Well if no one uses manual mode in comfort, why did they botch it? If I need to pass someone quickly while cruising I always shift into manual mode. Now I have to switch to manual and sport+. I'm more pissed about manual mode not staying in 2nd. Still don't feel any aspect of the stage 3 flash was worth it.

I also noticed the reduction in the blap blap sound on shift, however after listing and review the logs i think they re still there but with the short shift duration they are just much shorter in duration and therefore much less noticeable
that is why you still notice them in comfort, but in sport + they are almost gone because the shift times are faster basically they are extreme timing pulls that is used to reduce torque during the shift and not stress the clutches, so faster ships mean you have less of a disruption in power and therefore less time to fart explosions our your exhaust ports, you go faster but in less style lol if you look at the logs you will see that the time window the timing is pulled and power is reduced making the blap blaps is reduced form about 250ms to about 100ms with XHP in S+, so it would make sense that is is much much less noticeable |

Does anyone know what the adaptation values exactly mean?

I do not. But I know they didn't change as a result of the flash either.

Adaption values shows tear and wear on the clutchpack, the higher the more they are worn.
As I got it explained from a BMW tech it is a number for, how much force is used to hold the "clutch" to prevent slip. Clutch in "" since there are no clutch in our tranny. IT works by oil that changes friction when it gets hot.

Has anyone got any draggy back to back runs showing benefits from the torque limiters being raised?

I've searched for this answer prior to posting, so my apologies if it's been discussed, but does the xHP allow 8th gear in Sport Mode? I have a pre-LCI F34 that locks out 8th in Sport. I prefer the driving dynamics of Sport mode but would also like to use the full range of gears, especially on the freeway at 90mph without switching back to Comfort.

Flashed stage 3 and sort of blow away by how the car has responded in s+, love it!
However, it tends to shift even earlier than the stock map when in comfort and sport. I have seen a few other people cite this as well. Would love to hear any thoughts/experience on how to mitigate. Has anyone had success with reverting to stock shift maps or using the shift map editor? Read the latter can be a mixed bag... Thx |

At first when I flashed to stage 3 I noticed how the tranny wants to hold on to the gears longer after I shift in comfort and sport and it really bothered me, I couldn't figure out why it was doing it so I tinkered around with the settings a little and saw some improvement but it didn't solve the problem, I kind of gave up and learned to live with it.
So now I drive in manual S+ or auto comfort and nothing else. I saw other people mentioned the up shift farts and idk if its because of my dme tune (mhd) settings with the downpipe and MPE but the farts are definetly there and extremely pronounced in sport+ to the point where I sometimes shift in high rpms in the lower gears just to hear them

Xhp newbie qn....
With the torque limit does it mean once u mods exceed the limit, youre wasting money modding beyond that? Does xhp allow to remove the limiter but keep stock mapping? Thx |

No. XHP allows you to alter the torque limit in each gear, so you can upgrade the engine output and the transmission won’t hold back the extra torque.
Yes, torque limits can be removed (raised so high they aren’t an issue) whilst retaining stock shift maps. |

Running stage 3 flash and like it in most ways.
I think I need to understand more of the settings though. I feel like with car in sport mode(transmission D) it's just hunting for higher gears too quickly. On partial throttle acceleration (~50%) it just shifts much quicker than I'd like. |

Nope. You can set the limits yourself in Xhp. From the Xhp manual... "5.11. Torque Limit per Gear Especially on high power RWD cars limiting torque in the lower gears can improve traction and make them easier to handle. xHP offers a range from 300 Nm (221 ft lbs.) to the possible maximum of 1000 Nm (737 ft lbs.) for each gear. It can be used either to limit boost in the lower gears, or to limit the engine power overall in all gears to protect the drive-train components. The electronic limiter works by sending a request to the ECU (Engine Control Unit) to lower torque once the limit is reached. The ECU then takes the necessary measures (close the throttle/lower boost/lower timing) to stay steady on this limit. It's the same method applied during shifts, when the TCU (Transmission Control Unit) also takes over the torque control from the engine to enhance the shifting. This method of control works steady and within split seconds. So you can set the 'limit' far higher than the engines output, so it is not being limited by the transmission. |

I just drove 50 miles in comfort "D" and XHP adjusted to my driving.. down shifts really quick when I give it a little gas before I even notice it... seems like it's always in the right gear..... but today I put it in sport "D" and like it totally forgot how I drove... so we'll see as I start playing with it more now...
chinniciF32 ... Yea I got very pronounced shift farts too...lol.. |

Out of curiosity, why do you choose these limits? Why not remove all the nannies and drive around wheelspin issues etc? I have mine all set to max.
