I think i have a theory that this is indirectly caused by cold start noise reduction on catless DPs. With oem cold start, the o2 sensor warmup is "close enough". With cold start noise reduction, the DME thinks "huh, it shouldnt be this hot already, i didnt send enough flow thru yet". The cat...
Looks like it depends on the bolt material in your kit, not the pan material.
ZF 8-Speed transmission torque specs:
Oil Pan Screws - 10Nm for steel screws, 4Nm + 45 degrees for aluminum screws

The lower the wing, the closer the airflow's downdraft matches the rear glass.
The middle of the glass is about 20 deg when you measure with an angle finder. Since your wing is so low, that means the oncoming air will already have a 10 to 15° angle to it.
Giving it another 15° is a recipe for...
Yeah I saw that in your pictures, but I was worried that putting the bolt head directly on the plastic had a higher chance of cracking it, since it took a bit of torque to get off
It certainly didn't help that my initial package, and possibly others in the first batch, got lost at customs. Dec 22 is when customs got my package and it still hasn't been found.
The trickiest part by far is getting the headlight out if you haven't done it before. (thanks to racebred for making me pull the front bumper 5 times this summer).
The following coding changes might be useful to a general audience that DON'T have the DivineDrive intake duct and DO still have ACC, but want to get rid of some annoying warnings:
INTEGRATED BRAKING in ProTool, says VIP CODING in the lower level menu
C_RECW_Vorhanden -> Nr000_nicht_vorhanden...
These instructions correspond to those of you installing the DivineDrive intake duct, or anyone else that is annoyed by the active cruise being overly cautious, even at its minimum setting. Note that ACC can be disabled by holding the "closer" button the steering wheel, but will re-enable...
The Airfoil is everything. In a perfect world, with an infinitely long wing, the 3D results will converge to the 2D. The 2D simulation is the upper limit of performance. AFAIK, a 3D CFD run or wind tunnel can only approach the 2D simulation results. If your 3D CFD run outperforms the 2D...
Seems about right to me. Screenshot was from the occams aero discord

Yep, given a known profile, the 3 tuning knobs you have are span, chord, and AoA.
Increasing span always improves overall efficiency. Always max this first.
AoA has significant drag penalties. Always adjust this...
Based on just visual checks, the zeb wing has more curvature, which means it likely has the similar DF at max AoA as the AJH, despite the smaller chord.
I have never worked with zeb but the vibe i get is that they are very responsive, but you will pay for that response time. Thats their main...
After doing some research, it looks like the seat belt receptacle cannot be jumped with a wire or resistor on Modern bmws.
"The creator tried various resistor values (1 ohm to 2,000 ohms) but still experienced either the screaming seat belt light or the airbag light returning (0:56-1:04)"...
