The factory LPFP sits in a basket submerged in the vehicle's gas tank. The pump operates off of a pulse-width modulated (PWM) signal sent from the pump's control module, which is mapped in the ECU. As fueling demand increases and decrease, the PWM signal adjusts to send only the required amount of fuel through the pump. Unfortunately upgrading the LPFP is not a simple drop in task. The pump's factory enclosure presents some packaging constraints limiting clean expansion to a larger unit. Likewise, doing so often results in overheating and subsequent protective shut down of the factory control unit as it's operating outside of its intended design. This is even true when installing larger and expensive factory units like those found on high output vehicles, such as the Audi TT RS and RS3. Furthermore, upgrading the LPFP control module with the matching expensive higher output control units present other issues as the controller receives CAN messages from integrated vehicle componentry not common on vehicles requiring an upgraded LPFP.
