The practice involves remotely optimizing a vehicle’s engine control unit (ECU) through electronic correspondence with a tuning specialist who uses HP Tuners software. For example, a vehicle owner might send data logs recorded from their car to a tuner, who then modifies the ECU parameters and sends a revised calibration file back to the owner for installation.
This method provides a convenient and accessible way to enhance vehicle performance, improve fuel efficiency, or address specific drivability issues without requiring physical visits to a tuning shop. Its origin stems from the increasing sophistication of aftermarket tuning software and the widespread availability of internet connectivity, enabling remote collaboration between tuners and vehicle owners worldwide.
