🔧 What is the AccuAir e-Level+ ECU Upgrade AA-3638?

Do you already have an AccuAir system — SwitchSpeed or e-Level before 2019 — and want to give it a second life? The AA-3638 is made for you. This new e-Level+ ECU simply replaces your old control unit, giving you all the features of the latest AccuAir generation without having to buy everything again.

Result: long-range Bluetooth 5.0, wireless control via the e-Level+ app on iOS and Android, automatic over-the-air updates, customizable RGB backlighting, and automatic lift on startup. Your existing installation stays in place — only the ECU is replaced.

Important: This product is the ECU only. It does not include a wiring harness or pressure sensor. If your existing harness is compatible, no additional purchase is required for basic installation.
