The sad thing is I'm old enough to have actually used that code on the NES version of Contra.

That definitely was fulfilled, however not among other excitement and improvements in the car. I've let the car adapted already, so other than longer term adaptations on the transmission, it's safe to say none of this is placebo.

TLDR: Updated from 2020-March to 2021-March vehicle software, X3M much improved. OBD unlock not affected

The car feels more refined overall, maybe a tiny bit less edgy, but overall it improves the driving experience.

Big key improvements
  • Lane keep & ACC now behaves like you would expect, pingpong is much less, and car is much more reactive on corners.. no more "uhh is the car going to follow this corner?"
  • Lane keep now works during the day where there's less contrast on lane markings
  • Delay from a slow rolling start <1mph but not stopped is fixed, no more hesitation or a small clunk if you roll into power a hair too quick for the transmission to react
  • instrument cluster doesn't crash anymore if you use the konami code on the M buttons for loud starts
  • car doesn't seem to always want to idle high when the cats are cold
  • idrive much more responsive
  • Suspension damping feels a bit more controlled
  • Shifts seem more buttery
  • Only con here is.. steering feels different.. unsure if it's better or worse. There's a bit of off center lightness now, but when loaded up it feels better. I think BMW tried to make it feel more natural, but I've grown to enjoy EPS steering with a tight on center feel.. will need to give it a bit more miles to really know. Sport+ seems to be slightly more usable
Appreciate the info.

I also noticed on my new 20 x3m that the transmission downshifting seems much more laggy compared to my previous 18 X3 M40i even in sport modes.

And then in sport modes it forgets to upshift one you're cruising.

Wonder if this istep fixes these.

Would a 2021 X3 M comp currently being built already have this upgraded as standard... ? Or is this iDrive 6 specific... ?

With the amount of money we pay for these nice machines, we shouldn't have to ask for this stuff huh. Wouldn't you agree...

I never did an intermediary step with newer 2020 firmware ( would be installed on 2021s built early this year and last year ) but I suspect 2021s will get most if not all of the improvements i mentioned.

I had this update done remotely by one of the more prominent coders (Henwee on IG). Took about an hour start to finish and cost about $180. I did full screen CarPlay separately myself. I have noticed incremental improvements similar to those OP described, but I can't say they have been as substantial in my eyes. Given the low cost, I'd still say it was worthwhile. Keep in mind if you're coded, you'll have to recode. My BM3 flash was unaffected.

I'd be hesitant to have the dealer do it if you're concerned about preserving OBD unlock capabilities unless you have a good relationship with your SA. I expect they will simultaneously update DME software (if you have an update) which means no more flashy flash.

You could still have that bench unlocked.

Nope. Post June 2020 DME software cannot be bench unlocked.

Asked my SA to run my VIN to see if I qualify for this 9/2019 build. No dice, he said no software updates show up for mine outside a navigation maps update. Bummer...

Can you please clarify which vehicle would get their DME locked? I have a 2020 x3m built in sep 2019.

I think you may be confusing how it works. The June 2020 encryption change for the Bosch ECU can not be unlocked. The ECU's prior to this do not get the updated encrypted boot loaders, they're just locked. Someone else can then unlock them again which means you have to go to a tuner or ship out your ECU. If a dealer update locked the ECU when it was originally unlocked then it can be unlocked again.

Thanks for sharing, cookiesowns . Always learning something new on the Forums, and admit I had to look up the acronym to even find out what it stands for [ISTA-P (Integrated Service Technical Application Programming)]. Turns out both of our X3MCs need this so have them scheduled for the near future (both were late 2019 builds). Happy to pay the $180 to get us current from a programming standpoint. Will be interesting to see if we can tell a difference.

Had my winters swapped out today. Inquired about this, and they said thereís no software update and that I need to talk to BMW Genius in sales.

I also tried the phone route, and they said the tech connected no problem.

Candidly I have no idea about how BMW pushes out their software so I didnít press further.

The simple answer is, they don't push it out unless it is a major safety issue. Which is almost never. And that's about the only way you'll get them to do it, if you insist that some type of safety related issue is happening. Like the gauge cluster going blank.

Suspension improvement appeals to me!
Lane keep assist and ACC improvements would be welcome, as well as ability to code full screen CarPlay.
