Discussion about issues encountered whilst converting to M3 Flash and GWS

[Bimaxtremeretro]

Guys here is why I don't think the m3 dsc is a requirement. Even with standard coding and msd80 + 6hp auto, it's fully functional with the exception of active cruise control which has an additional LDM module (not the one in the dsc unit).

That ldm module is very old and was fitted to all 6cyl cars for the braking function pre mid 2006 or some think like that. After lay 06 the ldm was built into the dsc module with the exception of active cruise. If you had active cruise this module is needed regardless of dsc, so far as I know. This ldm needs to be modified to suit the m3 dsc unit for msd80, I'm not sure this is something I will embark on as it's a limited opportunity I believe.

So the the theory is simple, if an m3 dsc unit works perfectly on n54 6at, it sure as shit will work on the dct.

If you look carefully behind the cas, this is the extra LDM for active cruise only or pre mid 06 dsc modules, that's where is lives.

Some version numbers for all to see.
You will also notice this setup has the m3 szl for mdm in place, not the active cruise stalk, and it's still not complaining.

Hopefully that helps you guys figure some answers out.

I'm on the fence about trying to fix the wheel torque error in the LDM, just not sure if it's worth it for this setup and I doubt anyone globally has a solution.

Do we know where Derrick is at which his

Guys there is also 1 other very important bit of info which I forgot to mention.

When playing with the cruise VO there is an option in the dmes adaptations which is variants reset. Under inpa adaptations under adaptations, it's option F8. After this is reset the cat needs to go to sleep mode. You can also do it in tool32and needs to be done when some changes are made to take affect.

I can't do the adaptions for pv1 and pv2 it complains about the integration level 520 and how this adaption isn't available on it.

All other adaptions worked but I haven't drove it yet.

Parts are inbound for me. I'm looking to validate the Kombi/GSW only combo, but for the N55 E82 platform. I will have to do a bit of homework on R270 usage and nettodat changes for the Kombi. Do you guys think running with different VIN and mileage would be fine for setting up and testing initially? Or would it be best to reset the Kombi prior to even starting?

You might need to try with tool32 and connnect to the module ditectly. Use ncs to connect to the module and it will give you the relevant number to connect with tool32, then just go through the options and it will all be there.

Best to change the vin for the kombi. There are workarounds but it's a pain in the arse.

Okay, I'll wait for the programmer and test harness. Looks pretty basic, besides getting the needles back on in the exact spot.

I haven't found the needles to be much of a problem. At least for the 5 series, don't know if it is the same.

They all go to miminum with no power so you judj put them back on at minimum.

Personally I'm very fussy.
Mounting the needles close to the exact spot is possible but mounting them to the exact spot I think is impossible.

So the trick...

Change the chip and do what you need to.

Then put the cluster on without the housing. Use inpa to individually move each needle to where it needs to be. E.g. tell inpa fuel = 50% , then manually move needle to 50% if it's out by hand.

Easy as that.

Not sure I'm seisee what your talking about. I went into the dkg module. But couldn't find the options to do those adaptions.

Also after driving it with resetting all the other adaptions it still sucks. If anything it got worse.

They are there. Did you go in under dme and clear the variants adaptations also ? That's important.

Allot of this is trial and error until it works. It's was never really intended to be used friendly or easy as such, which in turn makes it rather frustration bit worth it in the end when it all works.

Sry guys. I had to head to Boston for the week for work. I’m back and will dig in some more. But read this thread:

https://bmw.spoolstreet.com/threads/help-transmission-coding-related-issues.3143/#post-37977

 

[dyezak]

The interesting thing in that thread is that it was a ZF6HP (6AT) having issues shifting, not having DS mode, and having control issues. Root cause appears to be a jacked up clock spring.

If a broken clock spring is causing a 6AT to have shifting/drivability issues and losing a mode (DS) all together that tells me the clock spring has a significant role to play in transmission functionality.

I think that's why @Bimaxtremeretro got it right the first time. These modules are designed to work together, and he swapped all the modules at once.

I'm thinking we have obviously figured out that the M3 flash won't operate at all without the M3 GWS. Because the GWS sends different control signals out. And based on the thread in the previous post I'm wondering if something is missing between the GWS and SZL that the M3 flash needs. BUT, based on my experience with the DSC module we know the SZL and DSC pair up during flashing/coding....so I'm not sure if the SZL would work without the DSC.

So to me it seems to indicate that the GWS has interaction with the SZL and the SZL has interaction with the DSC. So changing all the modules is the only option just like @Bimaxtremeretro did.

Great points here. I am a bit sad because of the hopes of a simple GWS swap... As time goes on it seems like you and @Bimaxtremeretro are correct with needing all pieces to the puzzle!

There was some hope that adaptation learning would solve the issue but there must be some code expecting certain modules to exist. What I find weird is that no codes are thrown at all, instead the car acts strange. Why not throw a code for missing messages on the bus?

 

[doublespaces]

Now the quest to see if the SZL can be coded without the DSC and what impacts that would have if so.

 

[aus335iguy]

That’s what I’m thinking too. It could be that the Szl is the only piece we need rather than all of them. Weired though that Szls aren’t gearbox specific just rain sensor etc specific. More to explore I suppose. Failing this... final drive needs to change.

These are the adaption values from the transmission before and after teach in, i wonder if i flash back to the 335is flash if it will have different data, specifically of interest to me is the gearset variant. I think you can input these values manually for replacing the dct module so possibly open to modification.

previous transmission adaptions
Amplitude factor TIN_AMP_0: 1.09
Amplitude factor TIN_AMP_1: 1.10
Amplitude factor TIN_AMP_2: 1.11
Amplitude factor TIN_AMP_3: 1.06
Characteristic curve offset TIN_P0: 0.03
Characteristic curve offset TIN_P1: -0.24
Characteristic curve offset TIN_P2: -0.19
Characteristic curve offset TIN_P3: -0.11

Taught-in values of transmission adaptation:
Amplitude factor TIN_AMP_0: 1.09
Amplitude factor TIN_AMP_1: 1.11
Amplitude factor TIN_AMP_2: 1.10
Amplitude factor TIN_AMP_3: 1.05
Characteristic curve offset TIN_P0: 0.08
Characteristic curve offset TIN_P1: -0.27
Characteristic curve offset TIN_P2: -0.16
Characteristic curve offset TIN_P3: -0.08



Please note down the following transmission data:
Transmission code 1: 48

Transmission code 6: 49

Next: other data.
Please note down the following transmission data:

That is interesting.
