PM4 High Power LPFP Control Module

Current TorqVFM Version: v1.1.2 Current PM4 Firmware Version: v1.11    Torqbyte PM4 is an advanced low-pressure fuel pump (LPFP) driver module designed as a complete Plug-n-Play replacement for the factory VAG fuel pump LPFP control module in order to overcome the challenges of increased fueling in VAG returnless direct injection fuel systems where the ECU and the factory fuel pump pulse width modulator (PWM) control module perform closed-loop control of the fuel system line pressure.In the factory configuration, the factory fuel pump control module is only capable of supplying enough current to drive the factory in-tank low-pressure fuel pump the vehicle was originally equipped with.
