Xhp Transmission tune for F85/F86 now available

[MBoss_F86]

I did MHD Stage 1 93oct tune first and then xHP Stage 2 TCU tune to support increased power from MHD tune

Did my tune first, then xhp. All i have extra on xhp setting is the line pressure increase checked.

Can you shed some light on what that will do for you. I was under the impression that I only need to adjust that if my clutches are losing life. Thx

I'm running BM3 Stage 2 tune with HFC downpipes and just ordered this XHP tune, I think i will be running stage 2 XHP and will adjust some settings in there... I just ordered it today so hopefully tomorrow it will be available for me to flash.... can't wait.

It says it on there to adjust it in order to prevent clutches from loosing life. I guess higher pressure prevents clutches from slipping, especially for tuned cars with more power...

I've had this xHP tune for at least a year now and from what I could feel it deff makes power like crazy and once I switch the line pressure on it was night n day I'm good way but it's cold here in New York and I could deff feel trans isn't shifting smooth when cold almost like don't wanna shift until hits 3-4000 rpm which u don't want to be doing while truck is cold.. o my way I help that is to keep everything in comfort and put in manual but that's also annoying.. it's deff a nice upgrade and I'm going to leave it on but I could deff tell there's trouble ahead lol only setting I messed with is the line pressure and running stage 3 with stage 2 bm3 catless dp and truck is a beast

Bringing this post back from the dead. I have a X6m F86, on BM3 stage 1 and just uploaded the xHP transmission tune yesterday. I ran it stage 2 with a little spirited driving in sport+ mode. The shifts are lightening fast. Very recommended.

XHP released the Max-performance feature https://www.facebook.com/xhpflashtoo...fVeu4Ba67ZcgQl , this feature is already available for F85/F86.

I cannot compare the difference before this feature was released, because I installed the Stage 3 v1.2 (no custom settings) directly from the OEM setup. I knew the XHP from my other vehicles, so maybe I was expecting too much. Before install I was driving my F86 on D2, which was very satisfatory and gear changes lightning fast already while still very comfortable.

Now using the same D2 I feel with just less throttle the car wants to downshift more providing harder acceleration and I had to recalibrate slightly my right foot for a comfy ride. My car makes the OEM power and has less than 20K KM, I cannot state if the F86 installation was worth it or not comparing the F25 30D or E71M, in which cars the improvement was so huge and now I cannot imagine going back to the lazy stock TCU programm.

XHP released a new application version with a new user interface recently.

When I was testing it, I noticed a new version 1.3 of Stage 3 map became available 16th of May with "Improved Launch Control for high-power vehicles > 700HP".

I flashed the Stage 3 map v 1.3, with my car having the OEM power, I haven't noticed any change against the previous v 1.2. I didn't put any custom settings except disable start/stop, which I had previously disabled using BimmerCode anyway.

After few weeks of using v 1.2/ v 1.3 compared to OEM, the Max-performance feature is noticeable and I got used to it. When cruising and sudden accelration is needed, the quick press of accelerator (30-80%) seems to produce slightly harder initial acceleration kick (like if the table of accelerator pedal angle is transformed to a higher throttle opening angle / valvetronic lift) and shifting process reduces the torque delivery slightly less.

The full accelerator push or kick-down made kind of hard acceleration on OEM settings already.

Don’t throw me under the bus guys.

I currently own a dinan throttle booster.

How is it compliant with xhp ? No more need for Dinan ? Useless and/or dangerous using both ?

Thanks a lot.

Took about two and a half minutes for everything which is nice. No fault codes after, about to go for a test drive...

Attaching a VERY useful features in XHP, quickcharge pressures and times. Very nice to see this to see the condition of the clutches in general and current adaptation values. Mine looks pretty darn good after 44k miles.

Ive got a F85 X5M with BM3 E30 stg 2+ custom tune, stg 3 xhp trans tune, dinan intakes, downpipes and pushing around 700 awhp but haven't dyno it yet, I'm waiting for stg 2 pure turbos to come in, its got around 32k miles on it or 49k kms, so my doubt is the following, I was messing around with XDelete making it rear wheel drive and it was working fine, then when i wanted to do a pull against a CLS63s, I put it back in AWD, but when I was going to launch, the rear wheels started spinning and a transmission malfunction light came on, I turned off the car and back on, it went away right away, no dtc codes were found, but I noticed the car is not pulling as much as it was before, the car is AWD for sure now, Turbo PSI is going up like its supposed to up to 21.5-22 psi, but the kick when the turbos spool doesn't feel like before, so basically ive got the AWD "map" with the RWD power for some reason, so I checked my transmission adaptation values but can find much information about it, if my values are good or bad, if its bad, what are the approaches to fix it, I believe it can be my Clutch A, thank you guys in advance, any information will be much appreciated.
