e-Level ECU

e-Level+ is the highly anticipated next generation air suspension controller from AccuAir built on the longest running foundation of technology in the industry. This new generation control system is Bluetooth 5.0 enabled and provides a simpler user experience, with even better performance and reliability, while answering the requests of customers from every corner of the globe. Whether you choose to start simple with the upgradable e+ Connect wireless switchbox, or opt to start with the best by adding height sensors and the next level Touchpad+, you will be guaranteed to find the features and value that meet your needs. As always, you can count on the most accurate air suspension controller in the world from AccuAir and you'll drive comfortably and consistently knowing that the core of every e-Level+ system has been proven on more than 40,000 vehicles over 10 years.


Since its release, the e-Level™ Controller has become the industry favorite for accuracy, reliability, and ease-of-use. It offers the ability to save three unique heights into memory at the touch of a button using TruPosition™ height sensors installed in each corner of your suspension. The key to this technology is its RideMonitor™ Mode; while parked or driving, the system will maintain the vehicle height when loading or unloading passengers or when road conditions change. All of this automatic intelligence is unnoticed by the driver, providing improved ride quality and handling characteristics for any vehicle with Air Suspension. Each system calibrates to the vehicle upon installation and then learns how your Air Suspension behaves over time. This flexibility allows the e-Level™Controller to be used on ANY vehicle and requires NO user tuning.
