Testimonials from C6 ZR1 owners:
Steve Odian – 2009 ZR1
I just had the magnetic ride control software installed in my 2009 ZR1. The difference is incredible. I used to cringe when approaching bumpy roads. Even in touring mode it felt like the tires were bouncing off the road and the ride was eye popping.
That’s in the past now. Now in touring mode the car is much more planted, handles much better and the ride has been vastly improved.
I can’t say enough good things about this upgrade. It was well worth it.
Anyone with a C6 with magnetic ride control should consider getting this upgrade. You will not regret it!!
Mike J – 2013 ZR1
Oh my gosh Jim, what a difference! Shortly after your MRC upgrade, I traveled 18 miles north to La Grange, Texas. The New Tour setting took out the harshness of any bump or dip and the steering response was noticeably sharper. When I approached the bluff, I switched to the Super Sport setting, which allowed me to carve up the 6 turns of the bluff at a speed I didn’t think possible! I had so much fun, I ran it four times!
So with a smile on my face, I look forward to more spirited driving with my “new” ZR1. Thanks for breathing life into her!
Chris – 2012 ZR1
Had mine done 12/24/20. Definitely a noticeable improvement! Touring mode is much more comfortable to drive/ride. Super sport mode is a blast with excellent feel! Had a chance to test it out on the toll road and was definitely a marked improvement!
Drew P 2009 ZR1
night and day difference entirely! it quite literally feels like a brand-new suspension was put in…the tour mode actually absorbs expansion gaps and lane reflectors.. i can feel sport now too! now Jim, thank you brother! –drew
Evan G – 2012 ZR1
Got the Mag Ride software updated by Jim Mero yesterday, and it was immediately noticeable. It doesn’t make the car ride like a Cadillac, but there’s a noticeable improvement in the ride in both Tour & Sport. In Tour, on rough roads with dips, bumps, broken pavement, patch jobs, etc, you’ll immediately be able to tell a difference as the car will absorb them much better. As to Sport mode, you can now use it. It honestly feels very similar to the new Tour mode on smooth streets, but you can tell the car is controlled better. You can now use Sport mode as your everyday driving mode. Overall the upgrade is very similar to what GM did on the C7 Mag Ride cars with their updated software.
I have a 2-lane backroad near my house that I drive constantly (use it as my primary route to avoid a major road that gets backed up). There are a lot of patch jobs (some not very good), rough spots, bumps, etc. With the stock tune and using Tour, you feel every one of them, and I would cringe when I hit some of them. With Jim’s tune on Tour, it’s almost like driving a perfectly smooth road. Most of the impacts just disappeared, and it let me enjoy driving the road much more. It also made the car more stable as many of these impacts occur mid-corner, and it used to upset the car causing me to have to make a steering correction. Now most of these impacts just don’t bother the car at all, and no longer need any steering adjustment.
If you’ve been thinking about doing it, don’t wait anymore and get it done. If you haven’t looked at it previously, you owe it to yourself to consider it. The GM Mag ride update was the best mod I did to my C7, and I’d say the same thing about Jim’s update to my ZR1.
Bruce B – 2012 ZR1
Got the MRC module installed and what a difference. You are still at 100 percent customer satisfaction. Thanks again for offering C6 owners a chance to have a comfortable ride and better handling.
Derrick D – 2013 ZR1
Jim came to Houston 23 Dec and I had my “13 Zr1 upgraded to his “Super Sport” trim. I had a 40 mile drive home and noticed the difference immediately! I always have in in “Sport mode” and feel every bump and expansion joint in town and Hwy. After the upgrade, the ride was more “refined” but yet still firm and didn’t get “jarred” all over the place! Dare I say smooth ride! It was time and money well spent! Kudos!
Ted A – 2010 ZR1
Best money I ever spent on my ZR1 to date. Jim Mero’s mag ride update.
Erik – 2009 ZR1
I live in Michigan and Jim and his wife were kind enough to meet my wife and I after work at his house and do the programming there. I really can’t overemphasize what a positive difference then new settings made for my 2009 ZR1. On Michigan roads, with our unpleasant winters, we have sizable potholes and extremely aggressive expansion joints. The ZR1 was almost undriveable on the highway in stock form. Jim’s calibration changed it so I could commute, weather permitting, every day. It really was a game changer. Thanks again, Jim.
Dustin B. – 2013 ZR1
Thank you Jim….The ride is much improved and comfortable now. I find myself using the new sport mode mostly during my drives, and I only catch myself using the new touring mode on a rough road. Overall, I am very pleased with the new mag ride suspension setup. My two current settings, tour and sport are vastly better than the factory ZR1 MCR settings- which felt like a bomb going off when hitting a bump or pothole in the road
Jay W. Panama, Central America – 2011 ZR1
Finally can have joyrides with the ZR1. Car feels easier or nicer to drive, I can drive it a lot more now that does not feel like a race car suspension. Now it feels like a sports car that you can drive and enjoy every day without feeling pain for every little bump on the road. So happy I can play with the car more often. Thanks so much.
Jaron P – 2010 ZR1
Hi Jim, You’ve overwhelmed me with This MRC unit. I have changed/customized/replaced so many parts of my c6 ZR1. This is the best improvement I have done, and it’s not even close. I noticed the massive difference as soon as I got on the highway. If I listed the modifications, I have done it would look like the credits in a movie script. Again, unbelievable! I love the new super sport! How do you do it? It’s a completely new car. Blown away, just blown away.
Bob G – 2009 ZR1
I now love my 2009 ZR1 even more. The MRC upgrade is simply awesome. The steering has more feel and firmness just when needed, perfect. The suspension is really a noticeable improvement. More forgiving over the rough stuff yet the car settles in faster. All around more comfortable and highly manageable when driving aggressively. Way fewer “fall out clunks” going across overpasses and road bumps. Thank you so much for the upgrade, love it!
Arnold – 2012 Centennial ZR1 – Upgraded at Charlotte
Jim, I had you do the upgrade to my 2012 Centennial ZR1 at the Rick Hendrick Corvette show in Charlotte. The ride back to Greenville, SC was remarkable. The car rode so much smoother. Before the upgrade you would cringe going over road construction areas. I am very happy with the upgrade.
Namala W – ZR1
I took the car out to get some pictures, just drove it around in tour mode. I was so shocked by the improvement in ride quality I ended up taking it for a long drive. I took the car over a route I know that is very bumpy with both rolling bumps and short harsh bumps. I really couldn’t believe how well the car completely eliminated the smaller bumps and was so composed over the longer bigger bumps. On larger bumps I’ve always felt the rear of a C6 would pop up and “hang” a brief moment longer than the front of the car. Your calibration removes that sensation entirely. Both Steve and I like to go on long road trips south to Nevada and California, typically 8-10 hours a day behind the wheel. I thought to myself that this was the perfect calibration for a trip like that as the car was so comfortable, I actually felt I would prefer to do a long trip in this car over a CTS-V2 or CTS-V3. I will be recommending this upgrade to all our clients with MRC
Ed H – ZR1 – Upgraded at the NCM Caravan
Thank you for doing the upgrade to my ZR1. I noticed an immediate and impressive improvement in the way the car rode and handled over rough surfaces using the new calibrations. During my 5000 Km ride back to Edmonton, Alberta, over many types of roads I found the car was no longer jarring and shaking the car to bits at every imperfection as it was doing prior to the upgrade. Changes in road height, such as at the joints at highway interchanges and railway tracks, are much more pleasant to traverse. I found myself enjoying the ride rather than hanging on for dear life. These C6s can actually ride like a car, not a wagon! This would be for a great upgrade to the new owner should I ever decide to sell the car. However, with the new settings I may just hang on to it for a while longer!
Mike P – 2011 ZR1 – Upgraded at Carlisle
Hello all.!! Wanted to give a shout out and a BIG “Thanks.!!” to Jim and his wife Terri.!! Ran into them at Carlisle this weekend and did Jim’s MRC upgrade on my ZR1. Man, what a difference it made with the car, a buddy of mine had it done on his as well and had the same opinion.!! I honestly felt the difference leaving their tent, going back to where we parked.
Then on the way back to the hotel, highway speeds, the car just absorbed the road beautifully.!! This is with hard, stock, 9 year old tires too.! I did 870+ miles on the way home Sunday, the car was simply a pleasure to drive…it’s gonna make me buy new tires though.!!
Honestly, if you’ve thought about this mod, go ahead and do it. For $325, I promise it’ll be the cheapest mod you make with the greatest results. Worst thing that happens, Jim puts you back to stock and gives you your money back.!!
Thanks again Jim and Terri.!! It was a pleasure speaking with you guys and truly love my upgrade.!!
Mike P.
Sean A – 2011 ZR1 – upgraded at Carlisle
I can’t say enough about how dramatic the improvement in the ride quality of the car is. The new tour setting is super smooth and stable which makes for a great grand touring setting. The super sport setting is very firm but still much more composed that the old sport/track setting – in some high speed turns the car is very flat and I can feel the rear planting on power. I can’t wait to try it on the HPD event in October. Thanks Sean
Mark W – Carnon, France – ZR1
I have received your controller. Thank you so much!! We have changed the original with yours, and the result is phenomenal!! Cornering is like with my C7 Grand Sport, nothing to do with the standard. There is à ‘’special corner’’ leaving the High way, to my home, he is 270° twisted, and only one line (very narrow, absolutely no space, if you slip you are going directly into the barriers) à real challenge to go fast here, without breaking the car. This corner my personal record with the Micheline PS4 and the standard calculator was 0,98 G. (alone in the car) The first time I tried your calculator with Micheline PS4 (two in the car – The tuner and me) 1,10 G ! I am really happy. Thank you so much Sir, hope to get your news. With all my respect and all my friendship, Mark
Chris Z – 2010 ZR1 – upgraded at Carlisle
It was great meeting Jim and his wife at the 2019 Corvettes at Carlisle. I asked Jim to perform the software modification for my Magnetic ride suspension which was – New Tour and New Sport mode – on my 2010 ZR1.
Prior to the upgrade, I could not tell the difference between the stock two modes and often thought, “Is the mag ride working?”.
After Jim performed the upgrade, the New Tour and New Sport mode was noticeably different.
The NEW Tour mode made the car feel like I was gliding over the road with less side to side roll, which was noticed prior to the modification. The small bumps, and annoying road cracks are all but gone in this mode. We drove the car home in tour mode for 200 miles and loved it.
The next day I took to car out to check out the New Sport mode. All, I can see is I was grinning ear to ear in this New Sport mode. Prior to the upgrade, I rarely ever used the sport mode, since I could not feel a noticeable difference from tour. Now the car is really fun to drive. In this mode, the car feels dialed in when taking hard corners at speed. I felt more connected to the car, and the car feels more predictable. I absolutely love this mode and is now my favorite mode when driving.
Thank Jim!
Chris
Mark M – 2011 ZR1 Programmed at the NCM Caravan
Jim Mero thanks again, absolutely love the new Magnetic Ride Control upgrade, my ZR1 rides and behaves so much better. By far the best money I have ever spent on this car!!! Highly recommend to any C6 owners with MRC. We made its back to Southeast Texas so I’ve put about 1000 miles on the new MRC calibration upgrades and all I can say is WOW they are absolutely fantastic, the jarring harshness on rough surfaces is gone, the car seems much more planted. Thanks again for greatly improving my suspension and the time you gave us just talking.
Lawrence C – 2009 ZR1 – Upgraded at the Caravan
It was A Pleasure meeting you and getting the MRC Upgrade Vette rides a lot better more balanced smoother on bumps I’m glad I did the upgrade. Really Enjoying it! Thanks, And God Bless You!
Bob S – 2011 ZR1
I want to thank you again for going out of your way to flash my car, I really appreciate it. After driving the car around I really feel the difference. I like driving the car even more now, if that is possible. The car goes over bumps and rough roads so much better in both touring and sport. I love the steering in both as well. I can’t wait to take it down to the roads you told me about in southeastern Ohio. Thanks again for upgrading my car.
Rhett L – 2009 ZR1 – Programmed at the NCM Caravan
I had my 2009 ZR1 upgraded by Jim Mero. At first, I could not tell a difference the roads were really nice and smooth at the resort down to bowling green. Got back to the hotel and took a little cruise up to the museum. Saw the road that makes you say this is going to hurt. Almost smooth as glass going over that patch and dip. Now I am looking for some test roads to try out the tour and sport settings. Real everyday test will be when I get back to Texas roads. Thanks for signing my ZR1 #136. Jim Mero.
Jason M – 2011 ZR1 – Programmed at Carlisle
I have to agree with your comment about the new tour and new sport. What a difference it made on my ZR1! Both tour and sport glide over bumps, the body motions are much more balanced. Steering is more responsive. It’s still a Corvette but no more dash rattling over the bumps.
Larry R – 2011 ZR1 – Programmed at Carlisle
I had my ZR1 done at Carlisle last weekend. It only took a few minutes. The cars ride is so much better i still can’t believe it is just from reprogramming. Feels like a new and better car.
Larry – 2011 ZR1 – upgraded at Carlisle
I had the MRC upgrade done to my 2011 ZR1 on 8/23/2019 at Corvettes at Carlisle PA.
The upgrade that I picked was the “New Tour 2 / Current Sport (Track)” option. I chose that option for two reasons. First, to give me the “stock” sport mode for when I am on the track or the twisty fresh paved roads I sometimes come across. And second, for when my wife drives with me on not so new roads.
A little about me. I don’t work for Jim Mero or have any affiliation with him or his company. I don’t work in the automotive industry and am not an engineer, actually I am in the investment business. I am also not a race driver, but do enjoy the track lessons and time on the track a few times a year. I chose to have him work on my car based on his reputation experience and personal recommendations from members of my Corvette club. I paid full price for the upgrade and was not offered any discounts or compensation for a positive review.
First Jim and his wife are very nice people, friendly and care about what they do. After you meet them you would invite them to your home for dinner. The upgrade appointment was on time and done in only a few minutes. One of the things that helped me personally bite the bullet on this upgrade is that no suspension part needed to be replaced, it’s all electronically uploaded. Jim Mero offers, that if you don’t like it he would put it back the way it was and refund 100% of your money.
My review from a not engineer may help other non-engineers get a feel of how I perceive the upgrade. My first two rides after the upgrade was a 30 minute rides from Carlisle PA to my hotel and back the next day. At first as I am changing the modes on the changing roads it was a bit hard to tell if the control was doing anything or was the road just smoother on the section of road that I put in New Tour 2 mode. I did not believe that difference could be just from the MRC. In both modes the car tracked flat and stable on the on and off ramps without any noticeable difference in body-roll at moderate speeds.
The review of the upgrade on the highway from Carlisle to NJ was much more informative because of the miles and road variations I encountered. The car rides much better in the Tour 2 mode then the stock Tour mode. The best way I can describe the ride difference now between changing from sport to tour modes is it’s like being able to change the sidewall aspect ratio and compound of the tires on the fly as for as smoothing out the bumps on the road. I would veer off the side of the highway in each mode and can feel the difference in how the shocks handle the bumps at highway speeds. Much better than before the upgrade. Now when I switch to Tour, the bumps on the road almost go away and I feel that the car is planted on the road, especially on bumpy turns. The car handles better in tour mode than sport mode now on the road most of the time, since the roads are not in such great shape by me,
Before the upgrade I would drive in Sport mode most of the time. Now I am driving in Tour mode when I am not on the track or very spirited street driving. This upgrade has simply improved the ride quality of my Corvette in real world roads without giving up any of the performance of the car on or off the track. I would recommend this to anybody that has a C6 Corvette with magnetic ride control as one of the best upgrades for the Corvette. If you have an early C7, my understanding is that you can upgrade to the new MRC programming at the dealer. All this for less than the price of a new tire, what a great deal!
Thank Jim!
Jason M – 2011 ZR1 – upgraded at Carlisle
Jim, thank you. I cannot overstate what a difference the upgrade did with my ZR1. I am beyond amazed with the improvement it made. Thank you again and it was an honor to meet you today!
Bob D. 2009 ZR1
Jim, I put the unit in today, very noticeable upgrade. The tour setting is significantly more compliant and feels much more under control. Bumps that would usually unsettle the suspension don’t have that issue anymore. The sport version was also very good. My wife wants one for the convertible pronto. Thanks, Bob
Rob W – 2013 ZR1
Just picked my 2013 ZR1 up from having the Jim Mero Vehicle Dynamics MRC upgrade. I did the controller exchange program and have already shipped my original controller back to Jim.
I went with the New Tour/New Super Sport combination. The difference in New Tour and the original Tour mode is night & day. I’ve driven it over some really rough roads (we have a lot of them in Tulsa) and ride improvement is substantial. So far, I’m very happy with the purchase.
JB, North Charleston, NC – ZR1
I too got my ZR1 Mag ride upgraded with the Jim Mero tune. I did the Controller exchange. He mailed it Friday and I got it today (Monday), right on time to do the install once I got home from work.
Thanks to his YouTube channel and the video on how to remove it, this was straight forward.
Before I made the mod, I took out the car to run an errand in order to get a fresh feel on how the car felt all stock. Once I got home, I did the install and took the car back out for a quick spin around the neighborhood where I know a couple of spots that usually rattle my teeth out.
Very pleased with the new tour/sport mode. The tour mode is excellent, it smoothed the car over regular bumps. When I switch to sport, I can feel the car tightening (if that make sense), but still, not as hard as the original setting (rattle you to death really in comparison).
I’m pleased with the results; this is what I was looking for.
Rest assured this was an easy transaction and a fairly easy install.
Josh H – 2010 ZR1
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.
Blake L – 2009 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.
