• 100-200 - I got a new personal best of 5.94s (that's on pump fuel and OTS stage 2 BM3 map)
• LC will now engage 2nd gear by default (this is not customisable in settings from what I can see) - in this setting, I get a consistent 3s 0-60 (2.98s lowest) - before the flash, I got a 2.8s 0-60 but that was a 1st gear launch
• Regarding above point, it does say in XHP app that you need to customise the LC torque scaling manually for tuned cars as by default it's set for stock cars so I probably need to play around with that to get a faster 0-60
• I launched in D3 in 1st gear with DSC off and got a 0-60 of 2.79s (basically just as fast as LC stock, this means even if I blow my 50 launch counter, I can still rely on this to get me a good launch)
• LC now can also be engaged in RWD mode for xDrive cars... Not confirmed as I only tried this once and immediately aborted, I will have to try again to see if it was a random glitch or not.. not sure how I feel about this, I would like RWD not to engage LC when as I use it for warming up tyres
• On Dragy I got a 1/4 time of 10.55 but it was a bit wet and surface not great so I don't think its the XHP tune. I need to try again on the same road and dry conditions as before when I ran 10.46 (pre XHP flash) - I will do that this weekend

When you say it shifts quicker, does it also react faster from pressing the paddle to actually shifting at WOT?

When are these transmission tunes going to start getting implemented into one modification? Flash the ECU, and trans at the same time?

Thank you for the feedback!

P.S.: Last week I saw videos on youtube, that people are LC their G8X Xdrive from 2nd gear and went straight to test it. It is the same procedure, however instead of 1st gear you put it into 2nd and the LC is working without a problem.
Much better start (than 1st gear) and got 2.95s 0-100 kph on 1.64s 60ft.

There is no hard data or evidence. It's just a couple forum members who swear by it.

My thoughts are that if this was true, how come BMW is not disclosing this anywhere? Lawsuit anyone?! You'd think it would literally be in the manual or some kind of official statement. Why hide it and then punish the owners by making the car shift slower?! Never heard any manufacturer doing this.

This on a stock car? Running a dragy? What's DA? Got a screenshot?

Well one flashes the ECU and the other TCU. Not sure it can be done simultaneously

Every other cars that I've tuned, it's just a second file on the handheld.

That would be great Mike. I think most of us are really interested in the time it takes from paddle pull to actual shift. One person on here even sold their car because of the lag in this. During moderate throttle and when shifting before redline, it is fairly quick, but for some reason at WOT near redline, there is considerable lag, which is weird because torque drops off at redline.

I hit the limit on the f90 for sure. Xhp with drag mode gave it back to me.

Not a stock car, but just with PowerBox (Manhart MHTronik). Michelin 4S tires and on normal road.
These are my two runs in both direction on the same road. I am using Racebox for meassurement.
DA was around 1023 and temperature 27 celsius (80 fahrenheit) degree.

I flashed Stage 3 and the car felt slower. I also launched the car once and got a transmission temperature warning on my check controls lol

Accordingly to the owner of XHP, xDrive cars will have an update soon.

Nice! Thanks for the insight!

Yeah I just flashed stage 3 and in drivelogic 3 it feels way too aggressive for the Xdrive system. Damn near feels like the transfer case will break

But have you noticed much less delay from pressing the paddle to actual shift at redline during WOT?

I have. It's QUICK

Nice! May have to pick one up! If any of you can record the shifts that would be awesome. XHP should definitely show a video of this. Everything about this car is perfect but most would have preferred a DCT. It sounds like this tune can get us pretty damn close.

I'm telling you, stage 3 feels like a built dct. I switched over to stage 2 cause 3 was wayy too aggressive on my xdrive system for some reason. But, I'll try to post a pic of stage 2 shifts for ya

That would be appreciated!

Interested, as well.

I just got the green light from BMS to get this mod. They tested it, and they were satisfied with the results.

I will get it soon and post my feedback
