Link G4X AtomX ECU

Small, but mighty!  The Link AtomX can control up to 2 rotors or 4 cylinders with sequential injection and direct spark.  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 higher-level Link ECUs. 

The AtomX has expanded data logging and uses the same microcontroller as the entire G4X range. The processing unit 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 than G4+ ECUs, 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 is an automotive control unit. 

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) 

Important:  Due to the limited number on inputs/outputs on this ECU, Some outputs (ie: VTEC) require a relay and/or other considerations which are not present on the factory wiring.

• Product failure due to a manufacturing or assembly problem.
• Outside company products. We will handle the hassle of shipping your product back to the manufacturer for warranty processing. Let us replace your product for you and we will deal with the warranty process with the manufacturer later.

What is NOT covered under warranty:

• ECU failure due to improper vehicle wiring (ie: ECU component fries due to sensors being connected incorrectly, low resistance fuel injectors being used without a resistor box, ROM chip being installed backwards by user, customer attempts to modify ECU in ANY way other than intended, etc.)
• Product being used in a way other than the intended use.
• Rear "warranty void if removed" sticker on ECU has been removed or altered.
• Failed, shorted, or corroded ECU board due to water damage.
• Any and all outside labor charges associated with removing and replacing product or diagnosing product failure.
• Wire harness failure due to improper use or rough handling.
• Cosmetic variances from manufacturing (ie: ECU lid has variation in powder coat texture or color within acceptable limits, wire harness color variations within acceptable limits).

How the warranty process works:

If you've determined that a product has failed due to a manufacturing defect, please contact us via email at sales@hamotorsports.com to review the symptoms you are experiencing to allow us to assist you with troubleshooting before shipping your product back to us for warranty. Many times, we can help you with the problem and determine what is being done incorrectly or how to configure the product properly to restore correct operation. If after we discuss the issues you are experiencing we determine that your product may need warranty replacement or inspection we will instruct you how to return it to us. Please note that we test EVERY ECU, EVERY ECU package, and wire harness components on our state-of-the-art testing equipment for complete proper operation before packaging and shipping to customers. PLEASE verify ALL wiring, installation, software settings, etc. are correct BEFORE contacting us for warranty repair/replacement.
