Since 1872.
At its core, modern engine tuning involves reprogramming the software that controls the engine’s behavior. This computer, known as the ECU, manages vital functions such as:
You cannot tune an electric motor for "more power" easily without voiding the battery warranty. However, you can "tune" the inverter and motor controller. This changes throttle mapping (pedal response), regeneration braking force, and top speed deration. Tesla tuners (like Ingenext) sell modules that plug into the CAN bus to disable torque limits and unlock "Drift Mode" on dual-motor cars.
(2023): Discusses how technologies like Variable Valve Timing (VVT) and turbocharging are critical for modern high-efficiency strategies.
Tuning ranges from simple ECU recalibration to full mechanical overhauls (cams, forced induction, etc.).
It is not dying, but it is being locked down. Modern ECUs (Bosch MG1, MED17) have encrypted firmware. Tuners must "bench unlock" the ECU by opening the box and soldering wires to the circuit board. Some manufacturers (Toyota, new GM) are making this nearly impossible.
Tuning is fun, but it has real consequences. You are removing the safety margins the manufacturer built in for the worst-case scenario (bad gas, 120°F desert heat, abusive driving).
