XHP Flashtool - F8X DCT Transmission Tuning Software Tested!

I was lucky enough to Beta test the XHP Flashtool DCT Software on my M2 Competition and I've been given permission to release some feedback as a teaser for you folks. They said the software will release in a couple days to the masses. For those who don't know, XHP has been releasing transmission tuning software for years and they have one of the best customer support teams and offer THE BEST in transmission tuning software for BMW's period. I've had their software on my Diesel X5 and it really woke it up...does the DCT really need waking up? Read below to decide if it offers something you may want.

So first off check it out at https://www.xhpflashtool.com/ and read the manual. They have a connect diagram here: https://www.xhpflashtool.com/connect_diagram/ which shows you the flashing options. I am using an MHD Black Wifi adapter which I also use for Bimmercode and it's super fast.

Flashing takes around 2-3min for the first flash and any other edits to the Shift maps, torque punch, or flash back to stock takes around 10sec.

Initial driving impressions are great and nothing seems off; I highly recommend it! I definitely need more time to go through torque punch and some other settings; I did find the OTS Stage 3 map shift points are definitely aggressive and high (likely GT4 or Hybrid turbo cars). I elected to go with the stock shift maps. They have made it clear that full shift performance is only available in M-DL3 + DSC OFF which makes sense since the traction light usually illuminates on most of my shifts anyways.

Cost is around 450-500usd total for the Flash License and Map Package. The increased clutch pressure at 19bar alone is worth the upgrade. For those who don't know, this pressure increase has been dyno tested by Maxxecu and it shows the OE clutch torque handling capabilities are up over 100ft-lbs easily with this. So before wincing at the price think about the cost of a clutch upgrade by comparison. See link for data: https://www.maxxecu.com/webhelp/adva...e_upgrade.html So those of you with hybrid turbochargers who are worried about slipping clutches, may be able to get a lot more time on a set of stock clutches without upgrading. Keep in mind launch control and heating up of the clutches through abuse is not going to save them but at least the increased clamping pressures will help.
As a comparison of clutch pressures:
OE M3 - 15.5bar - 650ft-lb
OE GTS - 15.7-16bar - ~680ft-lb
Maxx ECU Dyno Tested - 17.5bar - 740ft-lb
(*Info gathered via MaxxECU link posted above)

XHP - 19bar posted - ~Potentially 800ft-lb? Need to verify if the pressure goes this high.

Attached are some screenshots of the App and the option menu along with some more details on the torque punch feature.

This is perfect, thanks for the update Kent!

I'm for sure getting this when they release it.

D1 is very smooth I will say, nothing bad to report. I don't drive in D1 very often but I did try it; I can't say if it's smoother than stock because it felt like stock to me.

I can't wait for this! Does this get rid of a part of the power pull and clutch slippage that LC does in the OTS GTS map?

Word of caution, the current version of xHP does NOT work with iOS 14. Not sure if the updated version will. I'd keep away from iOS 14 in the mean time. I'll do some testing with my spare device once the updated app comes out.

I can confirm the beta software does not currently work with iOS 14. Luckily I have an old android that never gets used so it will handle the XHP for now.

xHP just released support for the S55 today in the iOS app store. Looking forward to hearing impressions from others now that it is public.

Is the TCU mapping as complex as DME mapping? 400€ for maps + license sounds a bit too much for me vs. BM3 being 500€...

price is definitely on the steep side, but its something you have to feel for yourself. I think its definitely worth the money.

Worth the money. I can reconfirm error is still pressent, car not show in support check but when you enter in My vehicle option in app if car is connected it will appear here with VIN and everything, you just press on it and you can redeem codes(codes you can buy from their website, fast and safe). First flash take around 10minutes but after first flash it takes around 1 minute. First tests directly on stage3map, i raised revs from 3 to 7thgear with 15%, now 7th gear is engaged at around 80km.h, before at 64kmh(i am talking about D1 setting at gearbox). And one but not last nice option, i disabled creep mode(that mode when you put car in D and press a little bit acceleration and car start to move very agressive or when you try to stop slowly in city driving and car do a little shaky and aggresive disengage, now car run in first gear only if i touch the gas and keep it touched). This mode is very useful for me because i have a tight garage and the risk of touch the car on the wall now is reduced.
Sorry for my bad english, is not my first language.
