G4X AtomX ECU

Description

AtomX

Small, but mighty!

The Link G4X AtomX ECU is the latest version of our entry-level ECU. Don’t let its size fool you however, the AtomX has expanded data logging and uses the same microcontroller as the entire G4X range! It is more responsive and has higher bandwidth than its G4+ Atom II predecessor.

G4X features 512 megabytes of logging at 32bit using up to 250 channels, each limited to up to 1kHz per channel (by the Operating System), with a maximum of 100 kSamples/sec.

G4X features 8 x faster communications speed, allowing you to download logs 8 x faster and pushes all the logging quickly up to a new and improved PCLink – available for download below in the features tab.

The AtomX can control up to 2 rotors or 4 cylinders with sequential injection and direct spark. Or, it can be used for up to eight cylinders using batch fire. Now featuring Knock Control.

This makes it ideal for naturally aspirated engines that just need a re-tune and don’t need all the extra sensors and features that come with our higher level ECUs.

Requires “A” loom.

The AtomX is ideal for:

1-12 Cylinder Distributed

2-8 Cylinder Wasted Spark

1-4 Cylinder Direct Spark

Odd Fire Engines

2-Stroke Engines

Configurable Firing Order

Configurable TDC Points (for odd fire)
