DIY: Flashing your SMG module with CSL Software + CSL Rev Matching and Torque Maps

[sd561]

Hi all, would appreciate some guidance - after several months of prep and planning, i am finally ready to flash the ECU and SMG module.

Everything has been smooth sailing for the most part, although hit a wall a moment ago in WinKFP (Version 5.3.1)


Everything looked perfect (attached screenshot showing so) right up until i hit Program, when i got the following error (also attached)


Any ideas? The only deviation I took from Martyn's instructions was that i sourced different E46 Daten files (from NCSExpert, V73 2024/10 Version) - but beyond that, followed all steps to a T.

By my account there were no issues with preparing WinKFP prior to attempting programming, all files and folders were copied/pasted in their respective places and everything looked ok.

What did i do wrong?

EDIT: port was set to COM3 in windows, changed to COM1 and resolved. First impression: WOW

Has anyone experience the following?

I have a 2005 ZCP SMG and have converted drivetrain to CSL (airbox, oem snorkel, MAP sensor, CSL tune, Martyn tool, etc).

Now when driving in S4, the upshifts are OK, downshift blips are great (when shifting +3500). Blip matches revs and there is no engine breaking (actually blip slightly over revs).

In S5, the upshifts are great (a little clunky, but that's expected), but the downshifts unsettle the car. When I blip (again +3500), the rev match is horrible. It's like the car needs to blip 1000rpms to fully match, and it blips 600rps and engine brakes the remaining 400rpms... the car becomes totally unsettled and quite dangerous.

I would imagine this isn't supposed to happen. Can any-one take a look at my SMG tune? I got it back in 2010, so i don't remember who did it but I can't imagine BMW OK'ing something like this.

If this IS the correct tune from BMW, is there anyway someone can adjust S5 and S6 rev matching?

I don't experience what you do.

What gear does your car start in? If you have the CSL tune it will start in A3 every time. Regardless I would flash using these instructions.

This option increases the clamping force of the clutch reducing SMG ‘clutch slur’. It is recommended when using the CSL SMG Shifting and Rev Matching option.

Thank you.

What does the "SMG inertia update" do?

Thanks for saving this.

Can anyone confirm that the Engine Torque Maps change here is the "SMG inertia update" referred to elsewhere?

I followed the TCU flash steps with WinKFP and as some people described it took about 30 seconds and I did not get to the second faster run. Do we have any info on what might be the cause for this? I feel like something got missed in the process.

EDIT: Well, it worked - the car defaults to auto mode and the shifts are as they should be.

[E46m3zcp]

Great. At step 3 right after setting up WinKFP, when entering the Comfort mode and the "ZUSB" I get different options than in the screenshot for "integration". Any idea what this is? According to Google Translate "Unverbaut" from the original screenshot means unobstructed, if that matters :-)



If I move on to the next step, after clicking "done" the contents of the main screen are identical to the screenshot in the original post.

EDIT: After closing and re-opening WinKFP, I get identical screens as in the original post.

Is this different than TTFS or Build Journal tunes?

I would assume that they are not different. It can easily be checked by looking at the calibration maps and comparing them to the factory CSL. I would 100% stick to the factory CSL calibration for the SMG system.

I have compared a few of these small tuner engine calibrations to the factory CSL. In certain cases, the changes made to the maps were either minimal or very questionable.

CSL Rev Matching is for me to dangerous.. i do this now automatically with ecuworx for 20 pounds

Thank you.. I can see 2x 12V and 1xGND but not the signal to the OBD.

Can I change the DME with ecuworx software or better manuel like a post 1?

Both should result in the same thing, but the ecuworx tool is a black box, so can't validate.

Hello,
I want to perform the whole operation on the bench station. Does anyone have the pinout for the EGS control unit? And is it absolutely necessary to adjust the DME as well? What happens if you only modify the EGS?

Straight from TIS (so trust with same amount of trust you would use for other TIS data):
