I had to see what all the hype was about so I ordered up the Elevel kit with iLevel. My old Auotpilot v2 setup was 1/4" and the VU4 is 3/8" so I ran all new 3/8" lines while I ran the wires for the sensors. The installation was a chore, but you only have to do it once. I took my time on the sensors and made sure they were mounted safely, securely and cycle freely with a full range.
I didn't want an actual controller in the cab since I knew I wanted iLevel so I got the rocker switch version and left the switch bundled up in the trunk. Now that I'm using the system I think I'm going to run the rocker switch into the cab. The wifi isn't that great and sometimes unreliable. Sometimes it says my password is incorrect even though it hasn't changed. I must have got one of the older versions because it doesn't have the external antenna.
When I first fired the unit up my compressors did t kick on. After checking the relays and wiring I found the fuse had blown. Replaced it and both compressors fired up....and ran...and ran....and ran. Even with the ignition off. Comp1 output puts out a constant 12v+. I googled and found out how to swap to the secondary compressor output and that works like a charm. Still kinda disappointed that my unit is partially defective right out of the box(just like my Autopilot v2). Also, without a pressure gauge on the tank I had no way of knowing my tank was well over 200psi. Kinda risky...
Also, I wish the connectors were smaller or had some sort of disconnect so you don't have to make such a big hole to run a tiny wire through firewalls.
Enough with the complaints. I'm impressed with the system. It's fast, accurate, smart, and RELIABLE. I love knowing that when I hit a preset, it's going to be EXACTLY where I programmed it to be. I can actually get an alignment now since I have an accurate, predictable ride height to drive at. It's expensive, but it's worth it.
