1.0 Introduction

The Toyota/Subaru GT86/BRZ/FR-S features a flat four configuration engine that employs an
interesting combination of four (4) direct injectors and four (4) port injectors for fuel.  The
ECU must be able to control both types of injector along with accurately control the GDI
pump pressure to a target. GDI pressures operate significantly higher than a conventional
port injection system.

To correctly calculate the fuelling requirements the ECU is able to accept sensor inputs from
the MAF Meter and/or MAP sensor depending on the fuel model mode selected.
