In the same one you had planned to VO code.

Dors anyone know what's the minimum I-STEP required to code CS EDC? My was updated from 58.3 to 60 or 61 in March. Wondering if I'm good to go for CS VO coding.

I have a 2018 non Competition package. Would upgrading to CS EDC work? Im not sure my suspension hardware shocks springs sway bars would calibrate to the CS coding ?

Probably ok to go GTS steering and Trans ?

Thanks for the knowledge if you can chime in

What is the minimum I-Step required to code any CS stuff? I tired to VO code CS EDC but it failed. I assume it's because my I-step version (17-03-503) is not recent enough.

Is there a way to find out exactly which I-Step version? Mine is from March 2017 as well but maybe I couldn't make the cut. I also recently installed ISTA+ (4.01). How can I find this type of info on ISTA+ with or without connecting to the car? If you don't mind sharing...

I am not sure of a way to check I-Step for which you are looking.

For ISTA+, you can use "Basic Features"
Operations > "Basic Features"

Latest ISTA+ is 4.09.x

It was announced last Nov and has been at the car shows for a few months. I assume this is the M4CS (F82CS) then.

US version, yes. M3 CS is not in ISTA+.

They do not use the same edc hardware. Front dampers are different in the ZCP/CS compared to the normal m3/4. Front and rear sways are also different, as are the front and rear springs. Coding the VDC to comp/CS will not help your handling (despite what people say). Coding the ICM and DSC modules to the ZCP/CS config will help your handling though. These modules assign suspension target values dynamically, and VDC just implements those commands to the dampers (for a specific spring rate). If you code VDC to ZCP/CS the ride becomes crashy and poorly damped due to the mismatch of damper and spring/sway rate. I’ve tested this out 4 times now, and I am certain that ZCP/CS VDC hurts the handling of a non-comp m3/4.

What is VDC & ICM?

DSC I understood and assume MDM mode is directly affected as well when I update this to CS.

Also I read that BMW updated their software for lowered cars once they released their HAS kit. My question is what exactly needs to be updated?

Thanks in advance.

Signal path for EDC function is like this ICM->DSC->VDC->Damper.

Other important things...
DSC directs the dynamic behavior of your suspension and e-LSD, even in DSC off mode. “DSC off” mode is really just disablling the safety portion of the DSC module. The other more interesting functions of the DSC module are always active. See the M3/4 technical manual for more details.

ICM relays your driving config (ie comfort/sport/sport+) to the relevant modules and also facilitates module-to-module communication.

VDC is a nigh-brainless module compared to DSC. It simply processes signals from the other modules and outputs them to the damper. VDC is tailored to a specific damper and spring setup (hence the different coding for a ZCP car).

If you really wanted to convert your normal M3/M4 into the CS variant you would need to swap out the front dampers, both sway bars, and the front and rear springs. Doing this would be significantly cheaper than the CS surcharge, so it is actually a reasonable thing to do IMO.

Regarding MDM... yes coding DSC should have an effect. Try driving the car in DSC off mode though. This is the way the car was meant to be driven. In dry, moderate weather it is very safe and predictable as long as you don't drive like an impulsive teenager.

Is there any info on the HAS EDC coding v. CS? I have the BMW HAS coilovers on my f80 and am debating using the CS flash. I already have the most current coding and am running the EDC for the HAS coilovers. All of the rest of my coding is GTS for all. Thanks!

Bringing this back to get some help from the community at large...

Does anyone know the specific coding parameter changes to get this working properly on a '17 F80 M3 ZCP w/6MT? I tried to code this myself but I got a chassis malfunction (which basically turned off the EDC in the car). Based on the info in this thread, talking to a few more experienced coders, and a few other threads on this topic, I did the following:

1. Using E-Sys, I updated my FA with the M4 CS Type code (or Typschlüssel) posted earlier in this thread, including updating the chassis from F080 to F082 in the FA as well.

2. I then VO coded the VCD module, which controls the EDC. No other modules were VO coded with updated FA in step 1 above (as I did not want to lose my other FDL coding).

3. In the VCD module, I FDL coded the "M_Competition/High" parameter from "aktiv" to "nicht aktiv"

Step 3 may not have been necessary as I thought all you needed to do was VO code the VCD module with the updated FA parameters for the M4 CS (which is accomplished with steps 1 & 2). I decided to try it anyway based on some discussion in another thread on this topic - but it still did not work (got the chassis malfunction).

Others have reported getting this coded successfully, even on ZCP cars and/or 6MT cars. My car has pretty new software as it was updated in Dec 2017 - I am currently running I-Step F020-17-11-521. So what am I missing?

One other thought as I am trying to think this through, but I have not verified this yet.... After I restored my original coding parameters, I went to clear the chassis error using ISTA+, as the EDC module did indicate faults (as expecteded based on the prompt I received in iDrive after I did the coding). However, the chassis malfunction error codes immediately returned, indicating a hard fault - 1 for each damper. Digging in the ISTA+ procedures a bit deeper, it appears that to correct the fault, a "EDC start up" procedure needs to be performed. Reading some of the notes in ISTA+, as best I can tell, this EDC start-up procedure appears to "reset" the EDC system.

So, assuming the coding procedure I posted above is in fact all that is needed to program the car correctly for M4 CS EDC performance. Is this EDC start-up procedure required to reset the EDC module so the new M4 CS EDC parameters can take effect? For those of you that got this remote coded, did you notice if ISTA+ was used to reset the EDC ECU after the M4 CS EDC parameters were coded to your car?

I would have tried it myself, but I ran out of time before I could. But it would great to have some more info/insight before I dive back in later on....
