  2. The absolute cheapest Intake Manifold I could find online, want some thoughts on it if anyone has tried or even seen it before.

    It might be made by Phoenix, but it's not listed on the Phoenix website anywhere. Phoenix has more than 3 types, I listed them above in my post, you can see it on their website. For clarity sake since this thread has anything but... it seems you are using the $1800 alibaba manifold that...
  3. Rear Brake Piston wont go back so I can change the rear brake pad

    I use the exact same tool. Are you sure the piston didn't come too far out and somehow got jammed going back in not perfectly straight?

    Actually... the Phoenix Racing manifold doesn't look like the Burger one at all. Coolant ports are totally different, the front connection is different, fuel rail connections, Etc. From the photos on both sites, not the same manifold at all. However, the one that BimmerNetwork sells for $2,200...
  5. Rear Brake Piston wont go back so I can change the rear brake pad

    Go nuclear and take the motor off the back of the caliper. Couple bolts and then you can tell it who’s boss. what tool are you using to retract it? I’ve noticed with the proper tool you can turn it a couple turns, then it will feel slightly stuck, then hit the tool with your purse and it will...

    Now do that over and over and over and over, lap after lap after lap after lap after lap for 20+ minutes, not just once for 9 secs.

    Technically, 99% of the manifolds have that inner hump because of the oil filter access design. That said, some are obviously not thought through as well and come into the airflow more than others. Here is a Wagner (a manifold I have shared a ton of data around) for reference: As usual, I'm...
  8. BM3 Custom Tuning help

    Except that is not the proper way. I literally showed stock turbo datalogs for the before/after above. You also have a MT, so all the clamping, line pressure, and torque convertor talk is meaningless. There are however, many KSU tables (clutch-slip monitoring / protection) shared between AT and...
  9. BM3 Custom Tuning help

    TCU consumes reported torque from DME, TCU decides line pressure, clamping force, converter-lockup, etc based on reported torque from DME. If the car is actually making more torque than is being reported, the possibility that the TCU isn't giving enough line pressure/clamping...
  10. BM3 Custom Tuning help

    Here is a visual diagram, created from the official BMW SwCalDocs, that shows what KF_MDIOP_1_TQE influences. Clearly showing that the TCU is a consumer. OBD PID for the reference torque coming out of KF_MDIOP_1_TQE: PID 63 (Nm) Other noteworthy PID's: 61 — driver's demand engine torque (%)...
  11. BM3 Custom Tuning help

    Okay. If you want to continue to argue with actual official bmw documentation and actual experience from tuning hundreds of AT BMWs, have at it. I just won’t.
  12. BM3 Custom Tuning help

    The load to torque table Z values are inner indicated torque, in Nm. Inner torque is the gross torque produced by combustion inside the cylinders: the torque the expanding gas exerts on the pistons, before any mechanical or pumping losses are subtracted. It's a pure thermodynamic/combustion...
  13. BM3 Custom Tuning help

    Don't just increase the last column in the load to torque table. Great way to get transmission slip if you are making any power.
  14. Stock Turbo BPU++ HP record

    No, and as usual, anyone saying otherwise is lying. E50, stock turbo, 19.8psi flat.

    @lucky phil is an absolute fucking moron that hates everything that others do, and for some odd reason butts himself into conversations he isn't a part of. Then states mental health is a good thing? Absolute nob and probably 40% of the reason I left this shit hole of a forum. He is basically...
  16. Razorlab - 2020 LE build thread

    Getting doxxed by a member and the overlords of the forum not giving a F was the final straw. IG: https://www.instagram.com/early.apex/ I also generally need to take a step back from the online shenanigans and focus more on my real life.
