TFSI & TSI Low Pressure Fuel Pump Control Unit
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)
Is the first and only LPFP driver solution on the market that lets the ECU perform complete closed-loop control of the requested fuel system pressure regardless of what aftermarket LPFP is used. Want to run a 23A, 525LPH Walbro F90000285 E85 pump under full control of the ECU? PM4 will let you do that. The ability to use any aftermarket LPFP, while keeping the ECU in complete control of its operation, is a key distinguishing feature not available with any competing LPFP solution
Supports big turbo setups by removing the traditional LPFP fueling bottleneck and permitting the fuel system to hold any ECU-requested pressure
A truly scalable solution. A single PM4 can drive two LPFPs in parallel Regardless of the preferred fuel system configuration, the ECU retains complete control of the low-pressure fuel system's operation
