Read the first few posts and make your own decision!

No hard feelings buddy , she fells it deeper, the exhaust sound

I flashed full i-step update to F20-17-03-505 today from pszdata 61.2, seems like there's more burbling in the zcp exhaust note, not sure about tone. Anyone else running 505?

For the record I was on F20-16-07-502

I am using 61.2 as well. I flashed the euro DME tune on a non-ZCP. Burble amount (or lack thereof...) seems unchanged for me.

Update: Could be that the DME is just relearning stuff, but it looks and sounds like the car revs higher when turning over.

It seems like it still has more blurble and deeper tone but I have USDM zcp

how is it smelling now ?

No strange emissions smells anymore (that only lasted for about 2-3 drives after the flash). Turn over seems normal now too.

Only other notable smell is one of burnt tire, which has been present since day one of ownership lol.

Are you considering doing the euro flash soon?

I would but I am too lazy to take apart so much for so little, unless you can show you gained 5-10Hp, then I'll rush and do it

Racking my brain a little more about the Euro DME flash I first did 5mo ago (and have kept with it in later I-STEP updates), I now recall that RPM matching was improved.

Mind you, I drive a 6MT, and hardly spend any time these days in throttle modes other than Sport+, but I do recall that US DME maps' RPM matching wasn't perfect, but was a small (but noticeable) bit off, ever since taking delivery.

It became perfect after the Euro conversion flash, with not discernible fore/aft chassis movement on the release of the clutch. Mind you, this was rolling on OE wheels and tires at that time, so that wasn't a factor. I'm also talking about the base S55 map, not the ZCP variant.

I'm unsure whether this would "still" be an improvement, as I haven't driven the US DME flash on any software that's been released since December, so perhaps it's already been fixed.

why the **** u gotta pay for an update to your car. thats such bullshit. any way to squeeze this out for free. make up some problems?

You must have posted in the wrong thread! No one here is talking about paying for an update

Since the flash I can detect subtle hints of butterscotch and toasted orange rind, especially near redline.

Jk, I suspect any possible HP gains are within the noise of most dynos, i.e. not statistically meaningful unless you do like 1000 dyno runs lol.

To me, the main thing that changed is the engine "dynamics". Kinda of hard to describe but here it goes... on the spectrum of turbo<----->n.a. engine responsiveness (which I've sampled quite decently in various cars), it feels like it has shifted towards the n.a. direction.

If my understand of turbocharging is correct:
The intake manifold CFM increases when removing the (surprisingly hefty) liners, which (in theory) should provide the turbos with more air to play with at a time when they are air-flow limited (i.e. at low RPMs). The significance of this effect is pure speculation of course....

New to the updating procedures so I apologize if that's standard method when updating BMW's.

I actually thought this too, but I didn't post anything about it because I thought it seemed hard to believe lol. In general I think the engine is a little happier to rev (could be the liners and/or the new ECE)... before the flash, rev-matching wasn't quick enough, even in Sport mode and I'd release the clutch before the RPMs caught-up which would lead to the fore/aft rocking you were talking about.

OT: I just drove the ND miata club (6mt of course). Super super fun car. It will be the next car I buy. Don't worry I won't sell my M for it though.

This might be a good place to ask. Is there anything else that needs to be done to convert EPS settings other than switching the variantencodierng normal options in the FDL-editor? That's the only thing I had changed (from F80_F82_default to F87CS), want to make sure I didn't miss something.

Not really, better post in one of the threads that reference this coding option, search or ask @hakcar. Here we are discussing flashing (not coding) to newer firmware and user's perception of changes

[cloudzy1]

Does anyone know if you need to give your SA a reason to do an update to the latest firmware? I went in for a service and asked if they could do the update and even offered to pay since I know it wont be covered under warranty, he all but refused to do it claiming it was a huge liability on their end. Has anyone had to deal with that or should I go somewhere else.
Thanks

No. If you are willing to pay, they should quote it for you, same as any other service.

Hey all, I took my M3 in for service and my SA said he needs to keep the car over the weekend to change a rear bearing as part of a TSB. Well, I asked him nicely if he could upgrade my software to f020-17-03-502, due to lurching in Sport+ and he kindly obliged! The only thing he couldn't code is the ZCP coding as my car isn't a ZCP. I didn't want to push him since he did this for free. Overall, feels better and sounds better, but I concur with the previous posts on this thread.

Now, if only all my previous codings such as DVDIM and Blinker count can be coded....oh well.

Wow, your dealer is able to code stuff ? You may be mixing things here. Dealer usually use a software called ISTA/P to update the car's software, it's like plug and play. The software determines what needs to be upgraded and presto its done.

What you refer to as ZCP coding, is what hobbyists use Esys to configure some parameters using values from ZCP equipped Ms. Whether that does something or not is completly open for interpretation and varies with many factors. So enjoy your update, and if you want to "code ZCP stuff" for your car, you can ask some sponsors for that or learn to do it yourself

Sorry for the misunderstanding. He offered to upgrade the software. I asked for ZCP coding and he said he couldn't do that.

I coded the rest with my Esys software and cable but not everything can be coded like my previous I-step. I guess I need to learn how to code the ZCP myself!

aboulfad What (and where) are these ASD gearsound parameters?

I got the MPE fitted, and the dealership also updated to 17-03-505. I now need to FDL code my previous settings and would like to play with some new stuff as well. Mine is a UK model 2017 standard M4 (non CP).
