Trying to bottom out this issue ..

Latest xHP documentation I have ..


states for MHD support…

I am using MHD. What Map version should I flash?​

For most cars MHD offers a dedicated “xHP Transmission Setting”. In all other cases just select “Manual Transmission” in MHD. (yes, this is not a typo)







My question is that MHD for N54 shows xHP options for ATs but doesn’t show that for DCT..

So should I flash MHD with transmission equals manual….or DCT?

Not much changes, just reported torque.

Picking manual trans means the reported torque in the tune is unchanged. This is what I would suggest for a DCT.

A non scientific drive revealed that setting it to manual seemed to work well…

I did twiddle with throttle lag and set it to the mid point..full M1 spec was ok in comfort mode but a bit edgy in sport mode..

I set the xHP shift settings to the mid points on both the comfort and sports settings..

Pleased with how it feels..

Now resigned to either moving the DCT into the left side or using Sports+ when moving quicker as the N54 feels like a steam engine when pulling hard in the 1,500-2,500 rpm range…feels much happier spinning a bit quicker ..
