Overview

As Link's entry-level ECU, the AtomX delivers proven performance in a compact and capable package with exceptional value.

Sharing the same championship-winning G4X architecture as the rest of the G4X range, the AtomX delivers the same proven tuning experience and reliability trusted by enthusiasts and professional tuners worldwide.

The AtomX shares the same processor, firmware, software and standard G4X feature set found throughout the G4X range. Features include CAN Bus, Flex Fuel, Flexible Engine Protection Limiters, CAN Keypad Control, Open Loop Boost Control, a built-in Trigger Oscilloscope, OBDII output stream, continuous barometric correction, compatibility with aftermarket displays and 512MB of onboard data logging.

Designed for builds that do not require expanded I/O or advanced motorsport features, the AtomX provides all the essentials needed for reliable, high-performance engine management. It supports a wide range of tuning strategies, including VE and traditional fuel modelling, individual cylinder corrections, dual fuel and ignition maps, boost control and advanced engine protection strategies.

The AtomX is the ideal solution for builds requiring proven engine management performance and core G4X functionality in a compact and cost-effective package.

The table is going to need the following footnotes somewhere, preferably at the bottom:
‡ G5 Voodoo Pro has 12 inj, 8 ign, plus 4 multipurpose (inj, ing, aux) drives (24 total). † Check Specific pinout for number of I/Os exposed.
† Check Specific pinout for number of I/Os exposed.
# 4 pins are multi-purpose Aux or Digital Input pins. Each pin can be either Aux or Digital Input, not both at the same time.
* 2 Digital Inputs required when using 2nd CAN Bus.
§ 4 pins are multi-purpose Injection, Aux or Digital Input pins. Each pin can be either Injection, Aux. or Digital Input, not all at the same time.
Link ECU products should not be used where they interfere with a vehicle’s safety or emission control features. (no footnote symbol on this one).
