Latest ISTEP update transformed the car
So I just finished installing the latest ISTEP integration (firmware) on my car. It was done with ESYS in one full swoop I went from a late 2016 build to v61.4
Many modules were updated. Including FEM_GW as well as the DME and DSC and GHAS (differential) I haven’t driven the car in Euro MDM yet but on regular MDM the car is much less intrusive when it comes to DSC kicking in. In addition it feels like the diff works slightly better to balance the power out. As if it’s way smoother on lock and unlock, putting down power better. Steering fees a bit tighter and there’s less dampening so you feel more road which is great. Haven’t tried F87CS mode just yet. The most notable change is the responsiveness of the motor, now it feels like it just pulls, and the transition between shifts is much smoother. The throttle is way more responsive and the wastegate has also seem to be adjusted to where the car feels like it makes boost quicker. Then the pops and bangs man, sport and sport + sounds closer to the hidden traction mode. Pops and bangs are way louder. Apple car play also seems to be more responsive, when quickly shifting between ignition modes it used to kick the phone off and it won’t reconnect until after the car goes into sleep mode. Now it re connects after a brief wait and the interface is much more responsive. Overall it’s worth a shot to get the dealer to update, if anything well worth the $150 dealers usually charge. PS: if anyone wants this done to their car I can help ya out given that you’re around the OC area. You’re just gonna need a spare car or a battery supply in order to give it constant power Update 2: It seems that under certain circumstances the car goes into the ZCP/GTS Startup roar mode.. I still can't find a way to get it to reliably do it, but it's happened more than a few times already.

Never heard of so many changes done for a firmware update. If all of this is true, then it should get some mention in the media.

This is interesting, is there a tutorial on how to do it with ESYS?
I take it the SP-Daten/PsdZData files cover all cars, EUDM and USDM? Last edited by DoZZa; 07-30-2017 at 06:25 PM.. |

Yes, all BMW dealers can do this as they all use the ISTA diagnostic and programming system tools. Ask for the i-level update and they will likely charge you perhaps $150, and the car probably needs to stay overnight because of their extremely slow (technically dated) update system.
However, if you can find a problem with the car, then it's free. Car software updates are not provided by BMW under warranty without reason. The car needs to either have an ISTA/D diganosis indicating a problem with the car that requires new firmware, or an active TSB (Technical Service Bulletin ) that requires new firmware to resolve.

I'm definitely skeptical that the car performs noticeably different after a software update. However, if true, this could be a move by BMW to keep the 2018 competitive with its rivals like the rs3.

Especially after a LCI the software usually takes a big step and have done so for the last couple of generations. I always try to get the latest software after a LCI. |

Yes, you need Full PSDZ V61.4 Also, I updated the original post, but it seems that the ZCP/GTS startup roar is in the latest I-STEP... I can't figure out a way to do it every time just yet... but it caught me off guard a few times already/

I doubt that nothing more than the adaption values were deleted and the car 're-learned' a driving style now... which is you pushing it harder.

I don’t think anyone expect it to feel like a new car, more like a refinement that can definitely be felt. |

There's a way to get your NBT version and you can cross reference to I-STEP, but the easiest way is to throw it up on ISTA+, or get a print out of the dealer key read with ISPA Next
