PM4 High Power LPFP Control Module

Description

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. High-capacity aftermarket in-tank fuel pumps generally draw more current than the factory control module was designed to supply. Using high-capacity fuel pumps often overloads the factory LPFP controller and causes it to overheat or overcurrent. This overloading and overheating results in intermittent pump operation, which causes a drop in fuel flow and line pressure as well as dangerous fuel cuts. Torqbyte PM4 provides the best and most effective solution to this problem. Features: Complete Plug-n-Play replacement for the factory Fuel Pump Control Module in late-model Volkswagen Automotive Group vehicles using high-capacity, aftermarket, in-tank Low Pressure Fuel Pumps (LPFPs), such as the Audi TTRS (VAG Part No. 8J0 919 051 E), DeatschWerks DW400, or the Walbro/TIA F90000267/F90000274 (450 LPH), Walbro/TIA F90000285 (525LPH) Interfaces directly with the ECU and eliminates diagnostic trouble codes (DTCs) Fully programmable/configurable pump duty slope control with our easy-to-use TorqVFM PC software Can be used to convert from an OEM brushless pump to one or two brushed pumps TorqVFM software provides live viewing, data-logging, and playback of ECU-commanded vs. Pump-actual duty helping to diagnose ECU tuning or fuel system mechanical issues PM4 is the first and only LPFP driver…
