After some search bar looking there seems to be very little discussion on transmission tubes for the f30 8speeds and above. I just recently flashed my 340i msport and something seemed different than I was expecting. I've reset my setting and flashed again. I will test it again tonight.

Going through the forum to see if anyone else had similar problems I couldnt find any so I want to start discussions on the xHP flashtool for the 8 speed guys.

Do any of you use it?
How long have you used it on what flash setting?
How many miles does you f30 have?

Basic things to get a nice sample base for others in their research.


I myself have noticed in stage 3 it seems like my shift speed is slower in sport+ and there is a delay in the manual mode using paddle shifts. Even after driving 50 miles to relearn it felt like I had smooth shifting switched on (I've checked and it wasn't) but they definitely felt slower.

Everything else has worked perfectly, including the shift speed in sport+/sport mode. It just seems to be in manual shifting that it's slow
