- xHP DCT Flash For F Series BMW M2 M3 M4: Install & First Drive
xHP Transmission flash software for the F series DCT transmission cars has just been release, so we wanted to document installing it on to a BM3 tunes F87 DCT M2 LCI as well as share initial opinions on how the car drives in the various transmission modes.
The main reason the owner has decided to use the xHP software was the customisability you have over the way the transmission behaves during shifts and also for launch controls. Bizarrely, this cars 0-100 accelerations times have become very inconsistent with both the stock DCT flash and the GTS transmission software.
This comparison mainly focuses on the difference between xHP stage 3 and the GTS DCT software, however we will be back with a more in depth look in to the how xHP has changed the car in the coming weeks, once we have had a chance to properly play with the settings.
This is the cable we used to flash the car with xHP. - ebay.to/2ZOAMu2
You will also need a OTS style adapter, as we were using an iphone we used a lightning one - ebay.to/33AmVsA
The setup is finicky with the cable xHP on the iphone, so take your time to follow the setup procedure listed in the app. Also make sure you are running the latest version of the xHP software.;

"Always on the 8 ball when it comes to partying" HAHAHA
Ha ha ha, fuck....
XHP recommends 50 or so miles of stop and go before beating on the car for the trans to adapt that’s why I might’ve seen a little sluggish at first
Torque punch was what I noticed the most for my e92 dct n54. Put it to 7 and the punch destabilises the back tyres with each shift, it's a nice feeling
See now this car does that as it was before. It need negative torque punch.
What sort of power is your e92
@@ZeroTo60Tube yh the none M dct just has an option for sport for the gearbox not shiftlogic. Xhp basically gives me shiftlogic and I can adjust the torque punch or turn it off. I like it on 5. (Out of 7). Unknown power. Jb4 18psi with mhd bef. Maybe 350bhp on the road or a bit more. I had to deactivate drop down before the xhp flash came our due to clutch slips
Running mhd stage 2+ and xHP which go together pretty well. I love the xHP tune on my m2.
I was curious how it would work with bm3. Definitely feels like mhd and xHP are working quite closely together.
Eddie, I've got an E92 DCT running Stage 2+ from MHD and have been on the fence about xHP because it seems to REQUIRE the user endlessly fiddle with the torque punch etc settings. -- What was your experience with running more than stock power?
@@bwhobackk Sorry for the late response. I personally did not have that experience. All I did was use the manual or XHP tune at the top of MHD map choices, and haven't had any problems. I take off the torque limiter and run with linear throttle. So far no issues. I noticed without the linear throttle my car would jolt forward from lights. I really just think that's clutch wear and I need to change that out and reset my adaption values.
The purpose of Xhp tuning on DKG is not having faster shifts but avoiding clutches slips increasing line pressure after engine tuning.
Declan, the PS4S is a far stickier type then the Cup2’s on the street. Try a rear set and see the differences
100% this. Cup2's behave like a semi slick, and require a lot of heat in them to actually provide more grip than a PS4. For 99% of driving, the PS4 will have more grip on the street.
Torque reduction and limiting by gear should help.
On the N54 XHP allows torque limiting in 1st gear when brake boosting, not sure if it allows limiting torque on 1st gear on the M2, I'm sure if you play around with the settings you can get the 0-60 times down to low 4's. 👍
You can limit torque both with MHD and Xhp on the F-series M-cars. I have an M4 and have both. (If anyone wonders, 3 years later).
holy shit that launch was crazy.Thoroughly enjoyed this video though
N54 DCT running e50 here and it used to light the tyres up to half way through 3rd. Changed to R888s and only spins in first now..but they are LOUD. Interested to know how much of difference xhp will make. Keep up the good work guys 👍
Just flashed my 2016 M5 with this and a Bootmod3 tune and holy shit it is absolutely ridiculous
You sure its not just the massive power gain from the engine tune itself? Hard to find real life data on Xhp tune for DCT, seems like the auto trans shits harder...as per people's butt dyno
What you need are a set of PS4S tyres to hook, cup 2’s need heat in them to switch on, and are more suited to track use
I was able to get my OTS map f82 to run a 10.7@131 . 10.9@132 dragy passes on the street with 1.8 60 foots. Can watch vids in my channel against 700+whp cars, dragstrip, etc. The secret is TiRE. The LC mode has hidden nannies that pulls power even with TC off. It doesn't seem XhP had changed that. The only way to hook these cars off the line is a real tire (nto1r/ET SS). My car has multiple 3.3 0-60s and 3.6 0-100s consistently on street without burnout. You just need to practice and need a different tire compound. Playing around with torque reduction settings is a rabbit hole I went down in the past. Unfortunately, the way the LC logic works, whatever you pull out in first is mirrored in second gear as well, which can slow the car down. The amount of power you'll have to pull out to hook a Michelin tire is going to just make the car just as slow. Order a drag set up if you are serious.
Which OTS map were you running?
@@elgapitan MHD 2+ e30
2015 full e85 tune here, got 3.67sec 0 to 60mph, using 285/35/19 Michelin ps4s"s What tires did you use to get 3.3sec? Another thing the lowest my car launch control would go is 3000rpms, you suggest going lower for better times?, if I were to get xhp?
been reading a lot about this app, So I have an e92 n54 with dct. I have tried the 335is and 135is software on it and they shift the same but wuth different rpm launch control (5k and 3.5k respectively) and yeah, if you can launch it that low that one hell of a way of getting a faster 0-100 time. Spool street hast a few threads with setting dfor this software, having the most interesting for you guys would be the torque reduction and the different launch control mode (as de dct stock just dumps the clutch) maybe a combo of both and the rpm lowering would help a lot with the times
For me? Im interested in the different diff ratio you can install on the software so I can install the GTS software OR if this software by itself can give the crispier downshifts (for track driving) that the GTS softwares have since t he non M software is quite dull in the heat of the moment for downshifting
my car is a bmw m2 I have xHP installed, can you tell me which is the best performance setting, or better performance?
Thanks for the heads up. I will not update my older iphone with the mhd and xhp app
There's a WhatsApp group and Facebook group with DCT owners who have flashed xHP. Started with the N54/N55 guys which came out a few months ago. Most still playing about with it. Ken (Wedge) has it in his Z4 35is and I think beta tested the original release
Do you have details of how to join this group?

Excellent video, keep up the good work!
Cup 2 on the inner side of the tyre are not much different to a street tyre. It's the outer edges that are more grippy and you don't fully use them in a straight line. You should get R comp tyres to get the most out of straight line traction... :D
Really really curious about this and what you need to do to dial it in. I'm not same platform but I'm Stage 2+ E30 and also have DCT... just on the older e92 N54.
The tuning potential is massive. Changed a couple of setting after the video. Only making small changes at a time. As an update it only takes 5-10 seconds to flash the settings changes
I have a first gen DCT in an E92 335is it is amazing in manual mode, it will hold gears just like a manual, the problem is in comfort mode when you apply the throttle to the kick down it gear searches for the lowest gear possible and your going 80 mph in second gear and the tachometer red lines to the rev limiter, which triggers the malfunction lite
That’s not ideal. I don’t think that’s normal. But really not sure. You would be able to fix that with xHP as you can set all the max rpm shift points for different gears
Would i be able to remove the stock torque punch from M2 , its just stupid ?
Its definitely a preference thing. It may unsettle the car, but try both.
This is why the cars are changing to the ZF as well......way way way more consistent launches and better low speed manners, for slightly slower shifts in full attack mode. I can reel super consistent 4.4's off in my 140 because of it. just mash and go.
Personally i think i prefer the ZF8 as well. I used to think the DCT was the best thing in the world. Until we started winding the power up in this car. Hopefully with some tweaking xHP can sort it out. But yeah the zf8 is so forgiving.
@@ZeroTo60Tube For straight line at least. M2 isnt really a straight line car, so the DCT/DSG is a good choice still for track.
Wich exhaust is on?
I have stage2 with mpe en downpipe en its outrageous louder then this
ASBO = Anti-social behavior order, excellent British slang
LOL, where the mic is makes it sound like a cummins
As per Racebox (aka Dragy) I ran a 3.67 0-60mph in my 2015 f83 convertible m4. I want to know if Xhp is worth it for my DCT? or is it on one of those "I think it feels faster?" I have michelin pilot sport 4s' 285/35/19 in the rears. 100% e85 tune, catless downpipes. I don't have Xhp, but i have MHD's GTS transmission flash, not sure if it helped and the lowest my launch control would go was 3,000rpm's. Some spin, but launched kind of well with ambient temperature of 85F degrees. My convertible top was down was maybe all the weight on top of the rear tires helped traction..
I think its a no brainer, but i get in to all the settings xHP offers. Its not night and day on a m car for every day use. However customising the launch is priceless if you car is making good power
I'm so impressed by your time! I have an F82. MHD stage2+ with catless DP and comp exhaust with the small cats left. I found E30 is much more torquey than E85. I don't have a custom tune. I ran 285/35-19 Bridgestone Potenza sports which are a more sticky tire than yours. I just bought Xhp and done some mods. Didn't like the OG, CS or GTS trans tunes. I made the car much more usable by lowering the shiftpoints in the lowest gearbox setting so I can use Sport on the throttle map which is linear., HUGE improvement and I'm only on my second day with it. Used Xhp with my 435i too that had the zf8. That trans was setup up perfectly.
Either blow off springs are too tight or they aren't getting enough vacuum
Wondering what gives you that idea? This is fitted with the turbosmart upgraded BOV. From memory its the electronic one, so no vacuum.
what power supply unit did you use?
I like this guy !!! lol
Can you adjust the boost in first and second gear and retaining full boost in the rest of the gears via xhd ,there by you can launch the car better
You can only limit torque with xHP. Which we haven't played with yet. The BM3 tune limits boost. However it only able limit a percentage of full boost in 1st 2nd and 3rd. So the car runs the biggest reduction which is 50% in first gear. This would still light the tyres up effortlessly with the default minimum DCT launch rpm. With the stock flash the lowest launch rpm was like 2750 where now we can launch from 2000rpm and it spins up so much less. Hoping to try torque limit instead of boost limiting in the next few days. But wanted to get some miles on the car with the new tune before going crazy changing settings.
Zero To 60 thanks for your elaborated reply ,please keep me posted if there is any difference between limiting the torque via bm3 tune and xhd tune ,Iam hoping xhd tune can be just marginally better.What is the power and torque figure you’re currently running . Iam going for the mosselman turbos and xhd tune for my M4.
Can I GTS flash my transmission only with an iPhone?
Not sure
@@ZeroTo60Tube thanks for the reply. It can be done with MHD tuning.
Big fan guys keep it up, what's the 0-100 app you guys use?
This was dragy. Really recommend dragy or vbox. Most other apps are generally questionable when it comes to accuracy. To be fair I think dragy is even a little generous, but the internet thinks it’s fine, so run with it hehe
@@ZeroTo60Tube Thanks boys legends! Haven't had good experiences with some other ones and the apps you boys use seem to have a good interface as well, have a good weekend!
MY CAR IS M2 F87 I WOULD LIKE TO KNOW WHICH STAGE XHP WORKS BETTER WITH BM3?
This was tested with stage 3 only. I dont think you'd ever need less than stage 3. Stage 3 is still very smooth when driving normally
I like you guys video! I want to know, if I purchase and redeem the code, how long can I access the function?
It seems to work straight away.
Zero To 60 thanks guys!
is there an update video?
sooo 135i N55 with DCT and xHP can shift as good as M2 with xHP? I've heard that it's the same trans.
Very similar hardware in the gearbox itself. But they do have different electronics and the way the ECU and TCU work together, even xHP has different options from what i have seen. That said, the difference in regards to the e series 135i dct shifting as well as a f series dct is negligible. With the xHP software on both the 135i should be as good as makes no difference.
@@ZeroTo60Tube I need to test drive that little bastard (135i e82) and compare it to my e92. M2 is a dream but 135i maybe a reality :D
E92 N54 with dct ?
@@ZeroTo60Tube nah, just e92 325i, lack of power is little sad so I'm looking for something else. I think that n54 might be a little troublesome and pricey.
MrDrako009 I have the XHP dct flash on my 135. After adjusting some of the torque values in XHP shifts are instant and crisp.
👍👍👍
I can’t get xhp to open without insta-crashing on my iPhone 11. You guys have any issues?
Edit: ok jumped the gun on my comment.
they're apparently releasing another update to the app on Monday because of the ios14 crash
michael cohen excellent, finally got me Thor and I couldn’t program it. Frustrating
What intake is he running?
From memory it a Eventuri
Test out Thor dct flash vs xhp
Xhp is much better than the Thor flash. I ‘v tried both of them.
@@user-xp1ub1ej5e is it a much noticeable difference I know with Thor I get little upshifts pops do you get that with xhp
4.5 only?
This car did a 4.4 when stage 1 and the more power that’s been added the less consistent the 0-100 times have been due to wheel spin. It’s been very hard to launch with the previous transmission flashes.
Your tyres spin because they are very high performance tyres and need heat to work best
You are correct they will work better with more heat in them. But it’s not a massively noticeable on this car. Even with tyre temps at 70-80c post track it will still light them up on a launch.
In contrast I have recently driven a 1m with stage 2 e50 mhd and it pretty much dead hooks with its manual transmission.
The m2 has been a tricky one to sort out it’s traction. Boost limiting in BM3 didn’t help. So hopefully xHP is the answer after some tuning of the options.
Zero To 60 I have a standard F20 M135I manual with Michelin pilot super sport and they spin in 1-st gear. But they are temp sensitive tyres.
Crank hub fix or no? If not be careful with launches.
What is the issue with the crank hubs and launching? I thought it was over reving manuals that normally hurts the hubs.
The crank hub is only an issue on the S55 engine in the M2 comp, this M2 has the N55 engine.
Jason M it can happen to N55’s & N54’s with the DCT like it does with the S55.

Launch the car daily, constantly hit the limiter, sharpen the clutch engagement, increase the rpm limit, and something will fail. N54, N55, & S55 all are held with the bolt and a friction disk. It can happen.
think the s55 spins easier due to the timing system drives two hpfps instead of one, the timing system also drives a larger oil pump, timing system also drives a water pump which is not electric on the s55, and the dct down shifts alot harder than non dct equipped N54's and n55's. This makes some sense since the s55's have been reported to spin even while cruising.
I've never heard of high power n55 or n54 spinning crank hubs
Seems like a waste of money
With his sunglasses on he looks like Elon musk.
I was expecting the DCT would be a little bit faster than this. I've seen ZF8HP which is not dual clutch, with xhp stage 3 and is as fast as this one here. Audi DSG is a bit faster...
The stock DCT is quicker than a ZF8. ZF8 BMWs dont show true RPMS on the tacho which does deceive a lot of people. ZF8 is an amazing box, probably my favourite. But when you drive a true M car with DCT the harshness on the full power shifts between dct and zf is no comparison.
Is the driver Elon Musk? Lol
Elon’s mad nephew..... lol
lols
Elon musk before he got into electric cars. And who knew he was aussy?
Hahaha lol
