The amplifier improves the acceleration of a car and overcomes the problems occurring during overreacting. The amplifier measures the signals from the acceleration pedal, calculates the change of the angle of the potentiometer of acceleration speed (angular speed) and multiplies the signals from the acceleration pedal by a value which is determined by the angular speed of the potentiometer of the accelerator pedal. Additionally, the amplifier includes a function of a cruise control, which can be controlled with a single control switch. ## Claims ### Claim 1 A retrofit device for a vehicle with an electronic accelerator and an electronic control unit, said retrofit device for improving the acceleration of said vehicle, said retrofit device comprising: a first connector configured to be connected to said electronic accelerator and configured to accept input signals from said electronic accelerator, said input signals indicating a position of said electronic accelerator;
