warranty if you tamper with the ECU software in any way. But many people do flash the ECU with new firmware and change configurations to give better performance and economy.
At the moment ECUs are being listened to, decoded and software built to emulate, recode and replace what the current software provides.
Even if you look at a EV ECU it looks very similar to a ICE ECU.
