My issue is that my car was not driven for a while and when you fixed it I swapped my winter wheels/ tires on, so I didn't get to compare it right away. I just feel like it doesn't feel as planted in corners with bumps, esp at higher speeds. The GTS diff is a great upgrade though, no more dancing around in the back

Another happy @kubax86 customer. 2018 ZCP 6MT, transformed the car, most notably the GTS differential flash really plants the car and prevents wheel slip. Love the feel of the GTS sport plus steering and the rebound and dampened feel of the CS suspension. And of course with everything in comfort, the car is great for those who are looking for a smooth ride.

It sounds like the CS EDC settings are good for ZCP cars but not for non-ZCP from what I am hearing.

Racer20 did the research on all of this and found that the CS uses the ZCP dampeners, the Base front springs and roll bar and keeps the ZCP rear bar and springs. So for the CS dampeners to work correctly on a Base car, you'd need ZCP dampeners, rear ZCP springs and sway bar. ZCP cars get most of the CS feeling because their dampeners can run the CS calibrations correctly, but you're still missing out on part of the package without the Base front bar and springs and the smaller 19 inch front wheel.

I’ve cs coding with non zcp, it’s not even remotely bouncy, however I have made other changes. I utilized kw HAS and have zcp rear sway bar. Planted is an understatement at high speeds, cornering and high speed cornering. I have no experience with this on stock ride height.

I will be doing the GTS coding with Kubax tomorrow and I will be getting the CS EDC coding done on a non-zcp M3. The car has MP HAS also set slightly below the recommended height from BMW and no other suspension mods. I will report back in how this changes the characteristic of the car and whether I will be sticking to the CS or reverting to original.

Another kubax86 happy customer!
My car had the GTS transmission, no steering modifications and M2 everything else. Updated everything to the correct coding, took the car out and it feels totally different! Steering is really nice, EDC is way better and MDM and Diff are also better. Just much more refined all the way around. Thanks Kubax86!

Another +1 for kubax86 and Bimmer remote coding, process was super fast, easy with amazing communication!
I was able to get my GTS coding done today as well as a NBTEVO5-6 upgrade. Let me preface this by saying the car was in for a fresh alignment (hit a few holes/bumps on the highway, thanks PA roads) this morning prior to the coding and I was able to drive it a good 30-40 minutes prior to the coding and after fresh alignment. This was done so I had a good before and after comparison with no other factors. I have a non-zcp F80 with M-performance suspension (set slightly below recommended height) and no other suspension work. Its on 19x11/19x9.5 wheels with almost brand new MPS4S 265/35 and 305/30 tires just for reference. The coding options I got were GTS steering, GTS diff, Euro GTS MDM and CS EDC. I also already had the GTS DCT via BM3. My initial impressions for each piece after a 30min spirited drive. GTS steering: this is a massive upgrade in all categories, it is tighter, more responsive and there is less play in the steering wheel. It is still not anywhere near the non-electric power steering feel but it is much better. Car does not feel twitchy and is very direct with input. GTS diff/Euro MDM: another pair of awesome upgrades, the diff no longer seems as confused about what is happening in terms of driver input and feels like it is more in tune with the transmission. The car is also no longer has as much wiggle to it when traction breaks and is better at maintaining a straight line. It also feels more predictable. Euro MDM feels is as expected and previously discussed with having an increased time before intervening. CS EDC: This option I am still feeling out. Initially the car feels slightly softer in comfort but did not feel unstable. I will be fair in saying I was not taking any high speed turns to fully test it in comfort mode. In sport I did notice that the ride felt slightly stiffer especially in terms of rebound but it did not feel uncomfortable. Everything tightened up even further in sport+. The dampening change was most noticeable. This again was a tough one to put into words but I will test it for the coming week and see whether I decided to stick with it. 9M71 I would recommend giving it a shot and seeing how the car feels with it. I will update this in the coming week after driving a bit more and feeling out the changes. |

+1 Another happy customer - I can't recommend kubax86 enough! He fixed the mess that Thor left behind. Night and day difference in steering and differential engagement.

I flashed my car with the Thor GTS MDM, differential and steering, while I feel no difference in the steering I did notice a difference in the MDM not kicking in as before, my question has anyone reflashed with kubix and noticed a difference with the GTS MDM?

Steering: MUCH better than OEM. As someone mentioned above, this was the first thing I noticed as soon as I pulled the car out of the garage after the flash. It now feels like a proper power assist setup: at low speeds (parking lots, etc) the wheel is FAR easier to turn, but at higher speeds, it does stiffen up a bit (but not too much like OEM was). I prefer my steering to be very light, so I drive exclusively in Comfort. I can't really comment on GTS Sport/Sport+ steering b/c I don't really care for anything heavier than Comfort so I never use those settings. LSD: Much better than OEM, but similar to Thor/F87. The car definitely hooks up better in a straight line, and if it does break loose, you can stay on the power without it cutting out and killing your momentum. This was the one thing that didn't change/improve much with Kubax's flash (but that's okay b/c apparently the F87 that Thor installed was still much better than OEM). AlteredBe4st , this is for you... GTS MDM: Much less restrictive than American/OEM, but a bit more restrictive than Thor/Euro. American/OEM MDM is a complete joke. It doesn't allow much slip angle whatsoever (not much better than DSC fully on). By contrast, the Euro MDM that Thor installed, allowed way too much slip angle. Tbh, I'd have to lift before it ever kicked-in b/c I was afraid the rear end could continue to come around, and I feared it wouldn't ever save me before I got into trouble. It pretty much felt like DSC fully off. The new GTS MDM is perfect. It's right in the middle between boring American/OEM and insanely loose Euro. It allows the back end to come around, but it does catch you at a reasonable point of slip. It feels much more like Porsche's PSM (which is about as good as traction control can get). Edit: I forgot to mention just how cool Kubax was/is to work with. I won't drag you through all the details, but summarize, I have a Mac and didn't have the appropriate Windows software installed to get Kubax's process going as smoothly as it usually does. Rather than telling me it simply wouldn't work on my computer, he actually spent lots of extra time working with me over two different 45 minute sessions (remotely tinkered with my settings, etc) to get it all done. So even more props to Kubax, not just a great product, but also for lots of patience and going the extra mile to get the flash done despite technical challenges.

Just used Kubax86 services today.
I have not used any type of previous flash and I just had the GTS flash along with some miscellaneous coding done today which was based off of this thread. I wanted nothing on the motor touched. Been there, done that past platform… For the GTS coding, my first thoughts: What a huge difference. The best part for me is the CS damper coding. It’s way more compliant. Those damn lane reflectors no longer fell like I’m hitting a small animal on the road. Sport feels better than the old comfort mode and comfort mode is actually, comfortable… Sport plus is still nice and stiff The DCT: beyond better. It doesn’t lag or “think” with light throttle input Diff: Lays down power without much wheel spin. Much better Steering: Improved. If anything I felt it made the steering much softer and not the other way around. But also, in a good way. It steered like a ride on mower before. Too heavy MDM: Haven’t played with it enough yet. As for the coding goes, I have a late model and a lot of it doesn’t work on the later cars.I was so disappointed to not have seat/easy access. However, I didn’t like having no active sound and he coded that back in as well as removing the rear view camera at all speeds.(it wouldn’t turn off after reversing then putting in D) Very very happy overall and the car is no longer twitchy and strung out. Thanks Bimmer-remote! |
