APR Fueling System Upgrade

APR Presents the 2.0T EA888 Gen 3 Fueling System!

System
System System

The APR Fueling System is a comprehensive upgrade required to safely support Stage III+ power levels. The upgrade includes a larger in-tank low pressure fuel pump (LPFP) and adds multi-port injection (MPI) to the factory manifold, both of which 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.

Quick Facts

  • More Fuel and More Power
    Provides the required fueling to support APR Stage III+ power levels.
  • 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 III+ power levels.
  • 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.
  • APR Stage III+ ECU Upgrade
    Upgrades Stage III to III+ with the necessary and complex ECU calibration changes necessary for accurate, closed-loop control of the fueling system, without the need for risky ECU tricks or external controllers.
  • Proper MPI/GDI Fuel Distribution
    The fuel distribution block ensures fuel is properly delivered to the both sets of injectors.
  • Ethanol Compatible Hardware
    Fully Ethanol / E85 compatible injectors, fuel pump and associated hardware.
  • 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.
  • 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!

Fueling System Overview

System System
System System

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 roughly APR Stage III power levels before headroom for safety and longevity decreases dramatically.

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.

Next, 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.

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!  

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!
