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. 

The Link G4X AtomX ECU may be our entry-level ECU but don't let its size fool you. 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)

Whoa - 2020 Suburban
Size: 9005+H11
Finally decided to replace the halogens on my 2020 Suburban, and the difference is literally night and day. I do a lot of early morning driving and suffered for 4 years with the halogens. If this is you, stop suffering and upgrade your lights. You will be glad you did. The market is flooded with these LED upgrades, I used AI to help me determine the right fit, best value for the money, and most importantly something really bright. It returned a few options and this was one of them. I can’t speak to the longevity or durability yet, but the results are amazing. The fit is direct replacements, and they look great. Installation was straightforward but did take about 30 mins or so. Basic tools needed for the suburban, 10mm socket, flathead screwdriver, and a panel pry tool was helpful.

Fit 2015 228xi even tho not exact shape as oem
The large clip that has the feet that point out in second position(ballet term, google it so you see what the orientation looks like) fits with much more ease than you’ll think. It won’t hook into its oem place but the top flat squared off part will hook to the interior roof of the that general area snuggly. Spent 1.5 hours trying to bend the smaller ones into a similar shape to oem and then it hit me. The bigger one would probably be large enough to catch the top of the bulb housing. Learn from me. Try the big one.
