The Link G4+ Xtreme. Powerful engine management for high end applications and ideal for V8s with eight ignition and fuel outputs. 

Flexible options over the control of inputs and outputs allow the user to design their own functions to control all sorts of devices. Precise control of injectors and ignition angle are guaranteed at very low or high RPM or manifold pressures. A very high level of protection from interference and tolerance of trigger input errors has been built into this ECU, ensuring a smooth running engine even under the most demanding conditions. 

Requires "A" & "B" Looms. 

Need on board wideband, consider the Fury. 
Two e-throttles & onboard wideband, consider the Thunder. 
Direct Injection? You need Force GDI

Shipped locked and must be enabled before use. This increases security of shipping and provides information on when an ECU is first used for warranty purposes. Add "A" & "B" Loom if needed 

The G4+ Xtreme (black) offers the ultimate in engine management. 

There are many great new features with the (black box). Here are some to skite about 

A beautiful new robust metal enclosure 

Integrated mounting bracket that is invisible once mounted (easily unclipped with release holes) 

Eight peak and hold injection, user definable, 10 amp peak, 3 amp hold 

Mixture map, closed loop fuel correction. Automatic control via two O2 sensors 

OBDII compatibility 

Upgrades are now included 

E-throttle. Previously an upgrade for the red Xtreme e-throttle is now standard in the G4+ Xtreme black ECU. Use any e-throttle and pedal combination. Fully programmable e-throttle control complete with gear shift control and throttle blips 

Knock. Internal digital knock "windowing". Detects knock using factory or after market knock sensors 

Logging. Was 15 channels, now 100 channels of logging included 

CAN. Now user defined and supports two independent CAN modules 

Traction Control. Controlled tyre slip to improve vehicle safety, driveability and performance 


Eight saturated injection drives, eight ignition outputs, 11 analog volt inputs, 10 digital inputs, 10 auxiliary outputs * 

Four temperature inputs 

Two, thirty four pin, waterproof connectors 

External, 3, 4, 5 or 7 bar, MAP sensor (sold separately) 

CAN / RS232 port 

Software - PCLink 

Fast tuning with keyboard driven commands 

Six hundred pages of help on "right-click" 

Powerful logging analysis built into PCLink 

Tabbed, user configurable layout 

* Unused injection and ignition drives can be used as auxiliary outputs. 

Other WireIn ECUs: 





Four stroke, two stroke, and rotary engines supported 

Engines up to 12 cylinders supported 

Rotary engines up to 4 rotors supported 

All ECUs have on-board barometric compensation 


Three fuel equation modes: 

Traditional mode for quicker and simpler tuning setup 

Modelled mode, more complex, but delivers superior results 

Modelled - Multi Fuel, similar to Modelled mode but provides accurate fueling regardless of fuel blend. Often used for system running petrol-ethanol 

Support for group, sequential, group-staged, and sequential-staged injection configurations 

Accurate modelling and adjustment of fueling based on: 

Intake manifold pressure 

Throttle position 

Engine size 

Fuel pressure 

Fuel temperature 


Fuel density 

Current blended fuel stoichiometric ratio 

Fuel charge cooling 

Engine coolant temperature 

Intake air temperature 

Charge temperature estimation 

Injector flow rate 

Support for high impedance (saturated) and low impedance (peak and hold) injectors 

2D or 3D injector dead-time table with configurable axis 

Injector short pulse width adder table for areas of non-linear injector flow 

Advanced injector testing function that allows for control over total number of pulses, rate of pulses, and pulse length 

Four cold start stages based on engine speed, fuel blend, and engine coolant temperature. Auto adjusts cold start settings based on current fuel blend 

Optional 4D and 5D overlay tables with adjustable axis to allow more complex fueling arrangements to be setup 

Switchable dual fuel tables to allow different fueling for different situations 

Acceleration enrichment for when the engine is increasing in speed, with control based upon throttle position or intake manifold pressure 

Configurable overrun fuel cut function for reducing emissions, improving fuel economy, and reducing chance of backfires 

Close Loop Lambda compensation with lockouts for engine coolant temperature, throttle position, throttle position acceleration, start-up timer, and intake manifold pressure. Tuner is also able to configure the maximum trim the closed loop lambda is allowed to apply. Able to use two oxygen sensors to control closed loop lambda for banks on V and boxer engines. Capable of using narrow-band or wide-band oxygen sensors 

Individual cylinder fuel trims are able to be applied to the engine, with the trim being a constant fixed value, or each cylinder able to have a 3D table with configurable axis from which the trim is selected 

Set the injector timing anywhere within the engine cycle. Choose to use a single fixed value, or use a value selected from a 3D table with configurable axis. The injector timing can be configured to be the start, center, or end of the injection pulse 

Staged injection which is fully configurable including minimum pulsewidth lockout and activation engine speed. Injector dead-time table and short pulse width adder table configurable for staged injectors 

Auxiliary injection that can be used as a third stage of injection with each auxiliary injector able to have an individual 3D control table. Capable of being configured by duty cycle or millisecond units 


Support for seven types of ignition system: 


Twin distributors 

Wasted spark 

Direct spark 

Rotary engine - leading wasted spark 

Rotary engine - leading direct spark 

Odd fire wasted spark 

Set the spark edge to be falling or rising 

Millisecond and duty cycle ignition coil dwell modes. 2D or 3D dwell table with configurable axis from which the dwell value is selected 

Adjustable ignition delay compensation 

Configurable spark duration 

Maximum Advance setting to restrict the maximum amount of advance the ECU will apply if setup incorrectly. Used to help prevent engine damage occurring from over advanced ignition angle. Maximum angle is configurable by tuner
