Jim Mero’s MRC software.

[Shrike6]

I just had my MRC module swapped out for one with Jim Mero’s software update. My 2011 Grand Sport has always impressed me with how the MRC can alter the suspension compliance, and provide a good ride when desired. I heard about Jim Mero’s updated software for the C6, and was interested. I read a bunch of people’s reviews, and they were all glowing. So, I had the module swapped out. As I drove back home, I was amazed how quickly I noticed the difference. I had expected a subtle change, but this was instantly noticed. The tour setting was much more comfortable, with less impact harshness, and a more supple, controlled ride. Body motions were lessened, too. I then switched to sport. There was none of the feeling of impact harshness here either, it was firmer, but better controlled than stock. It’s hard to put into words exactly what the overall change is. But, it’s like Jim had another chance to spend more time dialing everything in more precisely. It is a sea change in how the suspension reacts. I can highly recommend it, it’s more than worth the cost.

the ride control is specific for the ZR1......I.E. much better factory stock.....I don't think the JM benefits are much better in that application. although I have no first hand knowledge just hearsay. Seems like it makes a big difference in your application. I have actually heard some folks were disappointed in the swap on a ZR1.

I did it as well in my 427. The ride was noticeably better in Sport and Touring.
