Can we make the first rule of tuning, CONFIRM YOUR HARDWARE!!!!!
That means running, test drives fuel trims whatever on stock or base files...

I made a point to confirm the health and proper functioning of my hardware for months before writing anything non-stock to my ecu.
I logged using me7logger and recorded multiple instances which I then reviewed using ecux_plot to root out any possible faults or issues and to ensure proper overall functioning of my vehicles primary components...
 
My hardware is on point.

what did I miss about launch control? I thought I did a good job?

I am aware of most of the parameters in my .bin and what their functions are. I refer to the s4 wiki every day and I have a copy of it printed and binded that rests on my lap whenever I'm working on remapping and so forth. I also attached another pdf that I have printed out that I also refer to on a daily basis. I am very willing to learn and I am just trying to get some help. Thats why I posted in the noob section of nefmoto... Also the file I posted isn't the same as the file your referring to. I have a lot of various .bin files on my computer which I often refer to as a reference which help me learn. I am not looking to discredit anyone or do anything wrong.

Do you care to tell me what I've missed in regards to implementing launch control in my .bin?

Or do you atleast wish to tell me why, in your opinion, you say I have not properly implemented launch control in my file?

i looked at this briefly before leaving and now back looking at it. i was concentrated on particular maps before looking at exact changes (in particular maps).
you have a soft launch enabled.

that file would not make you car smell like raw fuel.

ha ha ha very funny...  Cheesy

As you know from my previous thread you referred to earlier, my car has been sitting for a few days. Could the excessive fuel smell be caused by the car sitting for a few days and then starting it up? I turned the car off roughly 15 seconds after starting it to avoid any chance of damage and I decided I would wait for clarification from fellow nefmoto members... Thank you for clearing this up for me. So in your opinion I should be safe allowing my car to idle a little bit longer to see if the smell continues?

Thanks for continuing to help me @k0mpresd

Also when I start me7logger something weird happens. Here is my usual (unusual) procedure:

Open me7logger
turn key to on position
click start logging
command prompt opens and says failed to connect
open nefmoto and connect slow init
once connected in nefmoto, click disconnect
close nefmoto and toggle back to me7logger
clock start logging
command prompt opens and connection is successful
I then start car and engine shuts off in 1 second
check DTCs in VCDS and there is 1 code "engine start blocked by immobilizer"
clear codes
open nefmoto and connect
click disconnect
close nefmoto and toggle back to me7logger
clock start logging
command prompt opens and connection is successful
turn key and start car
at this point the engine stays running and logging continues
...

any ideas how to prevent this without disabling immo?

Start the car, pull the cluster fuse so it dies but the car will stay running.  The cluster often causes interference with ME7Logger.  I've cut my cluster with my front fog switch.  Pull out to log.

What maps have you modified?  Why did you do this?  What hardware do you have?  Changed MAF, injectors?  If so, what did you change to accompany this?  Had a smoke test?  Why have you attempted to implement LC?  Basics first.

Post up a list of maps you've changed, what you've changed them to - and YOUR reasoning for this; not the internet's.  Tell us why you changed it so you've got a solid understanding.

Who's file have you copied?

there are decimal points in that file that are exactly specific to files i have released, though albeit parts of it are drastically changed and left out. but it originally started life as mine. the other file he posted was a lot closer match, still tweaked in some areas though.

WWW

you only copied certain changes because you weren't sure what all the patches were and why they were important.

This is a GOOD thing, not a bad thing.

It should be encouraged.

That said, I don't think anybody should be copying any LC routines unless they know exactly what they do.

Just my opinion.

Before I change any maps in a .bin I always refer back to the s4 wiki or the pdf "understanding ECU remapping the audi TT 1.8t variants" (which actually refers back to the s4 wiki quite a bit lol). I will only begin to alter a parameter once I understand what the purpose and function of the particular map is. I have downloaded and acquired roughly a hundred .bins and .xdf files from many different sources over the past 7 months or so... Many tuned files, original files, Almost all of them go unused but they dont take up too much space and they have all been wonderful learning tools that I have used in numerous ways to further educate myself. I often times move between parameters comparing graphs and tables, both to learn and also to verify my own work with others... I've cross-referenced tuned files with their originals and made tables in excell that tally, compare & contrast the parameters that individuals altered. From there I export the list of maps which were altered and I place that list into microsoft one note. I then placed a backslash next to each parameter-name representing each time I found that a specific parameter was altered. After going through roughly 20 tuned .bin files (from both amateurs and professionals) I printed the list with all of the backslashes on it and created a color categorized system using a yellow, blue and orange highlighter. Yellow was the highest number of times a particular map was altered in the 20 bins I reviewed, orange was the second highest and blue was the least amount of times a particular change was noticed across the 20 bins. Now I had a rough idea of which maps were most significant (these would be parameters that we're likely a requirement to achieve a quality stage 1 tune), secondly, orange, would likely contain maps that were more of a personal preference if you will, some of these might be parameters you would find in a stage 2 file... Long story short, from there I took everything I had just done, the excel file, the one note file... I printed all of it and also included the highlighter color coded system I just mentioned. I printed the s4 wiki and the other pdf I mentioned and all together I have about 100 pages of reading material that is so nice and convenient to have in paper form. I am a graphic designer too, mostly digital and web based but I do a bit of print stuff too... I put together a nice cover in photoshop and I put everything together. My cover, s4 wiki, remapping.pdf and finally my notes (I also included 10 blank pages, 2 in the front, 4 after the s4 wiki and 4 more in the back all for notes and so forth..)

Heres a picture.



Thank you for all of the help everyone. I appreciate it and once I have logs I will make a new thread in the datalogging or rate my logs section so that I can continue to build on this wonderful community by contribute my material for others to benefit from in some way or another as I have benefited greatly from those before me.

Just my opinion.

I read through the entire thread on here started by @nosbeui on implementing launch control.
Once I had done some research I followed the guide and performed the necessary procedures to implement LC.

Original thread: http://nefariousmotorsports.com/forum/index.php?topic=151.0


So you want to launch like the cool Subaru/Evo kids? As it turns out we can! And it's pretty easy. It works like this.. ME7 has a bulit in raised rev limit function which is unused by default. We set it up so the standard rev limit (NMAX) becomes the launch rpm and the raised limit becomes the normal limiter. It's controlled by VNMX so that as long as the car is below 1.25 km/h the launch control limit is used. Above 1.25 km/h the raised limit aka the new normal limit is used.

Here are the maps I modify including their M-Box addresses

CWNMAXMD (8-bit) Codeword Drehzahlbegrenzung Set to 1

VNMX             (1157E)     The vehicle speed for activating the raised (normal) rev limit. We set this as low at it goes (1.25 km/h) so the launch control shuts off as soon as you start moving off the line.
DNMAXH         (16304)     This is the RPM above rev limit when the fuel cut comes on. Tweaking this helps make more boost on the limiter. I use 50 RPM  (Keep in mind the maximum RPM limit is NMAXOG + DNMAXH)     
ITNMXH          (16308)     Dwell time under lower limit before activating the upper limit. We set this to 0 seconds
NMAX             (1630A)     Ends up being the launch RPM. I've found 4500 RPM works well.
NMAXOG         (16312)     This is the raised RPM limit which becomes the standard limit. Mine is set at 7100 RPM
TMOTNMX       (16316)     Coolant temp for activating raised (normal) rev limit. We set this at -48 so that it can activate at any coolant temp.
TNMXH           (1631A)     This is the time duration of the raised (normal) rev limit. We set this at it's maximum value of 655.3500 seconds. I haven't had a problem yet with this and have been testing for months.

And here are the results! http://vimeo.com/14266421

Eventually the plan might be to make this into a self installing patch file like the Subaru guys use.

I just uploaded a Stock M-box with this code http://nefariousmotorsports.com/forum/index.php?topic=152.0

Additional IMPORTANT Info!

Be aware that when using this method of launch control there is a time limit of 10.9 minutes for driving above the launch RPM. Therefore I suggest you set this appropriately high, somewhere above your normal cruising range. After 10.9 minutes the throttle shuts off until the RPM falls below the launch RPM... This is a potentially hazardous condition so please be aware and implement this code at your own risk!

Additional additional info

Thanks to k0mpresd I've learned certain ECU's need the map CWNMAXMD (8-bit) Codeword Drehzahlbegrenzung (Codeword for RPM limiter) changed from 0 to 1

-Brandon

EDIT: Correction the map is DNMAXH not DNMAX

That one^

That book looks cool. Maybe my favorite thing about this site, is how much different some of us look at cars.
I can tell most of you come from a computer background, where I know nothing about any of that I know the
cars. Its very strange to try and look at it from another point of view.

Thats not actually real LC, just toying with the RPM limiter... i thought you were referring to the LC/NLS ASM hacks.
