Recommendation
|
 "The team at Link has been working hard to continually improve their products and the results speak for themselves. The speed at which Link ECUs have evolved is truly impressive. Five years ago, Link only offered basic engine management systems that were aimed at the lower end of the market. In contrast, the current G4 systems are now highly respected throughout the world and are used in countless high-end motorsport applications. Despite the great success with their high-end systems, Link hasn't forgotten about their budget conscious customers either. As a clear demonstration of this, the new Link G4 Atom offers the power and flexibility of the G4 platform at an entry level price". "Although, the little Atom is limited by the number of inputs and outputs it has, if the application doesn't require these, then this ECU still delivers the flawless results that the G4s are known for".

We are confident that you will be delighted with this new ECU. The G4 Atom is in stock and we look forward to receiving your orders.
