Can this be changed? If not, I will just flash back to stock and forget about it.

This has been my issue.
it's great in sport + or with tranny in S mode
But in Drive even accelerating hard it upshifts way too quick
I don't want static shift points. if I'm on the gas 60% I want it to hold the gear longer than if I was at 25%

Going to experiment with the shift points - I assume it can be changed to suit your driving style.
I just read this: https://www.xhpflashtool.com/blog/ho..._logic_of_8hp/
The way I understand it is that unlike stock, D is now more of an eco mode with low shift points - selecting sport+ in D just makes the shifts quicker unlike stock where it raised the shift points. With xHP you need to use S to get higher shift points - unless you alter the map settings.

i think you can edit shift points in xhp settings and also if you prefer the stock shift points instead you can select that as well and still keep the benefit o having torque limiters removed

Was tempted to tranny flash my stage 2 BM3, but i live in the U.A.E, and the weather in the next 5 months is between 40 and 55 degrees. Is there really a point of flashing it from now if i wont even be driving the car in Sports+?

Gents, I am contemplating on getting xHP. However I see the same question escalated again and again, which is a bit concerning.
Can you, actual users, please provide feedback:

[COLOR="DarkRed"]Does xHP reduce the speed of shifting in Comfort + D?[/COLOR]
Please note I am not asking about shift points, but about shift speed!

In other words - would I have a feel of degraded performance in Comfort + D and does this depend on the particular Stage?

Anyone here mess with the shift points on an upgraded turbo car? I have XHP stage 3, and loved it on stock turbo but since installing a pure800 I feel like the shift points for automatic mode are very off. I know pure spools a lot later, like around 3200rpm. I feel like it's shifting right as it's starting to spool up and doesn't feel right. Anyone have better settings?

When I went to flash the car this afternoon, I used my mhd black wifi adapter. Everything seemed normal and it started going up in percent as it was flashing. It got to 7% and then the screen switched to "finalizing" . It stayed on that screen for about 3 or 4 minutes then switched to another screen saying flash was successful. then cleared all drivetrain malfunction codes. I waited, turned the car on, drove it around for a few miles, and everything seemed to run ok with the gear select indicator now saying "D1, D2, D3, etc" instead of the "D" it had before. When I check the car with the xhp app, it is indicating I have the correct map flashed that I selected (stage 2 w/ version numbering). There are no error codes stored in the tcu.

Is it normal for the flash to go up to 7% completion then jump to the finishing screen and be stuck/frozen on that screen for a few minutes before the "flash successful" screen? I thought it would get to 100% and then go to the finishing screen. I have emailed rbt/xhp about it and am awaiting a response, but that seemed strange to me.

I can't remember for sure, but I seem to recall mine didn't increase linear or logically.
It might have got further than 7% but I'm pretty sure it didn't get to 100% before finalising.

It also flashed far quicker than xHP said it would take. Easily than a minute.

I've had no problems at all and works exactly as expected.

[Stucks]

Just in case anyone runs into the same thing that happens to me a few posts back....its normal apparently.

Can anyone weigh in on whether the xHP flash does anything to help the 0-5mph throttle lag?

Moving the stick to the left and driving in sport mode seem to mitigate it a bit, but it's still infuriating when trying to merge into a small gap in traffic or make a quick left turn across a busy street.

No, it doesn't. I hate it.

I'm repeating my question from a few months back... still unclear to me

[imperfectluck]

@Skyhigh realized you were left unanswered and in regular comfort D, it does shift slower which is my biggest gripe as I find myself turning off traction(single button press) to get those faster shift speeds once the oil warms up a bit. It's been discussed in other threads, it does baffle me a bit on why it does (have stage 2 flashed) shift slower than stock but I've learned to live with just having DTC on though I know this may not be for everyone's comfort and still enjoy the aggressive shifts of sports+.

Thanks for the feedback!
May I ask why you prefer Stage 2 over Stage 3?
Also - what are your adaptation values? Strangely, I have one Quickcharge time of 46ms whereas this, according to xHP, would be "out of tolerance".... and I have very low mileage on the car, which makes it odd...!?

I cannot remember what mine were, but one clutch pack was higher, and around that amount.

I actually really enjoy stage 3. I found myself always driving around like an asshat in sport+ before. Now on my way to work / warming up the car I stick to D mode. It feels safest for the car. You can move the shifter to S and the car will shift the same speed but hold gears longer

Whenever I want to have fun I usually do sport mode as the drive mode. This changes the throttle response and has a modest increase to shift speed. Whenever I want to push the car to the max I run sport+ mode which really makes a huge difference. It does make the car feel like it has much more potential. That could be attributed to how "detuned" the car becomes when it comes to shift speeds but honestly I prefer it over stock.

D Mode: Slower smoother shifts (granny mode)
S Mode: RPMs hold longer

Sport: Increased throttle response and quicker shifts (high performance / spirited city driving)
Sport+: Drag strip / race mode

Many thanks! Very good overview!
Is the difference in shift speed between Stock Sport and xHP Sport (not Sport+) really appreciable?
Do Sport+ shifts feel (subjectively) safe...? Do you feel a kick?
(I have test-driven a (stock) BMW M135i.... it has a different gearbox, but in sport/sport+ the kicks during shifts are really severe!! I was really surprised to feel such an aggressive shifting and such a difference compared to my gearbox.
And last but not least - what makes Stage 3 more appealing to you than Stage 2, assuming you have tried both?

Dont remember
Yes, i feel a big kick when going from 1 to 2nd gear. I don't use it much, probably because I "know" it isnt mean for daily driving
I never tried stage 2 I went straight to stage 3. That was just the recommendations I read in my research

I find shifts in drive mode + sport+ to be very uncomfortable on stage 3, and they scare my GF. S mode and sport+ is nice though.

[Skyhigh]

In what way?
Is it the same in Stage 2?

[Abzynthe]

I've just flashed stage 3 on my gearbox. Anyone have any suggestions of tweaks over the OTS map?

Ive only driven about 10 miles and if I'm honest, it doesn't feel hugely different at the moment. Shifts are probably smoother in comfort and shift are marginally faster in sport.
The main reason I got it was because my car would try and sit at about 1k rpm and this would cause the car to chug when accelerating after cruising for a while. It now seems to sit at about 1100rpm, which is better, but I'd like it to go up another 100rpm or so.

As per directions you need to drive with no WOT for about 100 or so miles for the trans to adapt after the initial flash. During this time shifts can be a bit funky as everything adapts and sorts it self out. Changing settings and re flashing does not require this adaptation process.

After you put on that 100 miles driving slow put it in sport + and trans in sport. You will definitely feel the difference. It’s pretty crazy when it shifts. Also try manual shifts as they are even faster.

What exactly are you looking to tweak? Most people just flash and are done and don’t mess with it.

If you are dme tuned as well “start in 2nd gear” is popular to enable.
