It was designed to be a complete Plug-n-Play, drop-in replacement for the OEM fuel pump PWM control module. PM5 is used to provide increased fueling in returnless direct injection fuel systems on upgraded EA825 setups.\u003c\/p\u003e\n\u003cp\u003ePM5 is capable of continuously supplying the OEM fuel pump with up to 40A of current.\u003c\/p\u003e\n\u003cp\u003eWhile the PM5 increases the capacity of the OEM fuel pump, its electronics interface directly with the ECU ensuring no diagnostics trouble codes are generated. Torqbyte's innovative technical approach built into the PM5 allows the ECU to maintain full control of the aftermarket LPFP operation and maintain the closed-loop fuel pressure control mechanism that the vehicle was originally designed with. This crucial feature is something that _none_ of the other LPFP \"upgrades\" currently on the market are able to offer.\u003cbr\u003e\u003cbr\u003eBecause it interfaces directly with the ECU, PM5 is able to live-stream the ECU commanded duty as well as pump actual duty, over USB, to a laptop running the free Torqbyte TorqBLPM Windows software.
