Put your VIN in and click “Get Cal ID”.

Select “K19: Suspension Control Module” from the list. Click Next.

Select “Programming”. Click Next.

Select “With Semi Active Damping System” and click Next.

There will be two modules listed. “Operating System” and “Real Time Damping”. Click on “Real Time Damping”. If you see “New calibration to support performance parts and motor sport catalog customers”, the car has the update.

This is what mine said....Part NumberCVNBulletin #Description84316055N/A-SAD Calibration Update84136519N/A-Real Time Damping_________________________________ _

So, I guess this means my Magnetic Ride Control was not re-calibrated with the latest software, right?

tzoid9

That didn't "Paste and Copy" worth a crap....sorry about that!

Higgs Boson

I will have to look into this because mine does not say updated in the real time damping section although I have done it.....

cdh027

I did the update and mine doesn't say that?

CaddyRacer

my VIN shows this....I think it's NOT been done (I bought the car last month)​​​​​​​

cyi1

Something tells me this site isn't the most reliable lol

tzoid9

All negatives so far Cyi1....I am inclined to agree with you 100%.

I walked through the site just as you instructed and got exactly what you said one should see; Perfect!!! My car is a 2015 Z06/Z07.

Mine said..... so is mine updated ? i paid to have it done, but unsure if they actually did it :-(

snampro

Very helpful!

I was able to verify that I do not have the MR update, but I do have the 100 Octane tune!

Toddiesel

Definitely helpful. Worked perfectly for me. And since I felt ZERO difference after I had it done, I can go back and tell all the people that said the dealer probably didn't even do it that they are wrong. Thanks!

cyi1

I hope so or these dealerships are about to have a lot of angry customers and all the mag ride update threads are full of people that got a placebo pill

As far as I can tell this procedure only shows what is available to be flashed for your VIN, not what has been actually flashed or is current in your modules. When I flashed my own vehicle with the mag ride re-calibration I checked the site to see if it showed up after getting it authorized and it was there before I even programmed it.

I observed mine being done and there was a definite procedure with it to meet GM's requirements that the upgrade or download was installed properly. Two things that surprised me was that a portable AC converted to DC Power-Supply Unit was hooked up to the car during the whole time to maintain a prescribed level of voltage that would remain constant throughout the procedure and that the car was not to be started or moved for something like 12 hours afterwards while the system was establishing ambient temperature correction factors. My dealer placed the car in their first most upfront and observable stall at about 3 PM and the trained GM certified technician slowly and carefully walked through the procedure taking a good near 2 hours to be sure all was to his satisfaction.

We all left at around 8 PM and the car set overnight untouched until about 10 AM the next morning when they allowed me to start it for the first time. Up on starting the car there appeared to be a "hiccup" of some kind when the dash and infotainment screens opened - I caught my breath - and then it immediately did a "reboot" type of correction and all looked fine. All has worked fine since and I could tell a definite difference in the Tour Mode which is much less harsh. Also, a vibration that would periodically come and go that I had thought was maybe a wheel-balance problem or perhaps even to do with a transmission/torque-converter problem went away.

There is another procedure - I have done it in the past but can't recall how for now - where one can see an actual list of what is in their particular cars setup. It will show up there as "K19" Suspension something - sorry, I can't recall the actual descriptions wording; however, the "K19" numerical part will be there if the update was downloaded followed by the written verbal description. However, there is a question as to whether the install was done properly following GM's prescribed procedure exactly as I have read that some had it done and the dealer allowed them to drive their cars immediately afterwards and to take them home not complying with the 12 hour period to be allowed to set untouched and not driven.

You are 100% correct. If it doesn't show up here as an option, it's not available to be programmed.

NicD

Yes but my main point is that just because it's listed there on that site doesn't mean it's been flashed and that's the current calibration in that module, just that it's available to be flashed. I believe the only real way to know what is actually in the module is to use an MDI and the SPS software to try to flash the module and then it will tell you what the current calibration is which doesn't make it easy for anybody to check. Unknown if any of the aftermarket higher end scan tools can read out module software part numbers but pretty sure GDS can do it as well.

I paid to have my 2018 done. Process tool a couple of hours while the tech was on the phone with the TAC. He said they had to assign a code to VIN to allow it to be programmed.

According to this tool, it does not show that it has been done (if that is what this tool is telling us...)
