Acceleration adjuster for vehicles with an electronic accelerator

A vehicle having an electronic accelerator with a first connector, an electronic control unit with a second connector, and an acceleration adjuster, said acceleration adjuster comprising:

• a third connector complementary to said first connector, said third connector configured to accept input signals from said electronic accelerator, said input signals indicating an actual position of said electronic accelerator;
• a fourth connector complementary to said second connector, said fourth connector configured to provide output signals to said electronic control unit, said output signals indicating a transformed position of said electronic accelerator;
• and
• circuitry electrically coupled to said third connector and said fourth connector, said circuitry configured
• to receive said input signals from said third connector,
• to provide said output signals to said fourth connector,
• to calculate a rate of change in position of said electronic accelerator based on said input signals, and
• to generate said output signals by multiplying said input signals by an amount that is functionally dependent on said rate of change in position of said electronic accelerator;
• and wherein
• said first connector is connected to said third connector;
• said second connector is connected to said fourth connector;
• and
• said second connector is complementary to and adapted to engage said first connector.

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 an actual position of said electronic accelerator;
• a second connector configured to be connected to said electronic control unit and configured to provide output signals to said electronic control unit, said output signals indicating a transformed position of said electronic accelerator;
• a user interface configured to receive input from a user and to generate user input signals indicative of particular ratios of a second value represented by the output signals to a first value represented by the input signals
• means for determining a rate of change in position of said electronic accelerator;
• and
• means for generating said output signals based on said input signals, said user input signals, and said rate of change in position of said electronic accelerator.
