The Tesla ECM puts out a 1Khz 16 v signal as measured by oscilloscope. I am curious to know how you confirmed that the dampers are fully soft with 0 current.

I’ve started a petition to show Tesla the breadth of this issue. If you’ve got a problem with your suspension, sign it! The petition will go to Tesla executives. Also, send a link to the petition to everyone you know who owns a Model S or X. Be a part of the effort to get this problem...

If you have a refreshed Model S or X, you didn’t get the variable suspension you paid for. Be a part of the solution to this problem by signing this petition! Also, be sure to send a link to everyone you know who has one. With your help we can get this fixed! https://chng.it/qwDp6brYYp

I really don’t know what the Tesla system is capable of, but the problem is that they haven’t even tried yet! NONE of the physical settings they are using open the valves enough to soften the ride. Please see the thread “Physical measurements of variable suspension show that you’re NOT getting...

The recording oscilloscope is a good idea! Do you have such an instrument? If so, it would be great if you could take the readings. I suppose one could also just video the scope while driving the same route in each ride mode. I would sure welcome the input. I won’t be able to do much more...

This has been done. Read sub-thread 6 of this thread. They found that their cars were identical. The most current thinking on this subject is found in the thread “Physical measurements of variable ride control show that you’re NOT getting the ride you call for “. Everyone should move over to...

I’m retired (that’s how I can waste all this time on this issue!). I did coding/systems analysis… mostly for the manufacturing industry. I am an electronic hobbyist and have always worked on/restored cars non-professionally. (When I got my first car I immediately disassembled it).

Thanks for the thoughtful comments! Your concerns are valid. I think I did address most of them in the video though. The problem is that I was trying to minimize the length of the video so a lot of information comes at you pretty fast. (You almost have to watch it twice to catch everything!)...

It turns out that “Sport“ is the only Variable Suspension mode that actually delivers what you call for. All other ride modes are virtually the same, forcing the shocks to their stiffest possible setting. Watch this video to see physical measurements of the actual shock settings that result...

If you have a refreshed Model S or X, your Variable Suspension feature is NOT working as advertised. Watch this short video to find out what’s wrong and what to do about it.

Hi guys! Sorry… I’ve been a little distracted for the last few months. But, in that time, I’ve refined my thinking and produced a new video detailing the problem. First, I have to comment on Doug’s feeling that only early MS refresh cars are affected. This is a SOFTWARE issue. Early cars...

When you get together, please try the old “shade tree mechanic’s” shock test: one of you sit in the car and activate the suspension, while the other simply bounces the fender up and down. This should give you a good “feel” for the damping rate. A low damping % will be noticeably easier to push...
