EXPERT SUSPENSION SINCE 2017

INCLUDED TECHNICAL SUPPORT

What is Pressure+?

The Pressure+ Upgrade is an alternative to the Height+ system (height sensors) for controlling your AccuAir air ride. Instead of measuring the physical position of the suspension, it uses 4 pressure sensors — one per air spring — to control and memorize heights using pressure values. Everything is controlled from the e-Level+ smartphone app by activating Pressure+ mode in the advanced settings. Simpler to install, with fewer exposed mechanical components, and directly plug & play with your e+ ECU.

📊

Individual pressure

Real-time display of the pressure in each air spring, corner by corner, from the app.

🔌

Plug & Play

100% plug & play harness for direct connection to the AccuAir e+ ECU, with no modifications.

📱

e-Level+ App

Calibration, presets, and monitoring from the AccuAir app on your smartphone.

🎯

3 programmable heights

Lowered, driving, raised + fully lowered. Precise memorization of each position via pressure.

🚀

Ride-Height-On-Start

The vehicle automatically raises to your driving height as soon as it starts.

⚡

Straight-To-Height

Direct adjustment without valve “pulsing” — you reach the correct height immediately.

Pressure+ vs Height+ — which one should you choose?

Both systems let you memorize and reproduce heights accurately. Here are the key differences to help you choose based on your setup and budget:

⚡ Pressure+ (this product)

Simpler installation — no sensors to mount on each wheel
Fewer moving parts that could break
Significantly lower price than the Height+ kit
Same Straight-To-Target adjustment style as Height+
Less accurate than Height+ for reaching an exact height
Does not automatically compensate for load variations

📡 Height+ (height sensors)

Most accurate method for reproducing an exact height
Automatic compensation for load variations (passengers, luggage)
More complex installation — a sensor must be mechanically mounted on each wheel
More exposed mechanical parts (link rods, connecting arms)
Higher price than the Pressure+ kit

💡

Our recommendation: If you want a simple installation and do not need millimeter-perfect precision (show car, stance, urban driving), Pressure+ is the ideal choice. If you often drive with a heavy load (family, long journeys) or want perfect height repeatability, choose Height+.

System compatibility

AccuAir VU4

Compatible via ¼ NPT → ⅛ NPT reducers (not included). Connects to the manifold's pressure ports.

ENDO-VT

Integration via an inline pressure tee between the valve and the air spring. Easy to install.

Other manifolds

Compatible with any AccuAir manifold by placing the sensors inline between the valve and the air springs.

e+ ECU

Requires the AccuAir e+ ECU. Activation in the advanced settings of the e-Level+ app.

⚠️

Essential prerequisite: This kit requires the AccuAir e+ ECU to operate. It is not compatible with Air Lift Performance, Airmext, or TA-Technix systems. The wireless device (smartphone/tablet) is not included in this kit. Pressure calibration is required during initial installation.

Package contents

🔌

1 × wiring harness
Plug & play — direct connection to the AccuAir e+ ECU
📊

4 × pressure sensors
One per air spring — individual measurement of each corner

📌

Not included in this kit: Inline tees for the VU4 manifold, NPT reducers, and the AccuAir e+ ECU. If you use a VU4 manifold, order 4 inline tees separately to simplify installation.

Frequently asked questions

I already have an AccuAir system with height sensors (Height+). Can I switch to Pressure+?

Yes, Pressure+ is designed to replace or upgrade an existing system. If you have a VU4 manifold, order 4 inline tees separately to make installing the pressure sensors easier. Recalibration through the e-Level+ app will be required after the swap.

Is Pressure+ as accurate as Height+ for reproducing ride height?

Pressure+ is highly accurate under a constant load, but unlike Height+, it does not automatically compensate for load variations (passengers, loaded trunk). If the vehicle’s weight varies frequently, Height+ will remain more reliable for perfectly repeatable ride height. For a show car or static-minded setup, Pressure+ is more than sufficient.

Do I need a smartphone to use this kit?

Yes. Pressure+ is configured and calibrated through the e-Level+ app (iOS and Android). The smartphone or tablet is not included. You can also use the AccuAir Touchpad+ if you have one—it is compatible with this system.

Is this kit compatible with my ENDO-VT manifold?

Yes, absolutely. On the ENDO-VT, simply place the inline pressure sensors between the valve outlet and the air spring. It’s a straightforward installation that requires no drilling or manifold modifications.

Is this kit difficult to install compared with height sensors?

No—this is actually one of its main advantages. There’s no need to install mechanical sensors on every wheel, adjust linkages, or check alignment. Simply connect the harness to the e+ ECU and install the 4 inline pressure sensors in your air lines. The longest part is calibrating through the app, which generally takes less than 20 minutes.

Still unsure about your AccuAir upgrade?

We'll help you choose between Pressure+ and Height+ based on your setup, budget, and intended use. Get your answer in just a few minutes.
