My M5 is back with a new BMS Stage 1 swagger!

Here is some information that might be helpful. I am attaching a link to a brief and rough video explaining how the BMS stage 1 gets installed. Yep, no academy award here but hopefully helpful.
My friend, a trained BMW tech, installed this in about 30 minutes. If I tried to do this it probably would have taken at least an hour because the sensors were a little hard to reach.
I am also attaching a screen shot of the BMS tool from the install screen when you prep the juice box so you can see the settings. We followed the BMS recommendation and I am set a 3 PSI. A few other settings to address but the default is what we did. Hope this helps. Cheers.

Thanks, @Mscarpa, it's kinda frustrating because I had it put in, took it for a 5 minute spin only to drop it off at the dealership for the exchange of my warped brake disk and the exchange of the sway bars for the DINAN ones.

Hence, I probably should be patient until I get real testing time next week.

How about the added boost. I have read some crazy numbers, Burger itself of course strictly stays with the official data of 3.0, 3.25 for high flow and 93 and up to max 4 for race gas. But I have seen some claiming 6.5 PSI over on 93 octane. I wish there would be a chart of PSI vs. improved performance vs. increased risk of damage to the engine.

The friend who installed my BMS really felt strongly that sticking around 3 / 3.5 is plenty to add to the already
Powerful engine without risking damage. I am taking his advice and am scheduled to get the M5 on the dyno next
Saturday and we will see...

Without any concrete data i.e. Dyno, Vbox, 1/4mile runs to prove; my car has felt faster with 3.5 boost 93 octane.

Mike my Juice Box screen looked different will try and post.

I think software to download corresponds to the box sent. As you can see my future use was set to 0 instead of 1 which I changed. Not sure what the other setting waste gate etc are for or what the ideal setting may be.

I have a CP but from my testing 3.5 gives the best performance . When I attempted to go higher up to 3.75 and 4 the tq increased down low but the car pulled power after 6k even after it was fully adapted . Trust me 3.5 with DP's , intake , and 93 octane is plenty fast !

@JPMD
Yeah, you are right and when one buys the Stage 1 they need to check the numbers on the JB and then align to the right software set up as per the attachments. All found in the installation guide.
