And I didn’t think about the adaptive dampers carrying over in the F087GTS coding. Good point! I’ll try the F087CS coding from the M2C and see if it provides enough slip. Mostly what I’m trying to accomplish is to have Comfort like steering and throttle response while on track, which means running MDM mode on the OG M2 and hopefully not too much intervention with F087CS coding. I’m comfortable running DSC completely off, but the Sport style steering & throttle that comes with it makes the car more responsive/jerky than needed at the limit. |

If I had enjoyed my times in M2C's and M3/4's a bit more (I've driven all of them quite a bit on both the street & track), I'd make the jump. Plus, all the work I've done with tuning, cooling, brakes, suspension, etc would need to be repeated, albeit less effort and cost would be needed--but I'd pay for it via additional depreciation, taxes, etc, by trading to something newer. Also, I've learned a lot going thru the upgrade process on my M2, so I'm emotionally invested and not ready to let her go yet. I'll do this last round of engine & cooling upgrades (HPFP, E45-50 tune, Evo 3 Comp), and call it good and drive her for a few years. So, I'll wait for the next gen M2 (or whatever other cars are interesting at that time)--let's just hope it looks good. Anyways, back to coding discussion! |

Having spent more time with the GHAS coding now though, it is a slightly different kettle of fish - and has two stages: 1) on OEM suspension: the effect is fun, but does make the rear end seem quite aggressive in the way it delivers power in very quick changes of direction (E.g around sharp S bends) - to some, this will be unsettling. 2) on coilovers: I have been lucky enough to get hold of some AST 5100 coilovers, which I fitted last weekend - with these on, there is no issue at all with the GTS GHAS - the brilliant AST dampers have sorted the above feeling completely - it feels absolutely MEGA!!!!! |

Either the GHAS module has changed (and older ones don't support the newer code), or both car models are using the same code set/configuration for the GHAS module. (I suspect the later personally) |

I’ve been reading through this thread and still confused about how to do this?
Can someone explain in a nutshell how to code GTS steering to an M2C?

First you need ESYS, I suggest reading up on it before getting into coding. Then with ESYS you make the changes in the module.

1) Software: https://www.bimmerfest.com/forums/sh...d.php?t=983244 2) Guide: https://www.bimmerfest.com/forums/sh...d.php?t=983245 I just didn't post it earlier since I am not sure if I can post links to other forums, if it is not allowed I apologize and just let me know and I will remove it. Note, despite the fact that the software is available in #1 you will need a launcher to FDL code, the issue is that this is not free and can cost you up to $200. There are free options such as the launcher rearm to rearm the free versions of the launcher, however it did not work for me and would give me error C157. If the rearm doesn't work for you then you have to pay for a licence, in which case talk to shawnsheridan and he can link you to someone who can get you said launcher.

On an OG / non-Comp car, disabling traction control (DSC long press) puts your steering (and throttle) into "Sport" mode. (FWIW, there is no "Sport+" steering mode -- per BMW's documentation, "Sport+" drive mode switch just uses "Sport" steering. We have "Sport" and "Comfort" and that's it for steering options.)

There are 4 x distinct steering modes on the car: - Comfort - Sport - Sport+ (the difference to Sport is small admittedly, but noticeable) - DSC disabled (not to be confused with Traction mode that uses Comfort steering) It may be on the earlier ISTEPs that the differences were less pronounced, so not noticeable, but on the later versions it's as above. |

thanks for you fdl coding guide. i applicate it yesterday onmy m2 comp ece.
egs, dsc, eps and ghas works very great, but since the other swfl / swfk are flashed to the egs, i miss my gear display in my kombi cluster instrument. i-step 20-07 ;-) anybody knows how to fix this? thanks in advance |

Thanks widetyres for this informative thread. Could you please explain why the M4 GTS MDM/Differential coding can't be used on the M2 Competition and is there a way around to make it work?
I've also installed a set of AST 5100 coilovers plus sway bars on my car, and ever since then the differential has been feeling quite lazy or unresponsive. It definitely pulled harder out of the corners when it was on stock suspension, where I originally thought the ELSD was more actively sorting out the roll from the soft springs. However, now that the car is well planted and tight through the corners it doesn't seem to be putting down the power as well and I'm only getting marginally better lap times. Some people were saying that the ELSD isn't calibrated for the suspension upgrade which is what led me to your post, since the M4 GTS is a more hardcore platform with a dedicated track suspension. Also I'm wondering is there any difference in the DSC OFF mode for across all the variations of the models. Since even though I track with DSC OFF, I still feel that there is something working in the background at times and from what I've been told the driving aids are never completely 100% off. Your input would be greatly appreciated. Thanks! |

Further to that post, the M2CS Racing option (F087GTS) should now be available to you (if you have a new enough ISTEP), which is the option I would go for (over M4GTS) - I haven't tried this yet as I need to update my car, but many have. Quote:
How have you got yours setup? - I think that what you are feeling is more down to that than the ELSD. It took a while, but I settled on the rear needing to be 2-clicks harder than the fronts. I think I am currently at F7:R5 clicks (from full stiff), but TBH it doesn't matter how many clicks you are running, it is the 2-click differential front to rear that is the important point, as that helps shift some weight to the front to aid turn in grip. Running the above clicks, with GTS coded GHAS & DSC gives exceptional drive into/out of the corners and the car can yaw on throttle input alone. TBH, IMO the stock suspension doesn't have the grip to run the GTS GHAS as the rear becomes way too keen to oversteer - the AST sorts out the balance nicely. Quote:

I actually did have it with a 2-click differential, F -2 and R -4 from full stiff but I found the car still understeered a little so I went to F -3 and R -4 where the car feels more neutral on turn in. It seems like the car isn't really yawing as much as it did on the stock suspension and the throttle modulation is not as reactive. There was a time where I was mid corner applying throttle to rotate the car but nothing really happened until I exited the corner and all of a sudden the wheels started spinning and the car went sideways. I was just thinking with the M4 GTS flash maybe the threshold parameters would be higher overall across all the driving electronics since the car would think it is a GTS car. |

You have the click difference the wrong way round - I did the same at first given that they are sold as rebound adjustment only. However, I spoke with a racer friend who said that they would definitively be doing compression as well. Knowing that I flipped the clicks difference and it was an amazing result. It might seem weird to think of it that way, but run the fronts 2 clicks softer than the rears and you won't have any understeer at all and can run the suspension a bit softer all around but still have great turn in. Well worth a go. Hope it works for you. |

Interesting, I will definitely try that for the next track day. Initially I started with full stiff all around and found the car a little twitchy, which is why I softened the rear to get it less tail happy. Thanks again for the tip! |

I think it would void the warranty. I have seen people mention that bmw dealers charged them to put the car back to stock before doing other work. |

Coding doesn't seem to be a problem; flashing an ECU likely would. Coding is purely a software change (you're changing one parameter for another, the car might just think it's European suddenly); flashing is a firmware change to allow for new software, and the car would probably recognize that something about that is different. |
