Your Newer BMW Has An Imitation Limited Slip Differential. Mine Has To Go! - E90 Coding

- In this video I go over the electronic differential locker that is built into the dynamic stability control module on BMW's from the last 12 years or so.
I explain it in theory and deactivate the function in my control module as it will likely interfere with my new mechanical limited slip differential.
Here is a link to the playlist where I convert my car to have an LSD:

Brilliant video helped me i run a welded diff in my drift car and with dsc fully off the e diff was trying to apply brakes and bog down ive since followed this video and coded the e diff off and it spins them like a trooper
Just bought one of these kits awaiting to see your review. Please hurry lol
And again all my questions get answered by you without even asking
Perfect ! I just installed the M Factory LSD in your cloned Bimmer...
saved the video because I am far from cranking
Daaamn I didn't know that! That's why my F20 after some serious sliding on snow cuts power or trow a dsc error! Thank you so much!!!! I'm definitively going to install an LSD! Do you also know the procedure on f20 platform? It would be so usefull!!! I'm also watching all your latest videos as i also have the b48, man thank you so much for your help!✌
Just wondering, the LSD conversion was installed 6months ago... how come there’s no long-term driving review yet? Did you end-up removing it...?
All the clutch type diff I ever had had to be finely tuned with slip fluid additives. You add the proper fluid with zero lsd slip in it then add 10ml of LSD slip fluid at a time until it works correctly. I never seen a clutch pack type LSD even a factory stock one work correctly with out doing that. IMO car manf. are afraid people will get hurt in the rain with a too aggressive LSD. Inthe 80s toyota put a 14 clutch lsd in the MKIII supra and people crashed and died from snap over-steer due to a strong aggressive LSD. A lawsuit resulted in Toyota modifying how they build/assembled the MKIII LSD, they just disabled the clutches by packing them backwards I still see this sometimes when rebuilding them the correct way.

You can do this nanny removal with ProTools very easy. If you haven't checked out protools it's a must for diagnosing and coding tons of BMW platforms. I use it on my 335i and it's great. Love the RUclips channel man keep up the great work. PS I have one of these racing diffs LSDs and I've had hell trying to find a machine shop locally that will grind my gears. It's been a letdown so far :-/.
Good tip thanks! Try contacting shops that specialize in grinding, from what I found your average machine shop can't do grinding of hardened steel.
@@VehicularDIY I actually went to a place that does industrial grinding and the topic of holding the gear came up. I have an idea, hold the gear with a cut down output shaft. Put the gear in it's natural locked down position with the circlip holding it on the shaft. Then have a large washer under the gear base and weld it in place. That way the gear could never push down past that point.
Hey you answered the very question I wanted to know. Thank you! Protool is awesome! I bought it and I've never touched INPA or NCS again since!
As always very detailed videos. I dont have a e90/93 but i'm will some time soon preferably e93. keep it up and thank you for the content 👍🏻
Do you have any long term feedback on the racing diffs lsd conversion? Especially interested if you've done any circuit track driving
I've always call it a reverse LSD as it cuts power rather than send power to both 😂
My exact complaint about the system as well! Not the way you want anything related to power to the wheels to work. Cutting power is the opposite of what I want to happen.
Great video. Thank you.
This video was posted 7 months ago in may!! Great content but the pinnacle of this conversion is what it's like turning tight corners in day to day normal situations.
Do you have any videos regards to the car hopping or jumping due to it being locked too much for slow and steady turns, say in a car park?
Thanks in advance 👌
if we weld the open diff can this still work?
My assumption was that DSC doesn't interfere with aftermarket LSD any more than without , anyways you can turn DSC off right, long press. Will have to look into this when LSD some day
Yeah a long press does disable everything but the diff locker, it's always active even when you turn everything off. It'll let you light up your tires but it's always there and will eventually cut engine timing to stop the brakes from overheating.
@@VehicularDIY I see, first time I've heard about this, interesting
Can you please do a video of this lsd in action? Would like to see some results before I buy the kit
Damn god i can’t wait for the final review!! Haha
Did the review ever happen?
Great movies!! What is your experience driving with the Racing Diff? Do you recommend it?
Do you think its possible you can make a video on how to disable 2F8F Accelerator Pedal Module and Brake Pedal
Good stuff mate
What did you notice different after coding the ediff off? Can you feel both wheels accelerating equally on the straights and turns?
Nice coding DIY. Keep up the great work!
Why didn't you just use protool? 80% easier than manual coding with ncsexpert/dummy
Omg i just used that protool its so good. I used to inactive the dsc locker diff with dsc. It works on 335i e92.
Would you happen to know if E61 535d 2008 also have this eLSD ? I have install insides of M5 diff to mine and i dont know if i should look into that or nor hmmm
When mine n54 335i has full dsc off with open diff for most burnouts i do allways have 2 tyres marks. the other day i done 2nd gear launche spun 2 wheels all the way to red line. So the e-lsd acts like a actually mechanical traditional lsd diff?
From experience with an open diff it is possible to get 2 tires marks if the conditions are correct but it's hard to get consistency. The ABS controller monitors wheel speed and if one wheel gets too much slip it hits the brakes on that wheel to send engine power to the other wheel and when that wheel gets too much slip it diverts it back etc. That helps but ultimately you're hitting the brakes and slowing the car down to keep it stable but it's better than nothing. It was basically free for BMW to program that into the DSC module so why not. I guess you could say it's a form of computerized torque biasing. I'm not an expert on this and there are various types of LSDs but I'd say a LSD is naturally partially locked at all times and when you overcome one wheel it uses momentum to clamp down harder to try and maintain lock.
@@VehicularDIY thanks for ur knowledge appreciate it.
Not sure if it's just me, but I followed the steps exactly and when I re-read the ECU down into NCSDummy, the settings are reverted back to stock. So it seems like the changes are not sticking. Have you verified that your changes took?
Do you know of this coding would be available for an F10 550i (N63) X-Drive? I want the dang E-LSD to stop nannying when I am wanting to power slide or all wheel drift.
Did you test out the diff? How is the lock up ?
Can I ask you a guide for coding in the eLSD? I have a 325i e92 2007..
Huh? I ordered one of these kits too, one of my specific questions to the manufacturer was if coding for the dynamic traction control was necessary and they told me no. I can't even get inpa to download properly on my laptop. Bought 2 versions on eBay and even tried to download the sketchy online version but it won't run. I'm screwed

Bro i got racings diffs lsd kit now. Should i code the e lsd back?
Love the vids!
If the limited slip is doing its job and the DTC DSC is turned off I’m confused why you would need to code this out? I understand for review purposes you want only the LSD borking however, if the limited slip is working the system to even come on. I purchased the same limited slip and waiting for the final verdict before installing!
Sorry or the grammar and misspellings tried to dictate the message.
That was my logic at first, I thought maybe it would compliment the LSD but really it seems to just cause the DSC to be in the dark when a slip is about to occur as now both wheels break loose together and it's like it shocks the system and it kicks in hard. Before you could power through and barely lose momentum if that make sense. I think the car considers a sudden loss of traction on both wheels more of an extreme situation vs one wheel losing traction as that's more of a normal occurrence.
So, where and how do i get this kit sent to Poland? Is it reliable long term? Im thinking about getting one to my e92 n54 manual. Hope someone can give some details ;)
Wish I lived near you man I have a 09 I would like to get coded. Great content keep up the great work!!
Any idea what this is? Trying to send a picture
Have you confirmed that a hex value of 00 for brake overheating is actually off. I have a 2007 335i mk60.87.coa module which I believe come standard as 00. Also, when you coded the values off, did it stop the power reduction and braking? How does it drive compared to before coding? Thanks.
Hi mate, quite late reply, but my 325i also came stock with hex 00 which I believe was Power reduction on. Then I coded it to wert01 and it seems like there is no power reduction now. Have to do a proper test drive but so far it feels great.
Very good information and well presented, keep this type of content coming, thanks! Greetings from Sweden 🇸🇪 👍😀👍
Is that whit the traction fully turned off or on if so I was wondering why my e92 335i was a bit sketchy while going sideways.. Awesome info
Yeah with traction fully off it will no longer step in. Technically on these cars the electronic diff locker is always on so you never really have traction full off unless you do this coding. From what I've read it's way better to have this unless you have a mechanical LSD which I do now so I turned it off.
@@VehicularDIY awesome cheers for the reply
I followed your instructions on coding the diff and the value for engine power reduction was already at 00 for me while the diff lock was at 01...any reason why it would be at 00 ?
What year is your car and did you have a C0C module or C0F module?
@@VehicularDIY mine is a MK60_87.C0A
@@VehicularDIY forgot to say its a 2007 335i
Didn't work so ?
Don’t suppose you could remotely code my bmw WBAWN72050PX72600 it’s a 330i or do you know if this model doesn’t have this software it’s so difficult to find out.Best group informative videos I’ve seen in a long time hope you get weather for next Friday.keep up the good work Thanking You in anticipation of your forthcoming help and co operation KARL

Will this work if you running jb4 with mhd backend flash? Would this coding affect any of the two?
Yes as you're only coding the DSC module. It's independent from the ECU and won't hurt your JB4 or MHD flash. You'd only want to do this if you have an LSD, I've heard the car drives terribly with a stock open diff and the E-Diff coded out.
@@VehicularDIY yeah I can imagine how terrible it would be to drive with the e-lsd.
I distribute the Racing Diff products in South Africa and have just fitted the conversion kit to my personal car (135i 6mt), so doing this will really help.
Nice, once you install it be sure to chime in letting us know what you think as well.
Hey friend, let us know what you think! We would love a review video!
I own an bmw 330d e91 lci 2009/06. I believe my car don't have an e-diff. Could you potentially code in the e-diff?
If your car is a 2009 then it would have e-diff already activated from the factory.
@@VehicularDIY Are you sure? Even when dtc and traction control of? Or only with it on? I often break traction and nomatter what i never experience power loss because of heat in break...
@@VehicularDIY You know what, im going to check right now...my vehicle is an EU car without m-pack. From what i can read, it should not have it. But my guess is that it could be active. I could save 0-60 time with an e-diff. Running 275/30 just to get the power down :/
I have an n57 engine with a tune, ton of torque! Always breaks traction!
So why no follow up video, did it suck so bad?
There is a follow up video but I haven't hit the track yet to test my 60ft. It is a good traction aid and the performance hasn't degraded. If I can cut a sub 2.0 60 ft at the track then it's doing something.
cmon brother you gots to hurry up a little lol, want to see this baby do some quarter mile passes 😁
lol yeah I hear you, I wanted to go tonight but we're getting a lot of rain in Houston. Planning on next Friday.
@@VehicularDIY oh man thats another week of waiting, lets hope the weather clears up and you make a hit 🤞🏻
Looks like they're $340 now...
can you open that diff up? I'd be interested in seeing the electronic "lsd"
It's just a completely open standard differential, the traction control module is what always regulates how much spin one wheel can get before it applies the brakes and tries to shift power to the other wheel which hopefully has more grip. I just deactivated that system in this video. If you want to see the inside of differential check the video description, there is a playlist where I pop open my stock differential.
@@VehicularDIY gotcha, thanks. From your video title i assumed you were saying it has a locking diff. I honestly skipped through most of your video were you probably mentioned it in detail. great channel btw.
@@VehicularDIY "
It's just a completely open standard differential ..." is the salient point. There is no Electronically controlled clutches in the open differential, hence no "E diff"nor "E LSD."
Gee, no BMW doesn't have an imitation of LSD, it has a classical open diff with the most standard traction control applied through braking of the opposite wheel. And it is not true that you can't turn it off without coding. Turning DSC off doesn't turn off traction control for open diff, but holding DSC button for couple of sec you turn off DTC (dynamic TRACTION control) and your open diff is 100% open.
I've seen from multiple N54 forum postings that in dire situations the electronic nannies will still kick in, even if you hold the DTC button for 3 secs to "turn it all the way off". So, coding it out seems like a perfectly fine way to save the time of pressing the button as well as ensure that the system doesn't turn back on when you don't want it to. To be real here, anyone going this far down the rabbit hole is doing it for a reason. See: www.1addicts.com/forums/showthread.php?t=719012, www.e90post.com/forums/showthread.php?t=944126, www.bimmerforums.com/forum/showthread.php?1306940-How-does-the-DSC-button-Works.
An open differential modulated by a computer using ABS hardware is in no way either an Electronic LSD nor is it even a fake imitation LSD. This is admitted openly by the poster when he speaks of over heating rear brakes and the cars traction control programming to prevent such a condition by even reducing engine power if either brake disc temperature approaches a predetermined limit.
In a true mechanical, even one with electronically controlled clutch plates, there is no loss of power in transferring power to which ever rear axle that has traction beyond slight frictional losses. When braking occurs in any differential, power is converted to heat, a lot of it. A LSD will only over heat at the track if required to redistribute high levels of power frequently over a long period of time. Clutch type LSD will generate the most heat, but this is easily over come in extreme cases by cooling the lubricating fluid with a pump through a radiator.
So the next time someone starts talking about an open differential governed by a computer controlling the ABS pumps as an "E-diff," know that it is patently untrue. Same for a "simulated LSD;" there is no such thing.
Excellent coding tutorial, per usual.
