The Torqbyte PM4 fuel pump controller is designed to control high-performance aftermarket in-tank Low Pressure Fuel Pumps (LPFPs), such as the Walbro 450 or DeatschWerks DW400. This module replaces the OEM fuel pump control module (5Q0 906 093) and prevents fault codes.
The TorqVFM PC software enables live monitoring, data logging, and comparison of ECU signals with pump activity. This makes fuel system and tuning problems easy to diagnose. The PM4 offers full closed-loop control of the ECU, regardless of the installed pump, without the need for additional ECU modifications.
