Mod list looks pretty solid, you're changing it to how you want it within a price point that you want to spend
I did similar as well minus the BPM tune & CG controller. I am more than content with the BM3 valve operation. Efficient is OEM w/valves opening after 4500 RPM, while sport and sports plus are 100% open. |

Personally, I find having an additional valve controller quite useful to shut valves completely off when I want the car to be quiet in the neighborhood and to force fully open when I want to hear the exhaust note all the time or set it to OEM and let the ECU decide. |

I still have my valve controller installed but no longer need it. I'll just switch to efficient mode if I want the car to be quiet.

RE: valves
My 2015 does not hold exhaust valves open all the time in sport+ mode. Valves closes at higher rpm in the bigger gears - not sure about the details but am certain in 4th gear or higher and somewhere around 4k rpm plus, valves close. I have CG precision controller now. |

All the parts came in very excited to get everything installed. I will have before and after dyno results too if anyone is interested. I may order a couple other parts.

In regards to the valves control, i’m using Bimmerlink on my phone that can open and close valves and turn off/on ASD. But I noticed this - on a ZCP car there is a difference between Sport and Sport+ WITH THE VALVES OPEN. I did extensive testing yesterday and can confirm that 100%. After I open valves from the app, Sport mode does become louder, however it’s still not as deep sounding as Sport+ with less burbles. Last edited by AMOR; 05-28-2018 at 04:42 PM.. |

Yes this will be a BPM stage II 18 zcp 6 speed manual. I am engaging the rev matching in sport plus. But I have disengaged rev matching in regular sport mode. I do still like to heel toe occasionally. I opted for gts burbles all rpm. I did not get the extra burble tune. The car is not a daily driver for me so when I drive it its pretty much always in sport or sport plus. The fact that the car has an efficient mode and what it makes the car feel like makes me hate they have to do this in today's m cars. I am considering the BMW m performance coil over spring kit. I would like to tuck the wheels into the wheel wheels just a hair more.
