I was very hesitant to install stage 3 because i drive this car for work and sometimes with clients in it. I couldn't have some boy racer hard shifting transmission. I went with stage 3 on a hope.

Turns out its amazing, in daily driving in D, no one would ever guess this trans has been tuned. Even at full throttle upshifts in D, they are smooth and very quick. No jolt, no hard shift, nothing. It shifts exactly how it should have from the factory. M mode is incredible. It's like driving a stick, shifts are fast and smooth, and most importantly, they are done when you click the paddle.

Haven't messed with S mode yet.

Simply put, this is the best 200ish dollars I have spent on the car. I used an Amazon Fire HD tablet, and a 18 dollar cable off amazon. I didn't disconnect my JB4. Install was smooth with no problems.

To anyone on the fence, buy it. It's worth it.

Very helpful information, did you have to do anything special with the software on the amazon fire? I'm running the jb4 w Bluetooth and everything I use is ios, I'm looking for a cheap android device to simply flash the xhp. I know they are cheap on amazon so if it will do what I need I'll order one tonight.

Is XHP revising these maps at all like MHD?

The OTS stages are very stable, so no real need to make revisions. RBT-Tuning has been concentrating on adding options to the Custom module; which is an add on.

All the time, yes. But unlike MHD we don't have one set of Maps for all vehicles, we have over 300 different ones for the various vehicles. So if we upload an update, it's not all the time announced somewhere...just the owners of the respective car notice it, when opening the app. (xHP downloads and messages accordingly)

Usually updates happen in the first months after release of support for a new vehicle, but at some point the maps are just fine and people can further adjust them with the Custom Module, if they wish.

The xhp flash shifting much faster than the stock tune one would expect to find lots of users ( not the tuner) saying that they improved their 0 to 60 and or their quarter mile times but I can't find a single one!
Xhp flash is no good for straight line speed?
Xhp only improves the times on a road racing track?

Hi , l will make some comparisons tonight , stock e91 335d , let you know how its goes
For reference

Well got some news
I have 20 kgs more due to more diesel in the tank vs the last time , a little lateral wind , and 4 degrees less c. Exactly the same place l do the measurements, but forgot to put the memory card on the pbox , will do some new test this weekend , probably sunday , even with the correction on the pbox the test are the same so trust me on this .
XHP stage 3 the last vertion in manual shift at 4200rpm traction control off


100-150 km 5,4 seg
100-200 km 14,8

1/4 mile

0-100 km 5,5 seg
0-100 mts 5,8 deg at 103,7 km trap speed
0-200 mts 8.8 seg at 132.1 km ts
0-402 mts 13,6 seg at 165,7 km ts
Start in manual 2 gear , 1200 rpm load.

Will put some verified data with the same weight etc during the week , but the car is faster and the xhp tune its a very nice change .
Thanks

[Jpm57tt]

Hi

Its reining over here , so l can’t take the measurements today .
I just bought a dragy performance meter and want it to test agaist the vbox , so during this week if the wetter allowed me ,will post the info.
Regarding to the XHP tune its fully adapted and the gearbox its running excellent, l have made some changes on the tune for my oun driving habits and its perfect.
Thanks for the product.
Regards

I've had about two weeks now with D-Mode modified, Increased Torque Reduction = move slider to the right = smoother shift. I like it.

1>2 = +7%
2>3 = +4%
3>4 = +1%
4>5 = 0
5>6 = 0

No change to Sport or Manual Mode.

Thanks for the insight, I ma use that setup as reference when I have the time.

Will increasing these values make the shifts quicker and crisper in D mode? In D mode only, my car has quite of a pause and hiccup while changing gears (in low gears it feels like i let off the throttle, then it shifts), In S and Manual mode the shifts are quick and crisp.

increasing value = increase torque limit reduction = shifts smoother

I guess that means decrease torque load on transmission during shifts.

Same here. It's so annoying... Did somebody find a solution to this "hicup" ??

Thats very likely a misconfigured Load-2-Torque map in the engine tune. Means the engine is pulling more torque during shift, than the trans is actually requesting to be pulled.

People have complained about the fact that with XHP there is a distinct reduction of power delivery and delay when shifting. Especially in D mode with a good amount of throttle input and when at wide open throttle. It is like having it mimic a clutch being used in a manual car.

When I played with the customization of shift RPM I raised the shift rpm and this reduced the effect of the power drop. But it is still noticeable. I have used several stages and versions of MHD maps and it has always been there. With the stock map, it is there.

So what is the solution? I noticed this after recently updating my MHD stage 1+ map to the latest version

We'll probably have to drive more in Sport Mode

Reduce the amount of torque reduction in the custom module.

When I saw that feature added I figured that may smooth that out. With the winter roads in Chicago, I had to put it off testing it. Rain will be cleaning the roads Saturday and Sunday should be about 40 degrees. I'll test that out then and report back.

To get it, just download the latest version on Google Play!

Is it also possible with this update to let the first gear slip a little more, to reduce wheel spin when accalerating from standstill. (6HP28, stage 3)

What kind of power supply have you guys been using when you do your initial flash? The only thing keeping me from buying xHP right now is a few of the guys on my local forum have advised that even a 20A power supply (someone offered to loan me one) won't be sufficient, and I risk bricking any electrical systems on the same circuit. Unfortunately I'm not in a position to spend hundreds on a charger/supply that I'll use once. Does anyone have any recommendations? Thanks

[IllSic_Design]

I use the 20amp setting on my charger when I flash mhd or xhp, never an issue.

[nextNME]

20amp should will be fine. I think mine is only 15amp continuous...
