With Link ECU, you get a state-of-the-art ECU at a great price, backed by the reliability and support of a market leader.
Some of the most reliable and robust ECUs on the market.
Backed by Link's limited lifetime warranty.

Small but powerful!  The Link G4X AtomX is the latest version of our entry-level ECU.

Do not let its size fool you: theAtomX
uses the same microcontroller as the entire G4X range. AtomX can control up to 2 rotors or 4 cylinders
with sequential injection. Alternatively, it can control
up to 8 cylinders with wasted spark.
Now includes knock control.

General details:

° Sensor MAP external (Not included) (The original sensor can be used on most models)
º Built-in fault detection, software diagnostics and DTC fault codes, like an OEM ECU, for quick troubleshooting.
º Correction: INTERNAL REAL-TIME BAROMETRIC COMPENSATION
º Communication: CAN-BUS SEAMLESS (VW, AUDI, 350Z, SUBARU, MINI R53–R56, OPEL CORSA/ASTRA, PORSCHE 987–997) / CAN immobilizer support
º Direct flex-fuel sensor input without external modules.
º Controls 4-stroke, 2-stroke and odd-fire engines.
º Configurable firing order and TDC for odd-fire engines.
° Mapping: SPEED DENSITY (volumetric efficiency (VE) model) or Alpha-N (TPS).
° Controls 1–12 cylinders with a distributor, up to 8 cylinders with wasted spark or 4 cylinders fully sequentially.
° Boost control with PRECISE DUTY CYCLE (3 TABLES, 3 DIFFERENT BOOST LEVELS)(Open loop with voltage compensation and air temperature, coolant temperature and gear corrections)
° USB communication and latest-generation G5 software. SOFTWARE LINK
° Electrical protection on all inputs and outputs.

INPUTS:

* 2 x Digital inputs (Hall speed sensors, pushbuttons, switches and triggers)
* 2 x Temperature input (coolant or air temperature)
* 3 x Analog inputs for pressure, position, etc. (e.g. TPS, oil and fuel pressure)
* 2 x Trigger inputs (2 engine position sensors: 1 CKP and 1 CMP)
* 1 x Knock input (dedicated knock sensor input)

Analog input details:

• Each channel is independently configurable using software presets or custom tables.
• Wideband O2 input (through an external controller, e.g. AEM 30-0300)
  
• Throttle position signal (TPS)
• Pressure signal (external MAP, BAP, fuel, oil)
• Built-in barometric pressure sensor 
• Airflow sensors 
• Temperature (coolant, air, general purpose)
• Gear detection through analog input, CAN, or calculated RPM / speed

Digital inputs

• • Each channel can be independently configured with pull-up resistors (SWITCHABLE INTERNAL PULL-UPS) .
  • All digital inputs can read signals up to 10 kHz.
  • Duty cycle measurement on all inputs
  • Turbo speed
  • Ethanol sensor (FLEX-FUEL)
  • Wheel speed detection 
  • Anti-theft (immobilizer) control through digital input, CAN communication, or both.

OUTPUTS:

* 4 x High-impedance injector outputs (resistance above 7 ohms)
* 4 x Outputs for coils with built-in igniters or external ignition modules.
* 4 x Auxiliary outputs (unused ignition and injector outputs can serve as auxiliary outputs, E.G.: A 4-cylinder engine WITHOUT CMP using wasted spark and semi-sequential injection uses only 2 coil and 2 injector outputs; the remaining outputs can perform auxiliary functions)
*Output of +5V for sensors (TPS, pressure, etc.)

AUXILIARY OUTPUT APPLICATIONS:

• Each output can be configured separately
• Unused ignition and injector outputs can serve as auxiliary outputs
• General-purpose low-side or PWM outputs
  
• Fuel pump ON/OFF control (up to 3 pumps activated at different RPM and injector duty points) or duty control (closed loop with injector duty compensation)
  *** Supports calculated channels for methanol pump activation maps ***
