1M E92 E92EDC E90EDC E93EDC

The E90EDC + E92EDC and non EDC have the same length

In the 1M front dampers the body is exactly the same as E92 but the shaft goes 8mm less out.
I don't know if the shaft is shorter or if simply the internal higher bump stop is thicker in the 1M dampers???????? maybe someone could fin this out???
The same for the rear, body the same but shaft going out 6mm less

I found that the E93EDC front left damper has the shaft as short as the 1M damper, but the right damper has the same as the E92 damper!!!!!
This is completely crazy, I thought the E93 damper was defective, I bought another 2 E93EDC dampers and exactly the same, one is like the E92 the other is shorter like the 1M.
Is intentionally by BMW to make different length dampers L/R???? I could not get my hands on rear E93EDC dampers to compare....
Interesting, what testing did you do, or for what purpose? Any graphs? R u also considering EDC retrofit?

Dackel, which versions did our current EDC god end up installing on his 1M?

For the moment I plan to put E93EDC shocks with H&R springs, E36 bump stops, front shaved mounts on my 335i

and then control the EDC simply by varying the current to have "static" settings like soft and sport

I already have complete M3 rear axle + M3 LSD + front carriers with E92M3 dampers! and front + rear M3 brakes

Yes I am doing what BMW did to the 135i to become an 1M
I am doing a 335iM

How's the setup working for you?

Can you share how you build the 'DIY' EDC current drivers? Does anyone have any info on the EDC's electric resistance behavior (assuming LR)? Did you measure the original EDC drive signals? PWM? Carrier frequency?

Still in the works... pause for summer break.

I am still looking for someone near me with an M3 so that I can scope the signal going to the dampers.

It is for sure PWM driven, but need to know the frequency Hz of the signal...

Anyone can help on this?

I am sure there are lots of people who likes the idea of EDC or variable/adjustable suspension systems for a variety of reasons. Sure I am not one of them. In my opinion it is essentially the driver who must adapt his driving style to different road conditions and learn his car and there is nothing wrong or incomplete about that principal. A fixed suspension/ride is like one of the very fundamental reference points a driver can and should learn about his/her car which makes it possible for the driver to trust how it behaves on different roads and conditions and so we know exactly how the car will react when you do something right or wrong. I understand people choosing a "different" set up than the stock one because they may like that different feel or set up better than the stock, but it is more blurred for me when it comes to the logic behind variable and electronically controlled systems.

There are ways to get what you exactly want from your car without introducing EDC to the menu and in the case of 1M I believe better tires (and maybe 18 inch wheels) are just more than enough for most both on the road and occasionally on track. For people who likes to get things more precise there are camber plates and a few other simple, proven and cheap tricks as well.

In short, the 1M suspension is just fine, rides fine enough too especially with proper tires and some say on 18 inch wheels it is even better and I bet it is. One of the things that I love about this car is it doesn't have everything "adjustable" like every other modern gadget we have in our lives, you need to work it out and adapt yourself, respect to it and try to optimize what you have in hand. One less thing to configure before you even start driving, beauty!

Maybe I wouldn't even consider 1M if it had every option available like EDC, auto box, active steering etc. It is what makes the 1M special, a straightforward and old school solution which proves to be working great because it is designed as a one single set up by its engineers, an integral and harmonious unit. It doesn't have plan Bs and Cs in its genes.

Just food for thought, no one should take any offense and sorry if I took it a a bit off topic and probably too long as well.

+1. Well said.

KW DDC, cheaper, easier more adjustable.
GL anyway.
