@1mrocket5 is my personal please hit me up for all your needs @baskispeedworks @ecmtuner @n63intakes @Bimmer_engineerx And personally anybody wanting help with xhp I am willing to help. I service all bmws now. I have studied many things and now I am producing world class results. This did not happen over night. It’s called consistency. Ethanol wise. It’s a e40ish map currently on the car no meth. I have some great endorsement parts to come after the stock 9 second time is down. Come to find out. The m550i is more like the m5 than you know.

I know that the 2020 plus models got bigger turbos that can go up to 25 psi. I didn't think a 2018 turbos could even create enough boost for that type of power. The 2020 plus also have the rods from the f90, but not Pistons. If you're working on the ram channels with bm3 that's a good thing, they have them from m cars, but they don't have them for our cars. I thought Sergey only worked on old 550 (N63R) models. Halim is a whole different story, he's considered the crown jewel in BMW tuning. Obviously him and Utku focus on the M5. |

Please message us for anyone actually interested we will continue development !
We have taken the years to get this development where no one else would spend time. Lol, there's a huge difference between a mid 11 and a mid 10 second car (200+ HP for 4600+ lb car with driver)... Ps.. as far as forging will be necessary just like the m5 after 9.9 With all the world class partners on this car. Please stop scaring people with the noelle story I touched on them years back and decided against it. The m550 in general is fully capable don’t believe the hype or myths lol. The car has handled thousands of launches. Last edited by Torettoshifts; 06-20-2023 at 10:48 PM.. |

I definitely see value in configuring/customizing the BM3/JB4 and xHP tunes to work seamlessly together on these cars. The tunes were developed independently and we don't know anything about how much they have ever been integrated with one another. I will continue to watch with interest.

Back to the track with new PS5 tyres on the front. Similar night to 6 weeks ago or so.
Tried XHP drag mode and it stopped the car launching, bogging and then going which hurt times. Attached is the last and best run. It spun the rears going into second the changes are so brutal. xHP probably gives me 0.1s 0-100 and about 0.2-0.3 on the 1/4 mile. That's it until it gets tuned in December (warranty expires). Oh and weighed the car at the track. 1920kg with 1/4 tank of fuel. Heavier than what BMW reckon which is no surprise. Last edited by choppedliver; 07-12-2023 at 06:39 AM.. |

I appreciate that. At this it stage I don’t think we will get much improvement from XHP tuning.
I’m sure a tenth or 2 is possible from launch to 3rd gear but it’s not something I’m willing to chase right now as I can’t test the car on the street (it’s possible, but risky and there are few places). I’d be more interested once it’s tuned. I’ll probably just do a BM3 OTS flash initially and then fiddle with xhp to see how deep in the tens we can go. My local shop are BM3 experts and tune hundreds of cars including many BMWs of all sorts so they will do the bench unlock and I can then flash the tune. I’m not sure how expert they are on XHP though, but it’s clear to me that the ECU and TCU tunes need to work together for optimal results. That’s when I’ll need help possibly. I’m in Australia so that means I may need to look for local expertise anyway. Last edited by choppedliver; 07-12-2023 at 06:09 PM.. |

My friend you are moving in the right direction. Don’t worry man I’m working all over the world. We are working on the soft which is the only thing we need to hit 9s while still being in stock form. We have to take it a psi at a time while the ram channels we didn’t have up for up top power are made.
We also have 2wd almost done and then we can provide. It will become very accessible to hit 9s very soon. So don’t worry it will be possible! |

How are the downshifts with the tranny tune? Stock they are terrible and i hate it. Half ass throttle blip. Will the downshifts vary in aggression with the 1-3maps?
Also. Whats the base trans tune package for? Do you need the second package? Keep in mind, i dont race. Purely a highway missle. |

M550bernina, or anyone with xHp I have a question. After xHP flash, i noticed that in sport mode my shift are too harsh and not so fast. It feels like while shifting I have 2 kicks. Like torque pauses for 200-300ms, and than goes huge kick in the transmission (not from the wheels 100%) So I'm curious did you guys have the same, or that's just my car having problems? I tried to add torque reduction +10%, which helped for a bit, but not solved these bad kicks. I had xHp on prev cars, or compared with friends, and nobody has that kicks even in drag mode. But don't have another m550i to compare. p.s. I'm running 2019 m550i (tu3) st1 bootmod st3 xhp best times for now is 3.16 0-100 km/h 7.21 100-200 km/h 10.99 1/4 mile |
