Check this out!!! (ECS control module)

[Gtecko]

that is what I thought UtraCow... so I am glad to read that the settings are being kept in. It would defeat the purpose of the Mando if you had to reconnect every single cycle

 

[D.J.]

Sorry, but I had o contradict you in this case...
I own one of the first ECS10. It´s powered by a IGN-Fuse and the Mando-settings (once stored by the app) always override the stock-settings. For month. As long as the ECS10 is shut off by App or IGN-power off...

...maybe a problem of power-sequence?

What method did you use to test this?

 

[D.J.]

I can confirm this. Mine is installed on a switched power source as well. The only time reconnecting from the app to the unit is needed is if you want to change the setting.

Also, from my research and personal R&D, ride *does* control bump damping while handling affects rebound damping. It can take a bit of reading and experimenting before you start to get an idea of what and how each of the settings changes things.
I was going to post a link to a good suspension tuning and dynamics guide that continues to be useful in my development, but apparently I’m still not allowed to post links even though I’ve been registered for quite a while now. The hazards of being an infrequent poster I suppose.

One additional thing I’ve observed - whatever you set within the ECS10 serves as a static, base calibration where the two different suspension modes act as behavior modifiers on top of that; likely within their own set ranges. Not everyone may notice the difference, depending on road surface, but it is distinct and repeatable.

Did you measure the voltages at the shocks?

My data tells me the behaviour modifiers you are speaking of, do not work at all.

The Mando setting over-rides whatever setting you make on the drive mode dial.

Good news.... New version of the app to test...

Claims to auto connect.! Will test today

 

[D.J.]

V1.06

 

[D.J.]

Here is a short video of the auto connect feature working with one single tap, all you have to do is open the app, and the rest is automatic, in the newest version 1.06 beta

I don't see 'Auto Connect' making much difference for convenience, as you still need to have your phone with you, have it link to the car, and open the app. As there seems to be some difference of opinion over whether the car retains the settings from the previous driving session, it should be relatively easy to test without checking system voltages.

Set the shocks to 100 percent hard in the Mando app, which (having had my factory shock settings default/fail to this once following a full battery discharge) is very easy to identify - the car rides like an unladen 5 ton truck, which is a stiffness setting that cannot be achieved with the factory systems alone.

Then shut the car off, remove the phone from the area to be certain the BT link is broken, and see what happens the next time you start it up - should be pretty evident whether it retained the Mando setting or not.

I don't see this version being available for iphone. I do see 1.03. I am on 1.02. Does anyone know if this version enables autoconnect on iphone?

Spot on! I always thought the settings were kept whether the app was connected or not. Your suggestion will tell the truth fairly quickly.

Yup

If you see post #427 - that's exactly what I did

I have tested this with both constant power and switched power to the MANDO ECS10 box

What method are you using to obtain data if you don’t mind me asking? The only way to properly measure the control voltages at the shocks when in-use would be a diagnostic and programming tablet, something like Ty Davis has been using.

From quite a bit of observation, I’ve found a good deal of difference during dynamic response situations (cornering) in what the car does, using my normal daily Mando calibration. There is a difference with straight-line as well, but it’s more subtle. It’s not a night/day difference for sure, but try driving on a road with constant irregular bumps - first with the OEM suspension setting on Sport and then Custom (with everything Sport except for suspension set to Comfort); making sure to leave your Mando setting the same for both. This is the best example I can think of to feel the difference.

That said, my current calibration is somewhat under-damped on the bump side, so a lot of the surface feel comes through (to both good and bad effect). It’s entirely possible that on other calibrations the difference may be very difficult to notice.

You can probe the wires directly at the OEM ECS (located rear drivers side luggage area)
Sorry for the bad quality pics of a screen

Next time I'm in there I will post pics with voltages etc..

I don't see this version being available for iphone. I do see 1.03. I am on 1.02. Does anyone know if this version enables autoconnect on iphone?

V1.06 is the first version that enabled the auto connect feature - released as a beta build on March 4th 2020

I can't speak to any iOS BETA versions - not sure if that is available.
1.03 is the current stable non beta release for both Android and iOS.

The electronic shocks on our cars do not possess the ability to adjust rebound damping. Only compression damping adjustment is possible.

There is only 1 solonoid valve per shock, and only 2 wires going from the ECS unit(OEM) to each shock solonoid (as seen in the attached schematic)

This allows for adjustment of compression damping only.
It is "possible" that the solonoid valve controls both the compression and rebound together, but then we would not have independent control over compression and rebound.

I know these images are poor quality. But hopefully you can read what I am describing in the OEM schematics attached.

Well today the update for IOS came out and it auto connects. I am going to enjoy this more now that I know I have been missing the improved Mando setting due to thinking that the settings were persistent through restarts.

What is the new iOS version #?

Are those wiring diagrams from KGIS? Those are the first (OEM?) documented evidence I've seen that back up what some have thought regarding the Stinger's ECS system reacting to G-sensors EDIT: (although I believe it was Ty that first confirmed the constant solenoid adjustment nature). Good find!

Not completely sure what to tell you about the compression and rebound adjustment. There are several possibilities for how the system was implemented, but changes to each of the types of adjustment absolutely do change compression and rebound, or something mimicking them. The combined adjustment theory is decently likely, as it's a common cost compromise between 1-way only and 2-way dampers.
All I'm trying to relate is the changes that each can make map directly to how those parameters translate into objective ride and handling results and line-up with everything I've been able to find regarding suspension tuning and mechanics thus far.

1.03. I love it that all I have to do is open the app and click the setting. Before it was open app, pick car, go into settings, go into connecting to ECS, push scan, click on the detected module and then set the preferred setting. Much easier now after the update.

Also very glad to have the confusion cleared up on whether settings are persistent. I was starting to come to the conclusion that the unit was not that big of an improvement. I was only going in and changing settings once a week or so when I was in a mood to go into a sport setting. Otherwise I am on comfort most of the time. So the vast majority of the time I was just driving around in the stock comfort mode. The past couple of days I have been setting comfort each time I get in and the ride on the Mando is noticeably smoother than the stock setting. It is much more convenient having one click setting after just opening the app. I appreciate the info clearing this up.

Ty Davis posted info several months ago regarding this. He was reporting that his scanning tool was showing voltage changes while driving. Probably changing damping when acceleration, cornering and braking were detected.
