Default 335is launch control update. 135is TCU 3,500 RPM launch works - 11-08-2015, 10:52 AM

Hey guys. Just a quick update on the 335is DCT launch control. Credit for this goes to @BMWJunkie who came up with the idea and was the first to test real world. Also thanks to @FL335 who helped me get my laptop set up for coding.

Anyone with the 335i/335is/Z4 DCT knows that the launch control is fixed at 5,000 RPM. This can't be adjusted like the M-DCT cars. Also, the 135i/135is oddly had a 3,500 fixed RPM launch control that could also not be adjusted. The thought was to try and get the 335is working with the 135is DCT flash, thereby giving us a lower LC RPM to try out.

@BMWJunkie was able to get the latest TCU ZB for the 135is and the 335is. Apparently they are very similar but we know they differ in LC RPMs. He flashed the 135is TCU file to his 335is. That resulted in a LC of 3,500 RPM on the 335is! He did it through his shop but said it should also be possible via WinKFP and INPA/Dcan cable, similar to how you would do an Alpina flash. I followed the Alpina flash instructions and chose the correct ZB for the 135is. Total process took less than 5 minutes. Sure enough it worked and the LC RPM is capped at 3,500. While this isn’t full control it is the first time we have been able to manipulate the LC value on the 335is. While 5,000 may still be best for a sticky track/slicks, 3,500 should be much more tolerable in other situations, especially for guys who may want to try it on street tires, etc. I’ve put about 40 miles or so on the car and the transmission seems to be behaving normal with firm and fast shifts.

The Alpina flash process is pretty well documented on various forums/youtube so I wont cover that here. Make sure you have the recent Daten files as this is the newest ZB available. The ZB is found in GS40 (instead of GKE215 with the Alpina). The 135is TCU ZB you will choose is 8606072. This has only been tested on a 335is but I suspect it will work for 335i and Z4 DCT cars as well. Try at your own risk!

First time the launch RPM has been changed for 335is. I'd call that pretty new

sry i dont read all. but now i do
8606072 isnt 135is its 135i Software. so you change your IS Software to none IS.

I was told it was 135is but not sure if even matters since the launch RPM is the same for 135i DCT. The IS tuning changes are in the DME software. This is just the TCU.

335i DCT Software is not same like 335is DCT Software, so its not just the DME
your software is now from 135i N55

Considering no one has mapped out the TCU software you don't have clue is what is the same and what is different. if you have the 135is ZB do share. I'll be glad to try it. What we do know is that there is a difference in launch control RPM in the 1-series DCT and 3-series DCT. That is what is being tested here. Otherwise the transmission functions normal.

That is the 335is ZB that was on BMWJunkies 2013 335is. He also confirmed that the 2013 135is DCT does use 8606072. Prior to that it was 8606070. Not sure where you are sourcing your info.

sry, think you asked about 335is not about 135is.
135is dont have DCT, only MT or AT

Seems to be some confusion here.

The 135is does have DCT and uses 8606072 as its latest TCU ZB.
335is has DCT and uses 8606074 as its latest TCU ZB.
I am using the 135is 8606072 ZB on my 335is because the 135is TCU has 3,500 RPM launch control limit instead of 5,000 RPM that the 335is has.

Yes I think you're confused or have wrong information
the 135is came with N54 Engine and with AT or MT not with DCT, so you cant have 135is N54 DCT Software, you have 135i N55 DCT Software.

This is for US production cars.

I found the little bmwarchive.org site you are getting your info from. Sadly it is wrong. It says the US had a 135is from 11/2006 to 2/2010. We had a 135i but the 135is did not surface until 2013, with the N55 engine and MT or DCT trans option.

You're confusing the Euro market models with the NA models. The 335is was the only 3 series offered with the DCT and N54 in the US and were produced 2011-2013. The 135is was a one year only offering in 2013 with a N55 and
DCT. We are referring to the US model TCU software and what we know works here. Now I'm sure there's overlap in ZB #'s between the two markets but our DCT exposure was very limited here.

Musc,

any update on how this has been running since you flashed the car? any better or worse?

also what would be the correct ZB to make the same change to an EURO N54 with DCT?

follow the alpine flash process right?

thanks in advance...

I'd also like to know. Some JB4 logs would be even better!

Guys,

any idea what the hardware part numbers are on 135is and 335is cars in INPA???



The above is mine

The hardware # for either the latest 335is or 135is flash is 8606066 which will correspond to both their ZUSB #'s. Your hardware # and ZUSB #(7622028) are both very old versions of the GS40 software.

Just flash the bloody thing mate!

Where is a good tutorial that will walk me through loading the 135is DCT software on my E89 Z4? I have looked/tried with WinFPK but am not having much luck.

Watch an alpina flash tutorial on youtube.

Make sure you have screenshots of the 2 screens above so you know your hardware and ZB numbers before you begin. In case you need help getting back.

Make sure you have the right settings in the WinFPK ini settings.

The post by RSL on bimmermoost title 'Module flashing stuff' really helped me out.
I disabled the UIF writes to not reduce the write counter by 1 as well.

1) Make sure your WinKFP is configured correctly. If you have any of the UIF boxes checked, you can uncheck them. This will keep you from having to enter the VIN and the flash being counted against the number of flashes allowed. Hook up cable, load WinKFP, turn on car power but don't start. You can load INPA first if you want to make sure you
have a connection just be sure to close it before starting WinKFP.

2) Press F1 Comfort Mode

3) Press F3 Update ZSUB

4) In the ECU family, choose GS40, then OK

5) Press F2 Choose ZSUB

6) In the ECU family again choose GS40 and the ZB number field will
populate. You're looking for 8606072 which is the 135is ZB #. Find it,
click on it, then click OK. If done correctly the field at the top will
populate with the Assembly ID # which is the ZB# of the flash and a
Hardware #. Click F8 Done. If your UIF boxes are checked it will require
you to enter your full VIN before clicking Done.

7) Press F3 Program. There may be a popup, can't remember for sure off
the top of my head. If you entered your VIN it will tell how many more
times the ECU can be flashed.

8) Flashing begins. It will go to 100% twice, first very quickly, then the
second time will take 2-3 minutes. When done you will get a popup
saying programming done. Click OK, shut off car, remove key, lock up
car, wait 5 minutes, then start the car. You should be good to go. Check
for codes, you may have a few, I always do. Clear them with your tool
of choice. If you have the ability to reset the trans adaptions I'd do that as well

9) It's easily reversible. I would suggest doing a UIF read with INPA and
prt scr to save your original ZB #'s if you want to go back to stock or
even better is use 8606074, which is the latest 335is factory TCU flash.
I don't think it would make a difference for you. What I was doing was flashing the 135is tranny flash only for the 3500 rpm Launch Control it has. If you were just updated
