E+ Connect ECU Upgrade for AccuAir Systems

Bringing modern control to your existing setup doesn’t require starting from scratch. The AccuAir AA-3638 E+ Connect ECU Upgrade is designed to update pre-2019 SwitchSpeed and e-Level systems, giving you advanced features, improved reliability, and seamless wireless control.

With Bluetooth 5.0 connectivity, over-the-air updates, and app-based control, this ECU upgrade transforms older systems into a smarter, more responsive air management setup. Add in RGB backlighting and ride-height-on-start, and your suspension becomes both more functional and more refined.

Designed as a plug-and-play upgrade, installation is straightforward when paired with your existing AccuAir wiring and components.
