I drive only in 'D' on my 330D but am still looking forward to xHP when it becomes available for my 2006. I'm just hoping it will run lovely with my remap.

[JMM]

Mmh yes i get the drive but...BMW had once also things well thought of what an automatic gearbox should be for the crowd in D, S and M- mode..and...yes they were apparently fully wrong, espacially with the S and M mode and that wrong fact/thougt?.. gives the xHP tool the full benifit to prove that.

But what i meant is the fact that the OEM D mode is not that inferior according to the D-mode in the xHP software...but problably i will be very wrong in others there opinions, like i understand it from your comments.

I can absolutely not see the unbelievable benefit between the OEM and xHP software in D mode like the huge improvement with the S and M mode and also the big improvement with the paddle reaction times...
Sry, guys but i consider D-mode for lazy/comfy driving.
In my opinion with comfy driving it's not that important if the tranny shifts fast or not, even if the shift times are a bit lower or higher.

If i remember in the "let's do it ourselves" forum, the primary goal of this software was the fast shifts in S an M mode with improved paddle response times and all that primary for the 335d's.

I rest my case.

[2007BMW335i]

Everyone has their own ideas about how a transmission should behave and it's related to both how you drive and what powertrain you have.

In my case I daily drive a car with about 500 hp (N54: 440 hp and 550 ft/lbs at the wheels) I almost never use sport mode but I still need the transmission to handle the added power because part throttle driving on this car is nothing close to "lazy"

I wanted:

Crisper shifts and holding power for when I do get on it.
Gear shown in cluster, for the times I do grab the paddles.
Quicker paddle reaction times.

When I do actually drive the car hard, I use manual mode, turn the DTC completely off (the car accelerates so fast it will initiate traction control even without tire spin)

If I decide to go do some spirited driving in the mountains I will give sport mode a try. I'm sure it will be great based on the limited driving I have done in sport mode around town.

So, for me xHP stage 3 checks all the boxes. EXCEPT

The one thing that is missing for me is being able to pick my wide open throttle shift points, because the stock turbos and hpfp cannot keep up over 6000 rpm (at this power level). But that's just me being lazy and not wanting to shift manually at the dragstrip or any other time I go wide open through a shift point.

N55 335i here. I'd love a map with stage 1 D and stage 3 S/M. My car is my daily driver and the stage 1 D was smoother and better gas mileage than the stock D. I love the stage 2/3 S/M but the more aggressive D in those stages do not appeal to me. For me D is my commute, S/M when I want to get on it for whatever reason.

[JMM]

I have to admit that there is one common benefit in D and M mode over the OEM software en that is the longer maintaining of the gears at the lowest possible rpm.

It's for me a handy characteristic of the xHP software if driving behind a slow someone and you or the car himself can stay just in that higher gear.

I totally agree. I've been wanting the set rpm limit for years. Seeing we now have a tuner who can do this, it only makes since on stock turbo cars to have auto shift at 6400 rpms to stay within the optimal power band. Inlets and upgraded turbos would make a difference. An option to pick your limit during flash time would be ideal. Maybe if more people want this option, RBT tuning will add it. No need to be over revving turbos creating heat and wear unless you want to a have a little fun in manual mode.

And the downhill experience...hmm...I guess you experienced the downshifts while braking? Theres no extra downshift programmed for downhill.

Early build '07 335i here with Stage 3 v1.6 flashed currently.

I have experienced unnecessary downhill downshifting under light braking. I have a steep hill near my house and while in D around 35 or 40 mph it will sometimes shift into 2nd and send RPMs up near 4500. Only way out is to put it in manual and shift back to 4th (where the stock D would have it)

Nevermind!

update

flashed my car with v1.6 (9/09 build n54)

my only complaint previously was little jerking forward motion while downshifting from 3 -> 2 at 2k or so rpm in M mode.(downshifting at higher rpm was fine)

with this update, the jerking forward motion is gone!

keep up the good work!

Nice going to try it, I went to Stage 2 because of the jerky lunge forward shift from 3 -> 2 and also down to 1 at anything higher than 1500 rpm.

Just managed to flash Stage 3 XHP to my 2009 N54 E71 X6 35i, I’m experience a slippage on 5th gear around 4900rpm. Car mod: MHD Race flash, JB4 24psi, 100% Meth S/cm10, full Catbk, 93 pump.

Anyone with the same experience mind to share what’s could possible be the reason?

Thanks

i posted the same message and i was getting the downshifting under light braking in the past 2 updates as well .. im pre 03/2007

also harsh shift from 2-3 in D mode pretty much all the time

[Silent9n54]

pre 03/2007

still getting jerky lunge forward shift from 3 -> 2 when in s or m mode

im on stage 3

i noticed that stage 2 is still on v0.9

are there any updates coming to the other stages ??

im glad i didnt buy the full package since the other stages never get updated

Not sure if this is the right place....by according to VIN DECODER, my 2012 335i (build date 2011-09-15) is a Type code KG73, but when I plug in xHP and it pulls what is compatible for maps, it shows a KG7C, and ready to buy this but need to make sure which is right and which is wrong before I do this. Anyone else have this discrepancy before?

KG7C = KG73

Ok, thanks, what pops up is correct then. Because I did see separate maps for each in the store BEFORE I plugged it into my car. On my schedule for tomorrow...only have 45 minutes before I leave for work today, not enough time to do everything the first time according to the How To videos I watched last night.

did you flush your tranny?

[Segments]

Need some advice from the ST auto guys; so recently I've noticed what I believe are torque converter issues. I've noticed a stutter in a few different forms whens driving. In the first video + log you can see my RPMs initially drop when tipping into throttle, then come back up into normal acceleration. The second video then shows acceleration from a dead step, during which RPMs are very choppy. I'm running xHP St 3 on a big power N54, 2008 135i, and have done everything from upgraded plugs, coils, tranny fluid, tranny cooler, changing tunes, flashing the stock tranny tune, so I feel as if Ive removed almost every other culprit out of the situation.

My next question would be: would it be a better idea to replace the entire tranny or just the TC? (Or am I not giving tranny long enough to adapt?)

KG7C is just an alias BMW is using for KG73 in US. I don't know why that is. We have to have both in our database, because some vehicles identify as KG7C and others as KG73.

Actually, this happens on all xxx3 typecodes in US. In the beginning we had a lot of emails from users about their cars being not supported. Thats because the xxxC codes are not listed officially. The BMW tester converts a xxxC reading automatically to a xxx3.

Looks to me like TC failure. Either the TC is bad at all, or the actuation of the TC clutch. (so the issue sits in the Mechatronic) It's hard to really nail it from a distance, but a ZF service shop should be able to localize the problem.
