I want to believe in this claim of additional power. Results look good, but we really need some assurance @Rexpeed. Maybe you can sponsor some willing participants and have them gather unbiased data....

So, you're saying I still have time to get a Valentine's day gift :rofl:

Mine used to come from down there: I put a foam in that cover thingy, it's resolved now. Is that also where yours is coming from?

Indeed

is this added already? I am under the impression that we may see it for MY22. rumors of 11hp bump on WOT. This has been floating: June 2020+ are not ECU flashable yet anyhow :) it'll probably be another table if visible to tuner... gotta look at bimmer forums as many X-suv's already have...

Well, I didn't want to be the one, but hey 2 messages before mine so there it goes: What assurance do we have for buying a complicated piece of product from a company who specializes in body parts... reliability, durability, reproducibility ?

Bunch of 86 owners added hitch to haul set of tires for AutoX but rear bumper had 2 tow hook locations.. If you believe this website, it features a hitch for 2019-2021 Z4, but I think it's generic BMW hitch...but a start.. https://stealthhitches.com/products/bmw-hitch-shr31034

I've removed it with BM3. Fyi, car was pretty stable and felt it can easily do more, which we know it can.

If no sponsor then Amazon at least has it... https://www.amazon.com/dp/B077KKPMTB/ref=cm_sw_r_cp_apa_fabc_W0CKVCQF8PYD2PN1NDYB

With Waze, even at 163mph per tacho, Waze only showed 2-3mph difference. I've also checked at 80-120. around 80 it was 0-1mph, 120 1-2mph... Should have used a more robust tool but wasn't really prepared. It was ~46F out tires warmer. Don't recall the tire pressures...

I suppose they're heat-welding the two tank halves...and judging by the pictures, they're welding top and bottom mold... On September 14, 2020, a non-US field report indicated that a 2019 BMW Z4 experienced a fuel leak. An engineering review was initiated, and the fuel tank supplier was...

:) I believe it stands for on Board Computer. Come to sift thru the Owners manual there is absolutely no Reference to BC. It's like they omitted it like a unwanted child :P They just call it the button on the lever :) Still have the FRS!

Dude, BC button.

I've the MX and this was not the case one time I forgot it attached... I believe some said that their car don't shut off completely with OBD attachments...

If I'm not mistaken after the build of Launch Editions, there was a first update that made it only bench unlockable. Then, with A91 and 2021's past 6/1 it became unlockable.

JB4 is piggyback, meaning you didn't even need to know anything about your ECU. It works on all. BM3, MHD, EcuTek, etc are ECU flash solutions which require unlocked ECU. there are pros and cons to both. if you want to be on the safe side of warranty JB4 or any other piggyback like Titan...

for simple hp improvement, down pipe. cheaper and higher hp.

Well of course on their end it'll be "unlocked" to perform updates. They can't unlock it to be tuned by you. You're better off asking for the ECU date :)

and how big are the prints?
