[ANSWERED] Magnetic Ride Performance Calibrations
The original question is here.
Car54 asked:
The recent announcement about the availability of improvements in the suspension calibrations for the C7 said this:
"2014-16 Stingray with Z51 features new calibrations in Tour and Sport modes.
2016 Stingray (non-Z51) features new calibrations in Tour, Sport and Track modes.
2015-16 Z06 (non-Z07) features new calibrations in Tour, Sport and Track modes.
2015-16 Z06 with Z07 Performance Package features new calibrations in Tour, Sport and Track modes."
Why was the 2014-2016 Z51 not included in the Track mode updates? The 2017 cars including the GS were not mentioned nor was there a mention about the 2018 cars. Do the 2017-2018 cars including the GS already have the enhanced calibrations or will they be a part of a future update.

Tadge answered:
One good thing about this Ask Tadge feature on the Forum is that you don’t just get access to me, but to the whole Corvette team as well as supporting organizations like GM Performance Accessories. Many of you are familiar with Jim Mero, our ride and handling development engineer who developed the calibration upgrade packages being offered through GM Performance Accessories. I asked him to clarify the whole picture in his own words. And here he is:
Before I get into the rollout of the calibration, and the questions asked, some history might be in order in an effort to make a very complicated situation clearer.
I have read through almost all the threads on the Corvette Forum about the MRC aftermarket calibrations. Overwhelming is an understatement. This is a complex situation and deserves a proper answer, which isn’t short.
With Magnetorheological (Magnetic Ride Control/MagneRide/MRC), we continue to learn and improve as we develop our higher performance variants. Over the past year and a half new tools have been created to help us better analyze data recorded on the bench, on the road, and on the track. Utilization of this data analysis was significant during my tuning of the ZR1. While tuning the ZR1 I realized a revolutionary change that not only improved track performance but also ride quality and handling in Tour and Sport. A change so significant I felt obligated to not only roll it into future model years for all MRC Corvettes, but also make it available to all customers already in possession of a 7th generation Corvette with MRC. While I wish we could roll these out immediately for all, it takes a significant amount of work and time to execute each calibration. Tour, Sport, and Track for each Corvette MRC chassis package have their own individual calibrations. None are shared between any 2 variants. All must go the same extensive validation process as a production implementation. All will be part of the 2019 production fitment. Including the ZR1 I revised 21 total new calibrations by September, 2017. The cadence and roll out of the new MRC calibrations for Chevrolet Performance were determined in the order they were completed.
I will try to address/clarify the questions from the “Ask Tadge” post as well as the ones I am already anticipating based on this reply, including the ones that I recently read in forum posts.
Why is there no track calibration offered for Z51?
Confusion about the cost to the customer.
Confusion about dealer knowledge about the calibrations.
Now I will attempt to go through each MRC package and give a short explanation of the benefits included in the Chevrolet Performance offerings. Again, each chassis package and mode has its own individual calibrations. None are shared between any of them.

Upon the completion of the track calibrations I rotated several of our track development engineers with different driving styles through the cars. The result is what the best balance is based on each driving style. If more understeer is desired, this can be easily accomplished by purchasing and installing
If even more precision is desired, Chevrolet Performance also offers lower control arms with stiffer bushing.
Well, that’s a long explanation, but it’s a complicated situation which is why we assume the question was over overwhelmingly voted for and asked in the “Ask Tadge” forum.

I will try to address/clarify the questions from the “Ask Tadge” post as well as the ones I am already anticipating based on this reply, including the ones that I recently read in forum posts.
Why is there no track calibration offered for Z51?
- As I stated above, I needed to release 21 calibrations for the 2019 production fitment which include the Chevrolet Performance upgrades. Time allotment was not conducive for the implementation of a Z51 track calibration. A new Z51 track calibration is on my “things to do” list, but my “task at hand” list is much longer.
- If you’re wondering how could the base car plus F55 (MRC) include a new track calibration but not the Z51, the answer is; like the base car, the base + F55 was never intended to be a track car. So the calibration in track mode is really a hybrid between Sport and Track, something like a Super Sport.
- Model year 2017 MRC vehicles were the same as 2016 with the exception of the Grand Sports which did reflect a partial representation of the revised tuning philosophy.
- Also included for 2017 production was a new Track calibration for Z06/Z07 (minus the temperature compensation as discussed below).
- As I stated above, all 21 2019 production including Chevrolet performance calibrations were completed in September, 2017. This was approximately 8 months after the 2018 calibrations were released for production.
- When we hit our 2018 production release dates, the progress I made thus far was released for 2018 production in Tour and Sport for: Z51, Grand Sport Base, Grand Sport w/Z07, Z06 Base, and Z06/Z07.
- So yes, Chevrolet Performance will be offering new calibrations for all 2017 and 2018 MRC equipped vehicles including Grand Sport, expect to see the remaining models released in Q1 2018.
- The car can be driven immediately after the flash. It does not have to sit at the dealership. The temperature compensation will not be normalized until the vehicle has sat for 8 to 10 hours. Where and when this happens is irrelevant. When the vehicle sits for 8 to 10 hours, the temperature compensation will then be normalized.
Confusion about the cost to the customer.
- $350.00 MSRP, which includes the calibration and installation labor.
Confusion about dealer knowledge about the calibrations.
- I have contacted the Executive Director of Global Accessories/Perf Variants/Parts & Motorsports. After receiving an overwhelming number of questions and seeing the customer feedback on the dealer experience with these, Chevrolet Performance is providing an updated dealer bulletin as quickly as possible.
Now I will attempt to go through each MRC package and give a short explanation of the benefits included in the Chevrolet Performance offerings. Again, each chassis package and mode has its own individual calibrations. None are shared between any of them.
Tour Mode
Model(s)
- 2016 to 2018 Base+F55
- 2014 to 2018 Z51
- 2017 to 2018 Grand Sport
- 2017 to 2018 Grand Sport w/Z07
- 2015 to 2018 Z06
- 2015 to 2018 Z06w/Z07
- For 2018 (except Base+F55) MRC vehicles, please see footnote
- Major Improvements in impact isolation and integration – Impacts are softer, and less harsh. When the vehicle does encounter rough roads, the structural feel is greatly improved.
- Major improvements in ride motions at all speeds. Much more balanced and less abrupt. The car is more poised in compression and rebound, resulting in a flatter ride. This is not implying stiffer body motions, but the vehicle exhibits more a more composed ride.
- Parking lot and low speed (25mph and less) the ride motions are more compliant and less jarring.
- Handling is more responsive and much more precise. The response of the vehicle is more exact reacting to driver steering inputs.
- For 2018 vehicles (except Base+F55), some of the final improvements being implemented for the MRC upgrades were part of the 2018 production release. Thus the improvements for 2018 vehicles are also very significant but not quite as dramatic as the 2014 to 2017 packages.
Sport Mode
Model(s)
- 2016 to 2018 Base+F55
- 2014 to 2018 Z51
- 2017 to 2018 Grand Sport
- 2017 to 2018 Grand Sport w/Z07
- 2015 to 2018 Z06
- 2015 to 2018 Z06w/Z07
- For 2018 MRC vehicles (except Base+F55), please see footnote
- Sport also has major improvements in Impact isolation and integration. With these new improvements the impact isolation and integration is better than the Tour mode with the original production calibrations. Impacts are softer, and less harsh. When the vehicle does encounter rough roads, the structural feel is greatly improved.
- Major improvements in ride motions at all speeds. Much more balanced and less abrupt. The car is more poised in compression and rebound, resulting in a flatter ride. The Sport mode exhibits significantly more body motion control that Tour.
- Handling is more responsive and much more precise. The response of the vehicle is more exact responding to the driver steering inputs weather using Sport mode as a daily driver, or carving through a mountain road.
- Parking lot and low speed (25mph and less) the ride motions are more compliant and less jarring.
- For 2018 vehicles (except Base+F55), some of the final improvements being implemented for the MRC upgrades were part of the 2018 production release. Thus the improvements for 2018 vehicles are also very significant but not quite as dramatic as the 2014 to 2017 packages.
Track Mode
Model(s)
- Grand Sport (FE6) and Z06 (FE6)
- The new track mode is better balanced and response to driver inputs are much more linear near and at the limit of adhesion. With the new Track calibration, the redistribution of the damping in the body, wheel, and handling algorithms makes the car more fluid as it is cornered. The rotation of the car is more precise at initial turn in, and maintains its path through the turn. As the driver rolls into the throttle, vehicle heading is better sustained.
- The new Track calibrations increases driver confidence. This, coupled with the vehicle being better balanced during the cornering maneuvers resulted in an average of a 1 second lap time improvement over the original calibration.
- Revised temperature compensation tables. As the fluid heated up, during long continuous and repeated runs, sometimes over 100 degrees Celsius (212 degrees Fahrenheit), the damping is effected, not only on an absolute basis, but also the front to rear effecting the balance of the car. New temperature compensation tables were developed to make the balance of the car much more consistent regardless of the damper fluid temperature.
- Grand Sport w/Z07 and Z06 w/Z07
- Both of these foundation Track calibrations are included in 2017 production.
- The foundation calibrations are solid performers as indicated in the Z06 w/Z07 VIR lap times of 1:55.95 on the full course and 2:39.77 on the Grand Course. The lap times for Grand Sport are 1:59 on the Full Course and 2:45 on the Grand Course.
- As explained in the Grand Sport FE6 and Z06 FE6 Track mode paragraph, the new temperature compensation tables are now included in these Track calibrations as part of the Chevrolet Performance offerings and 2019 production.
Upon the completion of the track calibrations I rotated several of our track development engineers with different driving styles through the cars. The result is what the best balance is based on each driving style. If more understeer is desired, this can be easily accomplished by purchasing and installing
- Front Stabilizer bushings (Z51 w/MRC, Grand Sport non Z07, Z06, Z06/Z07) part number 84402110 (available February 2018)
- Rear Stabilizer bushings (Z51 w/MRC and Z06 w/Z07) part number 23305975
- The bushings are easy to install and cost about $6.00 each
If even more precision is desired, Chevrolet Performance also offers lower control arms with stiffer bushing.
Well, that’s a long explanation, but it’s a complicated situation which is why we assume the question was over overwhelmingly voted for and asked in the “Ask Tadge” forum.

NOTE:
Headline Details Page 2 of 6
https://dealer.autopartners.net/port...US-9-4986.aspx 1/31/2018
The MRC damper system hasa built-in temperature offset correction as part of the calibration.
Chevrolet Performance recommends allowing the vehicle to sit for 8 to 10 hoursafter flash of
Calibration and prior to spirited driving. This step does not need to be done at the dealership and
can be done at the customer's convenience. Allowing the vehicle to sitwill allow the damper
temperatures to normalize, and the temperature offset in the calibration toaccurately reset. The
vehicle is still functional prior to sitting for 8-10 hours. However, thetemperature offset correction
will be less accurate, resulting in a less optimized operation until the dampertemperatures
normalize.

I really appreciate the detailed response and I do also appreciate the effort it takes to release something on a past model while working on future ones.
I am particularly interested in 2015 Z51 Track Mode updates and judging from this: "A new Z51 track calibration is on my “things to do” list, but my “task at hand” list is much longer." I probably should not hold my breath until it comes out.
thanks

That is the type of answer that makes this section so valuable. Big thanks to Tadge and Jim for taking the time to respond!
Now what about these lower control arms with stiffer bushings, that's the first I've heard of that. Anyone know the part number?
BTW, this was me reading the reply

This is one of the best responses yet. I do not have MRC and I thoroughly enjoyed the question and answer provided. Even moreso though, I got giddy just knowing that Mero and team read the forum to some capacity and even see the Ask Tadge poll. To me that is the sign of a manufacturer and team that loves what they do so much that they actually get engaged at a personal level.
I already had a lot of respect for GM and the Corvette brand before this, but now I have even more. Thank you Corvette team for solidifying that I made the right decision choosing to drive a Vette.

As a owner of a C7Z Z07 2015 and a decent driver, do you think i will actually feel the difference? Without pushing her to the limit? Which i want to! But im no fool, i dont have the capabilities of pushing the bloody potential of my Z06! So thats why i wonder if its gonna worth it for me!

Great response from Jim - thanks very much!
I just had the calibration done a couple of days ago on my 2016 Z06 w/ Z07. It took the dealer literally hours working back & forth with GM to finally figure out how to do it and how to bill it.
Contrary to what some people "in the know" wrote in other threads, it definitely costs $350 that the customer pays, and the installation costs are the part that the dealer charges back to GM through an operations code. SO IT WILL COST YOU $350.
The biggest change I noticed was Tour mode. Before the update I really hated going into Tour mode because the car was tremendously "floaty". (It was nothing like that in my old 2014 Stingray Z51 -- this was something new with the Z06 w/ Z07.) It was like the rear end was on springs. After the update it was like night & day, with the car reacting to bumps like I would expect it to, and the floaty feeling completely eliminated.
The other thing I noticed in Tour after the update was that the steering seemed much more sensitive -- in fact, too much so for my taste. So I changed the option to always use Sport mode steering.
So it's an interesting driving experience. A more compliant and predictable drive, while I can still very much feel the road.
Unfortunately it's winter here in the Northeast, so I won't get much driving time until the Spring to really explore the update. Cup 2 tires in the cold is not a good combination for pushing things. I am looking forward to opening up in Sport and Track modes to feel the extent of the changes.
However, what I've experienced so far makes the purchase entirely worthy. I would absolutely recommend dropping the $350 for the upgrade.

Well done on the explanation as well as the decision to roll this out for customers. It gives the customers from previous C7 years the choice to purchase this enhancement, which allows them to benefit from R&D that occurred after they purchased.
It inspires trust in the brand.
Thanks,
Bill

Thanks Tadge and Jim. And thanks to GM for allowing these excellent explanations to forum questions!
When the update is available for my 2017 Grand Sport, will purchase. Worked with the Petty Team years ago (as a sponsor) and understood how complicated is was to adjust mechanical shocks to balance the compromise needed for each track, specific bumps and how the driver was a key element.
From what you said and the fact that I enjoyed driving my modified Corvair guess I won’t mess with the stabilizer bushing if it currently has a slight oversteer! Sure doesn’t feel it, but my limit is reached in tight turns as I don’t Track.
PS: As you noted, it is driver dependent. Even in oval racing with the same conditions some drivers wanted some understeer, some oversteer. Or in NASCAR terminology, more Tight or Loose. That was changed during pit stops with a rear spring adjustment by turning a lead screw on it’s mount. Driver might say give me one more turn, which they may do, but if the crew chief thought it wasn’t needed, i.e. track was changing or it was really a tire that they were changing etc, they might tell him they did and really didn’t! Even if they didn’t make an actual adjustment and there was no tire change just a fuel stop, when he got up to speed he’d say “that’s better!”
The first few years of our sponsorship, Richard was driving. When he asked they did it!

I have a 2017 Z06 so I assume I will need to get this completed if I want all the features. The bulletin number would be great when it comes out as my dealer doesn't seem to know about changes unless I give them the bulletin number and confirm that they get it right.
I'll keep my eyes peeled for it. Thanks for posting this information and why I love this forum.

Thanks for the detailed explanation, but there are still unanswered questions with regard to the '18s, given the pre- and post-plant shutdown production cycle of the '18 MY.
I take it the final 21 MRSC calibrations were not quite ready when '18 production started, but you say those final tweaks were completed in September 2017 after plant shutdown. Then I read 18's got some, but not all of the improvements. However, 18's are still being produced until the end of Jan, and one week later, '19 production will start.
So, my question is would a 2018 Z51, which has not been built yet (e.g. mine w/ a 1/15/18 TPW) or one that was built after the plant re-opened in November 2017 (and after '19 MY calibrations were completed 2 months earlier), come with the very latest MSRC calibrations, with no need for the $350 update?
If not, why not?

Did anyone else realize Jim said the Z with the new Calibration did a 2:39 @ VIR? Does that not beat the now discontinued Viper’s time?

Does the $350 MRC update have any effect on safety, which is Stabilitrak (AKA “active handling”), and, ABS? The write-up only seems to mention handling, ride quality, and, driver confidence.
I’d just like to know if my 16 Z06 (when all safety systems are on) is just as safe w/o the update.
