Rev-match enabled in Sport+ beginning July 2018 production? UPDATE: Confirmed

It would probably be cheaper to get a generic module that puts out a command on a CAN bus. They have cheap DIY modules you can buy and program online for next to nothing. The issue is getting the DME to respond to said command, and execute the change. I'm working on that now.

Anyone else had any instances where their rev match did not engage in any mode at all? As much as I'd like to think that I accidentally came across a secret way of turning it off completely, gut feeling tells me otherwise. I turned the car off and back on and rev match is working fine.

This has happened to me a few times (along with the opposite scenario, where rev-matching is on regardless of drive mode). When you cycle the key, it all defaults back. It's caused by a software error.

Hey all, quick update:
Good news/Bad news. I got this working, but burned my DME up in the process. It worked for a few key cycles, then died in my bay. Currently, I have faults for no communication to the DME, and a metric shit-ton of CANBUS faults. The new DME will be here Thursday. I'll recode it and try again and we'll go from there. Happy new year!

Thanks for all your effort here.

Forgive my lack of technical understanding, but what specifically are you trying to accomplish? Simply coding in/out rev match? It was my understanding that BM3 or other aftermarket tuners have already done this.

Or are you trying to find the code that allows newer production F8x's to rev match in sport + and see how it differs from the older production models that doesn't act this way?

For me personally, I'd love to be able to get a BMW software update that makes my 4/2018 production rev match in sport + just like the newer models do.

Either way, really appreciate your efforts and for keeping us all updated!

I'm attempting to make rev-matching both toggle-able, as well as being able to use it in Sport+.
I've coppied the firmware from one of our (dealership's) last-run F80's and have noticed no difference. It won't rev-match in Sport+. That same last-run F80 won't rev-match in Sport+ with it's native software anyway, so I'm not too sure where that information is coming from. I've submitted a PUMA case with my own vehicle to ask the guys at HQ why these things won't rev-match, and they basically said in a nutshell that it's not supposed to at all, regardless of production date. Granted, this could be wrong, and that would not be the first time I've seen this happen. I've never seen an F8X rev-match in Sport+, and I've driven all of em from beginning of production, right up to PDI'ing the last of the '18s.

EDIT: I'm in no way an expert on this crap, and am not claiming to be. I just like fucking with this stuff, so if anyone has insight, I'm all ears.

Gotcha. So there are multiple reports from people in this thread with production dates of June/July 2018 and on that confirm rev match is enabled in sport +. I also haven't seen it first hand. But more than a couple here have confirmed.

In your post on 12/3, I thought you confirmed that you actually drove a recent production F8x and confirmed that is did rev match in sport + ?

It did it for a bit, but then stopped. My '17 has also done that though.

The new F82 production cars has the same DME revision as the M2C due to the OPF support that's been added.

In these roms it seems like the CAL was modified to enable rev matching in s+. For those that have the FR's / A2L's which sound like you do. look for MDNREG
KL_ENA_NREG_DSC
KF_GANGSOLLFREIG_SPORT


I personally don't think coding the 2 part clutch sensor out is wise as you lose some clutch drag/clutch slip torque reduction safeties that the DME has

Just got my car updated at the dealer due to Carplay issues. DCT rev matches in sport plus. I honestly don’t remember if it ever did it before the update since I use Sport mode almost exclusively.

The DCT rev matches in every mode...

This was about 6mt

Gotcha thanks

My 2016 M4 6MT (15k miles) all of a sudden rev matches in Sport plus. : When I test drove it (CPO) last month before purchasing, I confirmed that rev match was only in Efficient and Sport modes.

I tried Downeaster1 's trick of cycling the key (which I assume means turning the car off then on again) but it still does it. Frustrating as I do like having the option of rev matching myself.

Before I take it to the dealer, I'd like to locate some official literature that states for at least the pre 2018 models that sport plus does not have rev matching, lest the dealer claim otherwise. I've read my manual and done some searches on BMW sites with no luck. I have found plenty of posts on Bimmerpost that verify sport plus does not have rev matching but my experience is that dealers tend to discount forum posts and only rely on official manufacturer guidance.

Not saying my dealer won't acknowledge it, but I'd like to be prepared in case they don't. Any help or guidance appreciated !

No, it doesn't. The DCT mostly does not rev match in S1 and D1.

BM3 doesn't help that much with this new rev match behavior. I have a 19 M2C and it rev matches in every mode unless you turn DSC fully off. For example, Sport+ with dsc on and Sport+ with MDM both have rev match while Sport+ with dsc off doesn't. In BM3, I enabled rev match in Sport+ thinking it would enable the rev match in Sport+ regardless of the DSC mode but nothing has changed. I prefer rev match off most of the time but sometimes at the track, if I'm after serious laptime I want to use DSC off with auto rev match. This really bothers me and even BM3 can't help as of today. I really wish there was a way to change this behavior.

[Humdizzle]

My 2015 will rev match in every mode except S+, regardless if dsc on or off.

not sure why you would really want rev match in S+ anyway. S and S+ are so similar as it is. they both keep the waste gate close under partial load to spool up the turbos quicker right? sport + is just a more sensitive throttle.

We’re going a bit off topic here, but no, that’s not what Sport+ is about.

Sport+ is actually the most direct connection between throttle pedal and engine response. In efficient, the response is dampened through different means such as a delay between pedal movement and throttle opening and wastegate activation. Sport is somewhere in between fully dampened Efficient and fully direct Sport+. Sport+ also dials up the engine cooling system.

Actually... sport+ like in all the other BMW throttle mappings is not a linear curve. You reach 100% load request by 85% throttle input, 90% in some cars.

The curve is not anywhere near linear at all.

As far as delay, yes there's some smoothing involved, but not really a time delay of sorts.

And lol. I really should remember some of my old posts...

F87 also gets the new rev match behavior, and yes already had it tuned out as soon as I got ECUTek.

I just wanted to post an update on this... BM3 recently released an update and now it's possible to enable/disable rev match in every drive mode even when DSC is off. It was not possible to enable revmatch when DSC was off but with this new update, I can now turn DSC fully off and have auto rev match in any mode I want (efficient/sport/sport+).

is this for 6speed? So the dealer just downloads new software and that'll do it? guessing I'll have to re-do my coding then..

[MyFragileHalogen]

LOL perhaps BMW is slowly trying to get people into AT by baiting and taming people with auto-rev match so that it makes them easier to discontinue 6MT cars production.
