xHP now available for M550i

I’ve only been using it for like an hour, so no direct feedback at the moment, but with an 82F ambient, I bested my 0-60 time by .02 seconds (which was done at 59F). Drag Mode was toggled on and no other changes at the moment, but when the temps drop tonight, I’ll include some additional results.

Curious to see where you end up! I think I might pull the trigger. Definitely want to hear feedback.

Did some runs this evening and forgot to flash some additional changes I’d made, but….

Improved my 60-130, 1/8, and 1/4 times

60-130: 8.89 (9.02 previous)
1/8: 7.23@99.17 (7.47@98.81 previous)
1/4: 11.18@124.72 with a 1.75 60ft (11.29@124.23 previous)
0-60 best is still 3.30 with a 2.04% slope

Ambient: 64F
DA: 711ft
Elevation: 38ft

I’ve since flashed some updated settings that I’ll give a go with either early tomorrow morning or tomorrow night.

Car is a 2018. Ambients are still meh, these are street runs, and I’ve got Pirellis for rubber (not gonna swap em to PS4S’ until they’re ready to change). These specific items are limiting my runs overall.

Nice!

What all do you have done to your car? I've got a 2018 as well… BM3 93 stage 1 tune and BMC drop ins. Best I've gotten is 3.55 0-60.

Stage 2 E30. Downpipes (ARM), plugs (97506’s). That’s pretty much it heh

I just went through their website. In their "Check Support" section the only M550 engine they are supporting is 462 HP, not the 523 HP for 2020's and up. So it seems no.

I have 2021 LCI and it's not compatible yet
