The pulse amplifier is designed to resolve issues with weak or irregular speed signals. In modern vehicles, connecting aftermarket devices directly to a speed signal wire can be problematic, as the signal may be too weak or too heavily charged. This can result in malfunctioning speedometers or trigger engine management system (EMS) warning lights. The pulse amplifier stabilizes the speed signal, helping to eliminate these issues. It also features a built-in frequency divider (dividing by 4) and is compatible with both 12V and 24V vehicles.
