Official F10 Coding thread---Exploring Your F10

Tach in the HUD would be wonderful. Any festers in Nor-Cal?

Excuse my crappy soldering skills. Here's some pictures of the OBD2 side of the ENET cable.

The cable in the picture is CAT6. For a better reference to the schematic, the following applies:

PIN 3 - Light Blue (CAT 6) would be Green Stripe (CAT5e)
PIN 4 & 5 (Bridged) - Brown (CAT 6) would be Brown (CAT5e) - This is what is grounded to the RJ-45
PIN 11 - Green (CAT6) would be Solid Green (CAT5e)
PIN 12 - White (CAT 6) would be Orange Stripe (CAT5e)
PIN 13 - Orange (CAT 6) would be Solid Orange (CAT5e)
PIN 8 and 16 (Bridged) with a 510ohm, 1/4 (.25) watt resistor

I'm in ny and would love to meet and have some of these tweaks. I must say I love this forum......

Fort Lee, NJ resident here...

This is big... Bigger than leveling up in "Contra" lol. Very interested in meeting and hopefully learning how to do this and sharing the knowledge. It all looks foreign to me so far though.

I have an F13. Hope it's the same coding as the F10.

hd750li,
No problem at all..,. But please keep us posted if you guys find any new tweaks

I found this, http://www.obdexpert.de/codieren/index.php

Updated post #1 with few details .. Will add the excel sheet (With the help of Shawn) with all the module names and valid values for all the options that can be programmed

@hans_gregor; Nice find! Thanks for the link.

@DreamCar; PM me your email address, and I will send you the Spreadsheet.

Ok. Since I am HUDless, can someone with both the HUD and Active Cruise Control advise on:

1) What is the HUD Start-Up Screen? Is it another Disclaimer Screen?
2) Does the iBrake Distance appear in the HUD?

Shawn,

If i am not wrong the HUD startup screen is not a disclaimer... When we start the car we can see a Nice BMW logo with red lines beneath the logo... I would bet 60% of the people wouldnt even notice this, it only stays for few seconds but looks very nice i wouldnt disable it

Like below
(got it from Stealth.pilots thread)

CAS TC_MSA_MEMORY is confirmed to keep auto start/stop on or off through ignition cycles on my 01/2012 build F10 N55.

Thank you guys very much for spotting this, the biggest gripe I had with this car is now gone...

Now to enable this same functionality for Sport and Sport+ modes, defaulting to Comfort mode is a little annoying.

To those that have built their own cable - do you feel it's easier to buy an open ended OBD2 cable, solder the resistor inline and crimp on a RJ45 connector, or cut a RJ45 patch cable and solder that to an OBD2 connector like ImSW1 shows above?

Itschase,

Good to see you here! Your contributions will be appreciated! Please keep us posted with your findings.

@DreamCar; Well, isn't that freakin sexy!

@itschase; Thanks for confirming. Did you get CAS TC_MSA_MEMORY from my post on the other board?

Shawn,

I have been staring at that feature in the CAS for a few days, tempted to activate it and test functionality - but instead I wrote to the other Sean who confirmed this is what I should change.

@itschase; I wanted Sean to test it, but like me, he didn't have the feature on his car to test, so I had someone else testing it in a different board / thread and was still awaiting his confirmation. Thanks for confirming it instead!

Which I had initially stolen from Shawn. The circle is complete!

Sean

Though I would really love to do some of these changes, you guys are all talking greek to me. I'd be to afraid to try this on my own for fear of screwing up something else.
I also have a question; If you should require some future download from BMW, will this put the kabosh on all these self-made changes and cause the settings to revert back to the factory ones?

@romeofrosty,

If you update the software in the future ..You have to program these option again (Shawn correct me if i am wrong)

@DreamCar and @romeofrosty; Yes. If the dealer reprograms the car, the coding will need to be redone on every affected module. If the dealer only updates one ECU, then only that ECU will be affected. If they update the whole car, then every ECU will need to be recoded.

I build these by hand because I have network cable available by the roll. That being said, I believe that so long as you can see the colors of the twisted pair through the RJ-45 then cutting the end of a patch cable is the easiest method because half the work is already done.

It's really not that expensive either. You can get a decent 10 ft patch for $6-$7, throw a OBD2 connector in there $4.99, an RJ-45 and a resistor $1.00 each (worst case) and maybe $5 in shipping getting it all to you and your cable cost you $18.99. Not a bad deal if you consider it would have cost you $100+ to activate DVD in motion.

Shawn,

I have both ACC & HUD. Aside from the BMW logo appearing on start-up, the ACC does not show the iBrake distance. It does however, show a red car indicator if you get too close to the vehicle in front of you.

I would love to see the iBrake distance in HUD as well as the turn signals. Is there anyone in or around the Miami area that can help?

Thanks

@MCMB; Thanks for the info. iBrake Distance in HUD looks doable, but will need to be confirmed.

Ok. So I realize all of you are going to get a good laugh about this post, but what the hell. So from what I understand, all you guys are doing is going into the pre-existing programming code, and enabling or disabling certain features that are already programmed, but not enabled through certain commands. Unless I am wrong, no one is actually writing new programming code. So here is the question, if all that is happening is that you are enabling functionality that already exists (or disabling it as the case may be), for God's sake, why doesn't BMW just make these features part of the settings that we have access to through the Idrive Nav screen. I mean, its not like we already can't change a million things...why not make it 2 million. Or would it make the car setup process just too confusing and overpowering for the average Joe? I can't see why BMW cares if we want to be able to push a button on our key fob and simultaneously lock the doors and fold the side view mirrors. Or show some specific information on the HUD, or whatever. If I am wrong and you all are actually writing new programming code, then I apologize. But that's not what it sounds like. It sounds like you are just inputing certain already existing commands to cause something different to happen than what is "hard wired" as a default.
