The Torqbyte PM4 fuel pump controller has been developed to control high-performance aftermarket in-tank low-pressure fuel pumps (LFPFs), 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 it easy to diagnose fuel system and tuning issues. The PM4 offers full closed-loop control from the ECU, regardless of the pump fitted, without the need for additional ECU modifications.
