Tried resetting all parameters and doing an emergency reflash but same results.
Went back to bm3 trans for the time being as That scared me pretty good.
No idea what you were doing, but this never happened when I flashed.

Bm3 trans?

Exactly which car do you have, and how exactly did you try flashing xhp?

Thanks for the feedback!

I went into the app and clicked on "send logs" and the app automatically sent them to support@rbttuning.com

Should I also send a direct email about this?

Why would you not want more line pressure when you need it? Is there a risk of blowing seals, or causing internal leaks?

Just wondering.....thanks!

2015 435i 8speed auto transmission. So I'm having a grinding noise coming from the transmission under heavy throttle. 1st,2nd and 3rd gear. Almost like the transmission is struggling to keep up. Under normal driving there is no noise. Any ideas what my be the problem?

I bought this app a year ago and love it , worked on my Samsung galaxy 7 tablet great with bimmergeeks cable. Went to re use it today and it said not compatible anymore. So I got the new adapter for my Moto G7 power phone and it loads great but will not connect with my bimmergeeks cable like before.

It says " can not connect "

The build date on my car is Decemeber 2006 (2007 335i).....it's got the first version of the TCM in the transmission.

Will a v3.0 version of xHP be available for cars with the early versions of the Transmissions Hardware/TCM?

Got the same TCU, mines January 2007,

I asked RBT-Tuning and someone there said yes, they are working on it. Then I got another saying no guarantee they will release v3 maps for the older TCUs, so I don't know what's going on anymore.

We are all working intensively on getting everything ready for the upcoming DCT support, so we cannot look through all the forums as regularly as usual.

Regarding the "line pressure Bump" feature. We created this feature for customers who have slipping clutches due to their high torque tunes. Up to this point, we do recommend to have your transmission fluid already changed and the mechatronic seals and sleeves replaced, as they also start to leak pressure with age.

If you do not have either slipping clutches or a tune with at least 40% more torque than stock, then there is no reason to use this feature and stress your components unnecessarily.

Should you still blow an old seal, then it is easier to replace all of them with fresh seals, together with a fluid change, than to change out a burned clutch pack, which should be the main concern at this point.

Thanks for the info! I'm pretty sure that anyone running the MHD stage 2, or 2+ tune is going to be over 40% more torque than stock...which comes out to around 420 ft/lbs.

Question

I'm running a stage3 xHP tune on my 07' 335i. I like the way it shifts, but it still feels like the motor is cutting power a lot as it shifts. I'm assuming it's pulling the timing back and/or closing the throttle body for a spit second as it shifts to put less load on the transmission?

Is there a way to dial some of that out? Would the line pressure bump option help? What about playing around with the Torque Reduction on Upshifts settings?

It just feels like it's giving up a lot of power when it shifts.......

Anyone else have that issue?
