Why do I want a height and pressure-based control system instead of pressure based?
Pressure based systems are just that, they go to a preset pressure where possible. The ground you park on will never be 100% level all the time and this is a major factor. Another major factor is the type of bags. Sleeve bags by design roll over themselves at the lowered height, and sometimes the upper piston, the shape and length of this piston, can mean the air volume changes but the pressure stays within a few psi. Our own testing has shown this.
On larger sleeve bags used on lifted trucks, and 4-6” sleeve bags in cars up to 2” of travel before noticeable pressure changes. So, we only recommend a pressure-based system for double and or triple convoluted bags. Our pressure sensors are very accurate and have no effect in this described scenario.
- Using our Height and Pressure.
- The priorities become the position of the travel.
- The pressure is used to keep the spring rates correct.
- And to detect cross jacking, sometimes referred to as wedge.
We have our own code embedded in our ecu called “Terrain Sensing”.
Using our height and pressure we can detect when the car is on uneven ground and prevent it making any adjustments, A popup will come on the screen telling you its sensing terrain, it will auto check again after 10 seconds if you don’t acknowledge this warning, so you don’t have to have the screen on for this to be operational.
Level Ride has a shoot to height accuracy settings of 3% 5% and 8% where other systems work off 8% 12% and 15%
Level Ride doesn’t have these percentages as final setting and will continue to trim the height over the first 5-10 mins of driving and get you back within 1%, as it is looking at an average every minute so you’re not constantly adjusting. If you are driving off road or driving aggressively a lot, this system will ignore peaks and troughs outside the accuracy setting as not being part of your average height meaning it will make far less adjustments.
Level Ride can detect acceleration and cornering so knows it’s not part of the average.
Level Ride also has Brake detection for the 12v signal. This function tells the ECU not to make adjustments, (unless one has already started), and won’t make adjustments while sitting in traffic when on the brake. Level Ride caters for Load changes too
