After spending some time on the forum, maybe this should be moved to the "Advanced Tuning" section? Sorry for any trouble...



Hello, I'm new to the forum but not new to N54's. I had a 335i from 2010-14 and a 535ixT 6mt from 2014-present. I am an engine calibration engineer by trade and was looking for some help to tune my own car.

Coming back into the scene after a few years of forum absence, it seems a lot has changed for custom tuning solutions and I would love some help in clarifying what's available.

The only ones I know for sure are end user tuneable are the Cobb with Race Software and a custom wired Motec M1.

Now that I have a xDrive car, I'd also be interested in any tuning solutions available for transfercase control, if there are any.
Example of this concept available for the GTR: http://www.linneytuning.com/product/4wd-controller/

Very excited to join this forum!

This is my old 335i:

Very interesting, thank you for the direction and help!

I actually spoke to xHP and it looks like currently they only have awd on/off capability now, but they are working on the full functionality.

MHD for custom tuning. You can self tune flash only or stacked with a JB4. Work off your original bin for flash only and a BMS BEF for JB4

You could also run MHD OTS tunes (stage 1, 2, 1+, 2+, e mix) but those maps are locked and not editable.

welcome to forum , by saying awd on/off means we can convert an awd car to a rwd by tuning solution ? If so, that’s unbelievable!!

Thank you! Yes, my understanding is that xHP has that ability through calibration/tuning.

MHD for dme, tune with your factory bin or any base floating around for your particular dme using the matching xdf (definition file with known public tables) through Tuner Pro.

XHp for trans in the same way, there's public xdf for the trans, load with your trans bin file into Tuner Pro and go ham.

I mean do you think it's worth it to play with the xhp XDF or the module is pretty much all the options you need

I think customization is a must with pd trans as I can hold alot more torque on shifts now. I just don't know if I could do even better with making my own map with public xdf

Would be cool if the x delete was a button on the steering wheel so you can hit the burnout box then launch in awd then back to rwd in 3rd

Yes it would. That’s why the new M xDrive cars have that button. It’s cool.
