Product Description

NZEFI Link G4+ Monsoon Easy Wire Package – Toyota Beams 3S-GE (NA ITB) Engine Specific


For applications requiring a wire-in ECU, NZEFI offers engine management packages that are ‘engine specific’ to suit a range of popular engines. By including an ‘easy wire kit’, essential sensors and accessories as well as a pre-loaded start-up map, these are our most comprehensive engine management solution yet.


This G4+ Monsoon Easy Wire Engine Management Package suits Toyota ‘Beams’ 3S-GE engines transplanted into other vehicles in naturally aspirated (NA) form with aftermarket quad individual throttle bodies (ITBs). It can also be used with the stock intake manifold and a single mechanical throttle body but not the stock electronic throttle body.


This package includes the following items:


  • Link G4+ Monsoon ECU with a ‘start-up’ map pre-loaded into ECU (see notes below for further details)
  • NZEFI Monsoon Easy Wire Kit with 2.5m wiring loom – specifically configured to suit Toyota Beams 3S-GE with supporting documentation
  • Inlet Air Temperature Sensor with connector and aluminium weld-on boss


With the easy wiring kit, all redundant wiring has been removed and additional wiring that is required for the application has been added. All of the required wiring is labelled to further simplify installation. To complete the wiring loom, simply wire up the various power and ground wires and terminate the engine connectors at the required lengths for your installation. The essential connectors required for the engine’s sensors, injectors, coils etc. can either be sourced from a suitable ‘donor loom’, or alternatively, new from NZEFI. Please refer to our Toyota Beams 3S-GE Engine Loom Essential Connector Set for more details.


The NZEFI Monsoon Easy Wire Kit supplied with this Toyota BEAMS 3S-GE engine management package has wiring for the following ECU inputs and outputs:



  • Temperature – engine coolant temp sensor, inlet air temp sensor (+ optional oil temperature sensor)
  • Analogue – MAP sensor in ECU, throttle position sensor ( + optional oil pressure &  fuel pressure sensors)
  • Digital (DI) – starter signal (+ optional vehicle speed sensor)
  • 1 x Crank sensor input
  • 2 x Cam sensor inputs
  • Optional CAN wiring for wideband lambda (AFR) with diagnostic information using Lambda to CAN module



  • 4 x Injectors
  • 4 x Ignition coils
  • 2 x VVTi solenoids (exhaust and intake control)
  • 2-wire idle speed control solenoid (optional)
  • Fuel pump
  • Cooling fan
  • Tachometer or external check engine light (ECU also has a CE Light on the side of it next to the loom connector)
  • Optional CAN wiring for a digital dash


CAN bus wiring (CAN High / CAN Low) can also be included with your easy wire kit as an option. CAN bus wiring is most commonly used for connecting a digital display (dash) that supports communication via CAN such as the Link / Race Technology Dash 2 Pro or Link CAN-Lambda Controller . However, the CAN bus wiring can also be used for other CAN device(s) of your choice.


This input / output allocation has also been configured accordingly as part of the start-up map loaded in the Monsoon ECU.


Start-up map notes:


The G4+ Monsoon ECU in this package is supplied with a start-up map for no extra charge. NZEFI’s start-up maps are created to assist the installer/tuner with getting the engine running. However, these are NOT to be considered a completed, optimised or safe tune and further tuning WILL be required.


The map was originally developed for a naturally aspirated BEAMS 3S-GE engine with standard cams and injectors but can be used as a starting point for any naturally aspirated BEAMS 3S-GE.


Prior to attempting to start the engine all outputs (auxiliary outputs, injectors and ignition) should be checked to confirm their operation and correct wiring by using the test functions built into the ECU and activated via PCLink.


While as much of the ECU configuration as possible has been completed as part of the start-up map,
prior to attempting to start the engine, all inputs (sensors, triggers, switches etc) should be checked and calibrated. In particular it is most important to check & adjust the ‘Trigger Offset’ using a timing light and the VVT Offsets using the test mode in PCLink (see PCLink help for a detailed explanation on these procedures). There is also a calibration procedure for the Manifold Absolute Pressure sensor and the Throttle Position Sensor (TPS) which must be performed.


As the Easy Wire Kit in this package is custom made to order, please allow up to approximately 2 weeks for order fulfillment.
