2012 to 2013 Z06/Z07 w/Magnetic Ride Control Shock Calibration Updates

There will be several new shock calibration options available for the Z06/Z07 w/MRC. For the purpose of discussion, I will use the nomenclature New upgrade/New upgrade.  This represents the calibrations that will go in to the current Tour/Sport modes.  I realize some of the terminology might be confusing, so I have provided a graph at the bottom of the page showing the differences in damping between all available modes.

𝐅𝐢𝐫𝐬𝐭 𝐬𝐨𝐦𝐞 𝐛𝐚𝐜𝐤𝐠𝐫𝐨𝐮𝐧𝐝:

The 6th generation Corvette has 2 MRC modes indicated; Tour and Sport. The MRC selection switch should have been labeled Tour and Track, because that’s exactly how they were tuned.

In comparison, the 7th generation Corvette has a three-mode switch; Tour, Sport, and Track. The Sport mode has about 150% to 200% more damping than the Tour Mode. The Track mode, depending on the algorithm, has anywhere between 200% to 500% more damping than the Sport mode.

These increases, for the most part, also apply on the C6 when considering the Sport mode is really a Track mode. The amount of damping between Tour and Sport (Track) can range from 300% to 700%. This amount of damping for a customer who does not track their car dramatically exceeds the desired amount for a “true” Sport mode by a factor of about 300% to 450%. The “true Sport” is described in the New Sport section below.

The combinations that will be available for the 2009-2013 Z06/Z07’s w/MRC are listed below followed by a detailed explanation of each calibration.

  • New Tour/New Sport
  • New Tour/New Super Sport

New Tour Mode

  • 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 a more composed ride.
  • Parking lot and low speed (25mph and less) 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.

New Sport Mode

  • As previously stated, the current C6 Sport mode has 300% to 450% more damping than is necessary for a “true” Sport mode, like the C7.
  • For these upgrades, gone is the “Track don’t call me Sport” level of damping required only for the race track
  • The new Sport mode is a “True” Sport mode, developed using the exact same tuning philosophy as the C7 Sport mode.
  • Therefore, currently, if you track your car, the upgrades are not available at this time.
  • Sport also has major improvements in impact isolation and integration. With these new improvements, the impact isolation and integration are 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 reacting to the driver steering inputs when using Sport mode as a daily driver or carving through a mountain road.
  • Parking lot and low speed (25mph and less) ride motions are more compliant and less jarring.

New Super Sport

  • Super Sport is for owners who like very aggressive body motion control.
  • Super Sport is a global 30% increase in damping over the New Sport mode.
  • The body motion control is more tied down, yet still balanced compression to rebound.
  • The impacts will be firmer than the new Sport mode, but they are better than the original production Sport calibration.
  • Steering response will be improved

TESTIMONIALS

Last year I purchased a C6 Grand Sport convertible.  I bought the car in Texas and drove it back to Michigan.  In the fall of 2018, Jim asked if he could upgrade my car to get my thoughts. The transformation is unbelievable! The pleasure of driving the car in either tour or sport can’t be understated.  On my drive back from Texas I never put it in sport.  Now I do almost all my driving in sport. If I just want a nice cruising car, tour is perfect.  In both tour and sport, the car just glides over the bumps that used to beat me up bad.  Also, I noticed how much better the steering is, which surprised me.  Now I can’t imagine driving the car without the new programs.

Mike, 2011 Grand Sport Convertible

After a total of 10 hours of seat time.  In both tour and sport. Mix of freeway 55-90mph with hours rural backroad and small-town slow driving. I like this new cal so much. Both tour and sport absorb the bumps very very nicely and are still stable and composed.  Everyone will notice a considerable difference. Read More Testimonials ->

Ross W, 2011 Grand Sport Coupe

Jim come to my house to put the calibration in my 2010 ZR1. When I bought the car, I had to drive it back from Texas to Michigan. 18 hours on the road was a bit of a headache. The car was a blast except for hitting potholes, railroad tracks, and impacts in general. Since the calibration, my car drives and handles 100x better. The impacts seem to be non-existent. Going over railroad tracks are a breeze and the sport mode is a true sport mode now. I’m amazed every time I take out my car. Love every bit of my new calibration. Read More Testimonials ->

Josh H, 2010 ZR1

The ride and handling for both modes is a dramatic improvement. As soon as I left Jim’s house in tour mode, I instantly felt a more “modern” feel to the car. Very comfortable now and yet more the handling is more responsive. I do not feel the hard rebound over larger bumps. It doesn’t pound my dash when I go over railroad tracks like it used to. I feel that there is more steering response at lower speeds and of course at high speeds.

When I put it into sport mode, I feel a good difference. Now I feel a nice transition between tour to sport. Before the upgrade, I never put it in sport unless I was showing my friends how harsh it was. I am driving it in sport mode more often now. The ride is so much better as well as the cornering.  I want to say it feels like a new stab bars were installed. It’s that much more balanced through the corners. Read More Testimonials ->

Blake L, 2009 ZR1

Just wanted to let you know how happy I am with the driving improvement. Drove over 250 miles yesterday. I am no expert but would say the car feels much more stable, planted, kind of hard to describe but driving over rough pavement sections has a sense that the suspension is working much more refined. These are really nice cars and your program just adds to the experience. Read More Testimonials ->

Galen C, 2012 Grand Sport

On a regular basis, I’m on roads with rough, heavily-worn asphalt, pot holes, sections of cracked and broken-up pavement and fragmented road edges. For around-town driving, I have MR set in the “Tour” mode and with Jim’s MR cal the car gets over all those crappy road surfaces with a bit more comfortable ride. On roads which are in better condition, but with bumps and heaves, the ride seems more controlled.

When hammering my ZO6 through the twisties in the mountains near my home–State Route 33 from Oaji, California over to where joins with SR166 is a favorite of mine–I put MR in “Sport” mode. With the Mero-calibrated “Sport”, when driving over high-frequency, low-amplitude chatter bumps, ripples, cracked pavement and stuff like that, I don’t feel those disturbances quite as much. Also, Sport, with a Mero MR cal, seems more appropriately-damped in that kind of driving than did Sport with the stock MR cal. Lastly, the car’s response to steering input, especially in an autocross movement or an emergency evasive maneuver seems different. The best way I can describe this situation is that steering is more “crisp”–for lack of a better word.

In short, I was impressed with Jim Mero’s C6 MagnaRide calibration, not only because of the improvements discussed above, but because his stuff is for “real world” driving and not specific to track use. Read More Testimonials ->
