Torqbyte PM4 fuel pump controller, Audi VW VAG MQB

Heavy-duty controller for all low pressure fuel systems that run upgrade fuel pumps like Walbro, Bosch, DW or similar high output units.

Stock LPFP controller is known to be very limited, the wiring isn’t designed for the increased power draw of the big fuel pump, nor is the controller itself. Therefore tuner often needs to limit the output of LPFP electronically from the software, to avoid issues such as constant fault codes, or even the dangerous overheating of the LPFP controller.

With Torqbyte, you can use 100% of your fuel pump, and max out your stock pump safely as well to begin with. Unit comes pre-calibrated for your car ready to run, but is also fully adjustable with the free Torqbyte software via USB cable. You can set the PWM curve, output and other parameters to fit your unique setup.

Our recommendation for LPFP upgrade for most of the MQB platform vehicles is the Precision Raceworks LPFP set.
