I just discovered my 2107 grandsport does not have the update, curious where most of the impact occurs, dealer told me it improves for track driving, I currently feel no difference between any of the settings suspension wise.
thanks

 

I found this: https://www.lsxmag.com/tech-stories/...-ride-upgrade/

Most reports around here focus on the improvements to the Tour and Sport modes.

You can't feel any differences in the modes now? There is a big difference between Tour and Track in terms of suspension firmness. Tour is almost Caddy smooth while Track will knock your teeth out on a rough road.

 

Since i have owned the car, bought used about 1 year ago, it has felt the same in all modes
I can say that tour and track feel pretty much identical to me,
It has been that way since i took ownership
Sounds like iIshould get it done

 

Then something is wrong... the difference should be noticeable even without the software update. Maybe you have really smooth roads, find a rougher road.

 

The mag ride update will make it ride smoother. Don't know if it will help track performance.
If you want to help track performance you need to get the DSC v4 ride control module. Pricey but works great.

 

I think my drive selector is disconnected
When I watch videos online, I notice that the dashboard view changes depending on what mode you select.
Mine stays constant no matter what mode i am in, i have read about a link between the DIC and the drive mode being possible deactivated
Not sure what that even means to be honest
Hoping this is just a setting or something

 

The owners manual is available online as a pdf at "mychevy" and will explain all that. In a nutshell, you can tie the display to the mode (and ergo mode selector) or you can keep the display (as well as the HUD and the exhaust) independent of the driving mode. Most people have a favorite display and exhaust setting, so they decouple those from the suspension mode. For instance a person might like the Tour display with the Track exhaust setting and the Sport drive mode.

At the bottom of the dash, in the center, you should see the letter change as you turn the mode selector. ie you'll see "T" for Tour, "S" for Sport, and "Tr" for track. I don't recall the eco mode off the top of my head but that's the 4th mode.

Bottom line....The car likely works as intended, whoever owned it before you decoupled the display from the drive mode, and you have some reading to do so you understand how it works.

 

Yes Link-To-Drive mode must be turned on to change the dash display. If not the settings are changing but the dash display stays the same which leads to confusion. It's normally pretty easy to tell between the settings as steering resistance and exhaust sounds change, but those too can be over riden which would make it SEEM like the controller is doing nothing.

 

I wonder if that is how many who are experiencing cracked wheels are driving, on public roads in track mode where the suspension is expecting something a little more refined than say a shitty public road with expansion slots and potholes? My Vette is going into the dealer next week for the TSB on the triple flush and I have asked them to perform the MRC update while they have it. I can only imagine that if the touring mode is made even more enjoyable, it should only help save the wheels.

Good point. My previous owner had a lot of little things adjusted that I have come to disagree with. In retrospect, I probably should have just reverted the settings back to default when I picked it up myself.

 

Many have suspected this and I'm sure the stiff track suspension setting doesn't help the situation. However not all tracks are smooth... for example I drive at Sebring which is known as one of the roughest tracks in the world. Almost all tracks have rumble stripes / alligator curbs and the fastest way around is often over these. So the wheels should be designed to take this kind of abuse.

I actually don't think Track is that bad - my previous car (a Nissan 350Z) in its stock form was somewhere between Sport and Track in terms of firmness. However its firm ride was one of the reasons I got rid of it... just too rough for daily use.

 

I have a 15 Z06/Z07 and I had the upgrade performed back in 2018. The first thing I noticed is it made the ride less harsh in Tour Mode. The update smoothed out the initial reaction to real sharp bumps. On track, I am not sure I noticed a huge difference in response. The update doesn't really soften the suspension it changes the suspension response.

If you don't see a change in the DIC when you turn the **** you have something wrong with the **** or the circuitry. When you turn the **** you should see the DIC change from Weather to Eco, to Tour, to Sport and Finally to Track. It doesn't matter whether you have the display slaved to the drive mode or not. The DIC will display all of those positions.

When you move the **** so the display goes from Tour to Sport you should feel a change in ride stiffness and when you go from Sport to Track you should feel another change to a much firmer ride along with very hard steering. When the DIC is displaying Track Mode you can push the center button twice and the DIC will then display WET. If you turn the **** again you will see DRY, SPORT1, SPORT2 and RACE be displayed as you move through the Track Sub Modes. To get out of the Sub Modes push the center button again.

If you don't see the DIC changing the way I described you have something wrong with the car that needs to be repaired. If you see the DIC changing the way I described and don't feel any difference in ride or steering effort you have something wrong with the car that needs repairing.

Link to Drive Mode means the instrument display is slaved to Drive Mode. In other words when the Drive Mode is in track position the display will show the Track Display which has a bar type tachometer and 3 lap time displays. Tour Mode gives you a digital speedo surrounded by a tach with important instrument readings in digital format displayed in a column to the right of the Tach. You can go into the display settings on the steering wheel to choose Link to Drive Mode or freeze the display in Tour, Sport or Track.
