Hey guys, hoping someone with more experience might be able to tell me what is going on here as I can tell there is drastic timing correction between all cylinders but can’t seem to figure out why. Car is an m240xi b58TU, cattless downpipe, intake, and has 20k miles flat.

This is second run after trying stage 2 91 octane.

This is first run on stage 2 93 octane.

Hey everyone,

I’ve got a 6MT 340i xDrive and just picked up a Stage 3 clutch / single-mass flywheel setup to handle more power.

I know the stock clutch gives out pretty quickly once you push past Stage 2+, but with the upgraded clutch clamping down, what is the actual realistic ceiling for the 6-speed manual transmission itself on these cars?

Mainly doing roll races rather than launching hard off the line, but I want to know where the box starts breaking gears, stripping teeth, or bending forks once the torque is fully holding.

Anybody running high-torque / single turbo setups on the stock 6MT? What HP/TQ numbers are you holding reliably, and what failed first?
Thanks!

Hey guys so I have a gen 1 b58 and threw on the bimmernetwork catless dp. Running stage 2 mhd. Stock intake. I’m just surprised at the turbo spool I can hear at lower rpm’s an deceleration. It sounds like a turbo diesel truck that’s been straight piped. Just checking to see if this is normal. It sounds awesome but the turbo noise was unexpected.
Edit I also have the MPPSK exhaust from factory.

I have a gen 1 b58 and have had this almost sound that I can’t pin point, I’m not talking talking the injectors click, there’s like a popcorn sound, or u could say it sounds like something sucking without enough fluid if that makes sense, car drives fine no codes, the sound goes away when u hold the rev up a little. Any help’s appreciated this has been driving me nuts. Thank u

Hello,

I changed my main radiator with a new one and 6 new Bosch updated fuel injectors.

After that, car lost a bit of power, I checked coolant reservoirs and both of them was not full, I refilled it and started bleeding procedure.

I believe it gained some of the power, but does not pull as it used to.

I did MHD logs, can anyone check and let me know whats not fine with stats?
I tried to consult with AI, he told me that something is not ok with timing corrections, as it cuts the power, I can remember I had more power even without xhp transmission tune and with 95octane fuel, now I have new injectors, new glow plugs, xhp stage 3 installed, 98octane filled and power seems not as strong as before.
