LFX E39 Tuning with HP Tuners
There is info on this spread out across multiple build threads on here, but I wanted to consolidate it into one place for reference and questions/answers. I know a few of you guys have already gone down this path. Please post up any tips or resources you found helpful. From what I have read, tuning this engine is a bit difficult.
Saw someone post this up and it explains why the E39 is a bit more complex than most ecu's. Good primer for what you are getting in to.

Just got an HPT MPVI2 for $372 on Amazon with 2 credits included. Seemed like a good deal.

You should only need to disable VATS to get the engine started.

Once you get the car started, you'll have to start logging data. This is where you need to turn to the HPTuner VCM Scanner software. There's a ton of information out there depending what aspect of the file you are trying to tune, but this will get you started with how you want to set up histograms and configuration files.
