Link G4X AtomX ECU

The most recent iteration of our entry-level ECU is the Link G4X AtomX ECU, it certainly packs a punch!

Don't be fooled by the Link G4X AtomX ECU, although diminutive size, though; it uses the same microcontroller as the full G4X line and has enhanced data logging! Compared to its G4+ Atom II predecessor, it is faster and has more bandwidth. Check the video out here!

G4X offers 512 MB of 32-bit logging with up to 250 channels and a maximum sampling rate of 100 kSamples/sec. Each channel is limited to 1 kHz by the operating system.

You can download logs from the G4X AtomX ECU 8 times faster thanks to its 8x faster communications speed, and it pushes all the logging swiftly up to a new and upgraded PCLink.

A new and updated PCLink, which is available for download below in the features area, receives all logging swiftly thanks to G4X's 8x quicker communications performance, allowing you to download logs 8x faster.

The AtomX uses sequential injection and direct spark to manage up to two rotors or four cylinders. Alternately, batch fire can be used for up to eight cylinders. Knock Control is now available.

Because of this, it's perfect for naturally aspirated engines that only require a tune-up and don't require all the additional sensors and functions found in our higher level ECUs. (needs a "A" loom)

The Link G4X AtomX ECU 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)
