APR Fueling - Stage 3+ MPI and LPFP - 2.0T EA888 Gen 3 - MS100111

While the system is essentially plug-and-play with the included mounting hardware and wiring harnesses, the factory ECU is incapable of controlling the new setup without significant modification. APR's Calibration Experts spent months fully recalibrating the factory engine management system to operate with both MPI and GDI injectors. New sensors were added to the system to provide the ECU with accurate closed-loop control, rather than resorting to risky tricks or external controllers. The end result is simple. More fueling headroom and more power!

Description_MKT	The APR Fueling System is a comprehensive upgrade required to safely support Stage 3+ power levels. The upgrade includes a larger in-tank low pressure fuel pump (LPFP) and adds multi-port injection (MPI) to the factory manifold on North American vehicles. Both upgrades are ethanol compatible. All necessary hardware is included for a seamless integration and the system is fully controlled by the factory engine control unit (ECU) thanks to APR's ECU Upgrade.
Description_MKT	Fueling System Overview:
Description_MKT	The 2.0T Ea888 Gen 3 engine uses a returnless, pulse width modulated (PWM) controlled, in-tank low pressure fuel pump that feeds a cam-driven high pressure fuel pump (HPFP), and gasoline direct injection (GDI) injectors. Some models also include multi-port injection (MPI) injectors, which are only used for emissions reasons under light driving. The factory fueling system maxes out at below APR Stage III+ power levels before headroom for safety and longevity decreases dramatically.
Description_MKT	To support higher power levels, the APR Fueling system upgrades several components. First the LPFP is upgraded to a larger, 305 LPH ethanol-compatible unit, mounted inside the factory fuel basket with the included APR mounting hardware. At its inception, the pump is the largest readily available pump of its kind, both physically compatible with the factory fuel basket, and fully compatible with the factory PWM fuel pump controller without additional controllers.
Description_MKT	Next, on North American engines, four, 980cc, ethanol-compatible, Bosch Motorsport MPI injectors, capable of satisfying power levels that outreach those possible with the APR Stage III+ turbocharger system, are added to the factory manifold. All necessary mounting hardware, sensors and harnesses are included, including APR's Fuel System distribution block. The block properly distributes fuel to the newly added MPI injectors and factory GDI injectors, bypassing the tiny MPI injector orifice found on some factory equipment.
Description_MKT	Port injection also brings the welcomed benefit of continuously cleaning the factory intake valves. Due to the lack of fuel spraying on intake valves on direct injection engines, power robbing carbon buildup has plagued their existence since their inception. Since the APR Fueling System brings port injection back to the engine, buildup is greatly reducing, meaning more power, and less labor intensive maintenance!
Description_MKT	While the system is essentially plug-and-play with the included mounting hardware and wiring harnesses, the factory ECU is incapable of controlling the new setup without significant modification. APR's Calibration Experts spent months fully recalibrating the factory engine management system to operate with both MPI and GDI injectors. New sensors were added to the system to provide the ECU with accurate closed-loop control, rather than resorting to risky tricks or external controllers. The end result is simple. More fueling headroom and more power!
Description_FAB	More Fuel and More Power: Provides the required fueling to support APR Stage 3+ power levels.
Description_FAB	980 CC Bosch Motorsport MPI Injectors: Converts the factory injection system to a true, dual, MPI and GDI setup, with large enough injectors to support power levels well beyond APR Stage 3+ power levels for North American Vehicles.
Description_FAB	305 LPH High Flow In-Tank Fuel Pump: Upgrades the LPFP to the largest readily available pump compatible with the factory fuel basket, and PWM controller without additional controllers.
Description_FAB	Proper MPI/GDI Fuel Distribution: The fuel distribution block ensures fuel is properly delivered to the both sets of injectors on North American vehicles.
Description_FAB	Ethanol Compatible Hardware: Fully Ethanol / E85 compatible injectors, fuel pump and associated hardware.
Description_FAB	Cleaner Intake Valves: Performance-robbing buildup on the intake valves, a common byproduct of gasoline direct injected (GDI) engines, is greatly reduced through the cleaning effect associated with port injection.
Description_FAB	Mounting Hardware, Directions and Support: Includes step-by-step instructions and support to for a seamless install with the included plug-and-play wiring harnesses, sensors, mounting hardware, fuel rail, and more!
