ePlus by AccuAir CONVENIENCE & CONTROL The ePlus app for your AccuAir e-LEVEL+ Air Management System provides convenience and control directly from your phone. While the ePlus app works in partnership with the hand-held remote, it also works independently, allowing you the freedom from having a secondary control source on-hand. Adjust ride height from inside or outside the car, thanks to Bluetooth® 5.0 connectivity. Plus, it’s on your phone, so it’s with you wherever you go. In a word, the ePlus app is CONVENIENT. The ePlus app gives you even greater control over existing air management system functions, as well as app-only features like, Valet Mode, System Diagnostics, and Service Routines, to name a few. System functions aside, ePlus provides three screen modes so you can choose the interface that’s right for you and your driving needs. In addition, ePlus is cross-functional with AccuAir systems that either run with or without height sensors. You want CONTROL? You’ve got it with ePlus. Have questions, concerns, or simply want more info? Contact us at support@AccuAirSystems.com or 877-247-3696. www.AccuAirSystems.com ePlus App Features: Real-Time Height Streaming Provides a live display of the percentage of suspension travel for each individual corner, along with the target height when in a preset position. This not only allows you to see exactly what your car is doing, but also provides a visual indication of RideMonitor at work. Over-the-Air Updates The ePlus app has the ability to provide over the air updates to both the e+ Connect and the Touchpad+. This capability allows AccuAir to add new features and updates to improve system performance. For example, the initial update includes patches to resolve memory corruption bugs that prevent users from saving new heights and settings. Valet Mode Setting With our new Valet Mode you now have the ability to limit the system functionality to only using position 2 and 3, with RideMonitor and Ride Height on Start forced on. This setting can only be switched on and off from the e+ mobile application. No Height Sensor Mode For those customers not running height sensors they can now turn on No Height Sensor Mode to replicate classic SwitchSpeed functionality. This setting will eliminate the height sensor error indicators on the Touchpad and default to the Manual screen on app launch. The ePlus mobile application uses a fixed time pulse for button holds to allow for a consistent pulse length when airing up. Recalibration “LITE” The Recalibration “LITE” procedure allows users to put the system back through a calibration process to improve accuracy, when making damper adjustments, or when switching pressure ranges without having to resave heights. Service Routines A new feature with the ePlus mobile application are the first two service routines to be integrated into the system, Service Mode and Compressor Force On. Service Mode disables the system entirely to allow for vehicle maintenance with ignition on while not having the air management system active. Compressor Force On will allow the user to manually turn on the compressor outputs, bypassing the pressure sensor to help in troubleshooting compressor wiring challenges. System Diagnostic To help with setting up height sensors and troubleshooting, this screen provides a live view of the system voltages (pressure sensor, height sensors, battery) while allowing manual adjustments. In addition, the system will display calibration status, the number of corners in use, as well as the state of the ignition and E-brake inputs. ECU Backlighting With the new e+ Connect featuring full RGB lighting you now have the ability to set any custom color and brightness level from your mobile device. Additionally, you can enable or disable lighting to suit your preference.
