Tune your magnetic shocks from Ride Tech for the C7 suspension! Very trick!!

A passive damper is tunable by force versus velocity...it will create a specific force when it sees a certain piston speed. In addition, by manipulating the precise design of the piston and shim stack, you can influence the length of time that this force is available (within a very narrow window) It doesnt really know what G load you are in, how fast the car is going, nor if the brakes are on or off.
With an electronic damper (MagneRide or otherwise), not only can you create a specific force, but you can do it as a function of g force, brake pressure, steering input, and vehicle speed. AND you can hold that force for as long as needed. Example...trailbraking is a technique used to keep the car on its nose through a corner to increase front grip. With a passive damper as soon as you let up on the brakes, the damper releases the rebound force and the nose comes back up and you start to loose front grip. With the OEM tuning, its even a little worse...trail braking tends to confuse the antilock brake system and you can get an ice mode or rock hard pedal situation.
Now imagine tuning the system so the rebound is not released until it sees a decrease in G force, a decrease in steering angle, and an increase in throttle position. At the same time you are releasing rebound force in the front, you could be releasing compression force in the rear to allow the car to transfer weight and increase grip to the rear for better accelleration.
Another example...a slalom. A slalom is simply a series of abrupt corners strung together very quickly. Such a scenario doesnt really exist in real world driving. Passive dampers struggle with this scenario...by the third cone you are typically slowing up to keep the car under you. Since OEM tuning is so narrow the results are not much better, sometimes worse if the stability controls get involved.
We can tune each corner of the car independently, AND extremely quickly...and in a wide range. Magnetorhealogical fluid will turn from water to peanut butter and back to water in less than 20 milliseconds. If the entry to the slalom is to the left, we may increase the compression on the right front and increase the rebound on the left front and left rear. As the car transitions to the next manuever to the right, we start to reverse all that...more compression on the left front, more rebound on the right front anf right rear....as determined by G force, vehicle speed, steering angle, and throttle position.

When you are trail-braking, the car is on its nose and slowly moving to being on its side as you release the brake pedal and start to turn the steering wheel, but the motion is rather slow in terms of damper shaft movement after the very rapid change when you first apply the brakes. How do you keep a high force from the damper with only a very slow movement in the damper shaft? Is the damper force not related to the damper shaft speed?

Just curious what your experience has been in "failures" wether the shock itself or sensors due to the extended activity. In your experience since you have "pounded" on these systems during your R&D, have to found any weaknesses or areas that need to be modified on our existing OEM systems ???
Finally any experiences with your customers warranty given your system is "taking over" the management of "their /OEM" systems ??

You will find that when the ECU sees little G load, it understands that you are not racing and absorbs bumps and potholes accordingly.

I'm looking forward to testing the settings out come spring, feel free to post your results if you're in a warm weather climate testing now.
Very informative posts RideTech!

I've been following the DSC setup for a little while now and have been very interested. Trying to wait for some more end users to post their experiences. In regards to "canned tunes" what does the end user have a options. What does the unit come with out of the box.
also any data comparing suspension and shock setting for track settings on the stock ecu versus the capabilities of the DSC controller?

I too have been following this thread with interest. However, I have a different reason than most (if not all) of the people following this thread. I don't track my car. I use it for daily commuting, vacation getaway, and lightweight canyon carving. My priorities are good ride when not using the great handling capabilities of the car and confidence that I can stay in my lane when I am. I don't mind the current ride but it wouldn't hurt to be more compliant during daily activities (more so for my SO). The roads on my commute are not the best. Similarly, when I get into the twisties on roads with rough surfaces the car will shift under the lateral Gs when the tire looses contact with the road. So, I have a few questions:
1) How significant would the increased compliance be for daily activities?
2) Would there be a significant increase in cornering ability on rough roads?
3) Are there canned tunes for my conditions?
4) I have an extended warranty (GMEPP that covers the MSRC shocks). How visible is the system when I bring the car in for service? Will the dealer see it when he plugs in his computer if he is not specifically looking for it? I'm assuming that if I had a suspension problem I could put the original module back in without creating any problems prior to bringing the car in for service, correct?
Thanks

Been looking at this from the start for the car. Cant wait until some guys put this on the car and get some feed back on it.
Doug if no one post in here before you guys put it on a car please give me a message on it and what you really think on it. Crap for no more than 1300.00 not bad at all for a good up grade in the car. Robert

The Magnetuner directly replaces the oem suspension module located behind the drivers side wheelwell, invisable unless you remove the inner fenderliner.
I honestly cannot answer the warranty question. I would suspect that if you had a damper failure...AND a picky dealer, that they could deny warranty on that particular damper. Unlike an aftermaket engine tune, I cannot imagine what damage an aftermarket shock tuner could do. You can always re-install your oem suspension module if that situation arises.

From a traction standpoint how much improvement do you see?
Something you ever tested?
I'm at 640rwhp and am amazed how much traction I have. I was going to do a Z06 body because I'll be at 700ish rwhp next spring and I figure I was already on the edge power wise with the tires. I don't think torque will jump more than 25-30ft lbs, at 614 now.
Wondering if getting this maybe would be a good, and less expensive in between to get some more power down.

This was the thread I started reviewing one of the first Magnetuners released. I am very pleased with it and look forward to next track season!

Here is also my review from earlier this year. I've had this system on my car for the entire last season and absolutely love it. I dropped 2 seconds off my lap time at VIR with it and the ride is better than street.

I don't track my C7 because of the SC but even for the street, for the cost seems like a no brainer upgrade. Your comments about some slight 2nd gear wheel spin to zero spin and hooking got me.
If it can help put extra weight across the back end without sacrificing at other times its well worth it.
Doug do any of your ECS shop/nearby customer cars have this and how has it helped? I suspect your in the same boat as me for the time being with snow on the ground but very interested.
On the list for spring.
