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.

I didn't realise it was 100 miles. That will probably take me a month to do haha.
I've had a little play with it today and made it shift sooner in the low gears changes by a few % and raised the % on the change down on higher gears just to keep the revs over 1000.
The main problem I was having was that when cruising along at 30mph or 70mph it would be fine, but if I were to accelerate, but not enough to kick down, then the car would lug and judder until it got on boost. I want to eliminate the lugging. Everything else I'm fine with, and overall I'm quite happy with the new map.

I wonder…. You are installing a new gearbox (or engine) software! Potentially catastrophic effect if done wrongly! Do you guys not bother to at least read the "ReadMe" file a.k.a. Installation manual!?
Just me?

I was wrong, 50-75 miles. You shouldn't be changing anything during this time.

Straight from XHP's FAQ:

Do I need to do a run-in-phase?
We do recommend around 50-75 miles of driving without wide open throttle, with varying speed, load scenarios and shifts, so the transmission can adapt to the new software as fast as possible.
This driving-in-phase is only recommended after the initial xHP flash and not needed for subsequent flashes, like map changes or different custom settings etc.

I just flashed my transmission, but the shifts are bad.
Your transmission may behave weird, right after flash, e.g. starting in 3rd. gear. This issue should clear within a few hundred meters of driving. The transmission has extensive adaption-algorithms, to keep shift quality in check over a full life time and even with heavily worn out clutches. The adaptions applied are very sensitive to abrupt changes, as they operate in a narrow window. Therefore, shift quality can suffer in the first few hundred miles, after doing an oil-change, replacing transmission hardware, or changing the TCU software, like with xHP. Don’t overstress your transmission during this adaption phase. The best way to adapt your transmission, is just normal driving in D mode with lots of varying speeds and shifts. We DO NOT advise anybody to clear the adaption values to speed up the process. Depending on the current wear state of your transmission, this can lead to unwanted and permanent bad results.

Xhp Drag Mod mode test. On the street + 15C. The road is simple asphalt. Target 28 psi. Tim 17. E35 / WMI Port. Start from 2nd gear 3000 rpm. The total weight of the car with a driver is 1720kg. X-Drive.

So a .3 improvement on 1/4 and (5kmph) negative on speed, am i seeing that correctly?

Just curious to check if there is any failure in regards of this xhp tune

Haven't read of any. I've ran it for many years on my M235xi and M240xi and drive hard, combined 40-50 thousand miles driven aggressively. I am curious about this new drag option as it sounds great, just would be concerned about how brutal it is on the transmission life span.

how many years have you run xhp tune?

I assume all F3X series use the same transmission (all engine type)?

Thanks.

[Skyhigh]

Much more relevant - how many Kilometers?

I am pretty sure you can safely have any tune for 100 years if you leave the car in the garage

Ok, M235xi and M240xi, driven hard, 40-50 thousand miles combined on XHP, performed normally...

Haven't really tested it like Glemm but you can really feel the lack of torque reduction, car jumps forward on upshifts during spirited driving. Haven't done any WOT upshifts yet.

What is WOT? I only know one meaning of WOT and I don’t think that’s what you mean here ��

Sounds like using this daily probably not the right idea for me.
i guess time will tell on the wear end of it...

Wide open throttle

[Jnat]

I just tried it and wow, very impressive response in all aspects...
Great job XHP
But, i will not be using 24/7 as it's abrupt... which is good

I'm pretty safe then

100-200 3/4/5 gear. Drag Mod Ok.

I've decided I'm doing xhp before I even do MHD. The transmission has a much bigger impact on driver experience than a boost of 10-20% hp. This car so much faster than I can utilize in my DD patterns already that I think the extra 50-60 hp from Stage 1 will be largely wasted if I do it first.

My iPhone Ethernet adapter comes tomorrow

Please share your immediate experience, as I am intending to do the same very soon.

you wont shave off 2 seconds from a 100 to 200 kph with only a trans tune

i like the take off in second gear and uplifted shift rpms in comfort ( ive raised them by 20 percent ) . i dont do 0-60 launches .

I had a 6 speed 128i for 5 years and the ZF in this car takes a little away from the enjoyment right now so if I can customize it to fit my driving style, it'll bring most of that back. I have not once felt like this car lacked power even on the interstate. It'll blow the doors off just about anything. So I can wait a little longer for power mods.

I don't dare to run stage 3 anymore. At a certain point in time the downshifts were so harsh in S-mode and M-mode it was really like banging in the gears, especially from 5 to 4 it was really bad. You could even hear it.
So first went back to stage 2 but that didn't help much, so back to stage 1. Did that for a while and then tried stage 2 again. After another while tried stage 3 but then altered the throttle blips to try and make it a bit smoother. That seemed to help quite a bit however downshifts were still quite harsh.
Last week went back to stock and I will keep it that way for a while hoping for that the trans will re-adapt. Even now in stock the downshifts in m-mode are not smooth (upshifts are), but to be honest I don't remember if they ever were?

However I don't know how long I can live without the custom shift settings for comfort mode. The ridiculously low shiftpoints drive me crazy. I don't understand how people can drive like that...
