Engineers are the worst car techs lol. I'd say he explained why it isn't on the 2015 cars and that's the deal.

Yeah, and the Mini pedals are just right for that. I could even do it on my R56.

 

Please delineate the difference between the 48 and 46..
Rated MPG?

The 2015 MINI Cooper S 2 and 4-door Hardtops feature a new 4-cylinder engine, designation B46.

It is the SULEV (super ultra-low emissions vehicle) version of the B48 4-cylinder 2.0-liter engine from the 2014 MINI Cooper S Hardtop.

The B46 is rated at 189hp and 207 lb-ft. torque, the same as the B48
The difference is emissions rating.

 

Probably not. A 5th to 2nd mis-shift will cause a mechanical overrev; physically forcing the engine to rev higher than the software determined limits.

I would speculate that it has to do with all of the new emissions requirements.

 

Yeah as a vaguely recall it didn't require any repairs, but he was worried that he'd damaged something and it would show up later and that the car would "remember" the error and void his warranty.

 

Gonna come unglued if this is true of the 2015's. I had a 370z and its best feature was the rev matching. Bought a new mini because of this vs a leftover/used. Second gear is what is used most often going into turns (for me anyway) whether it is street or track.

 

If I could I would, but the only published difference is the SULEV. But it's still a different motor and if the 2015 is not rev-matching as the 2014 it's either a software difference or an engine difference. Transmission is the same.

 

It seems the electronics would not let the engine over rev.

 

I'll go ahead and confirm that my 2014 MCS does rev match going down to 2nd gear, always has unless I turn traction control all the way off by holding the bottom down for a few seconds

Definitely love the feature as it really helps with smoothness while doing normal driving. Not sure about during hard shifts sometimes I think it has trouble keeping up with quick downshifts but if you just let it take its time it really helps with cornering stability

 

CooperB:
"the only published difference is the SULEV. But it's still a different motor."

SULEV is just lower emissions rating.(Re-Map?)
Saying it is a different "motor" would be the same as saying if I changed the air cleaner to a K+N air cleaner that would make it a different engine.
The rev question remains.

 

My 2015 Cooper does match into 2nd.

 

And the plot thickens...very strange.

 

My 2015 does not rev match in 1st or 2nd

 

My 2014 S does rev-match.

BTW, you can get it to rev-match into first (2014 at least), by going 3-2-1 without lifting the clutch. Maybe same thing works for 4-3-2? Either way, it's kinda lame... if it's possible to do it, why does it only work with that pattern and not direct from 2nd? I think Mrdi is right- must be something with emissions, or maybe MPG. I'm sure shifting technique is specified in the EPA MPG tests. Even though it's rough on the clutch (and everything else), downshifting without rev-matching would use less fuel.

 

My 2015 BASE MODEL does rev match every gear except first.

It's weird for me to not heel-toe but I used this feature extensively last night on a twisty mountain road just to see how well it works. The third to second downshift was the most used and it worked flawlessly.

My wife has far less track time than I do and she loves it. It seems to work great... Now I REALLY wonder why the S version doesn't have it when our base model does...

 

Yep, my 2015 mcs does not either. Happened to notice that a few times while out driving today. When everything else is so smooth, it is unnerving when you go to second and it's not. Still getting used to my mini as this is my first one. Thought I was doing something wrong......Gus's not!

 

My 2014 MCS manual has the Rev Match

 

After this discussion, I am very happy that I ordered the sport-auto.

 

I put the question to my dealer. He is a track guy so I am sure he will be taking this seriously since he has his eyes set on a 15 for himself. I will see what he comes back with. Maybe (fingers crossed) it is a setting change. Online owners manual does not have anything on rev matching.....strange.

 

People with 2015 models- let us know if yours was before or after the hostage crisis. I wonder if the ones received before got through with the old rev-match computer. And part of the delay was removing this function to raise MPG. At least based on how the EPA tests.

 

As I wait on mine, I had my dealer try two cars he had on hand and neither did the matching in first or second gear.
I sent an email to several VPs at Mini. One replied saying they will look into it. I asked them if they could reflash somehow.....no direct answer to that.

Holding my breath

 

In the US all 2015's were held were held. None got through before.

Edit: I believe it was all 2015's in North America

 

I think you're right, and Canadian cars were held hostage too. Weird that some match and some don't, in 2nd gear. I'm guessing you either have it or you don't and no software update is gonna change it.

 

The service manager called me Saturday to discuss this (among other things) and is supposedly looking into why the change and if it's reversible. I think it's a software feature so it's not likely to be reversible just because the dealer wants it to be. He suggested it may be possible to roll back the software to something which has rev matching in second but as a software engineer, I don't want that. We don't just stick features in a release but tons of bug fixes as well and a buggy car is an unhappy car (and owner).

I'm not sure that anything useful will come out of his investigation but I'm happy he's at least trying.

 

It sounds like all of the S models had it removed. The base Cooper hard tops still have it.

 

Gee, I shall have to try a 90 mph 6th --> 2nd shift with rev-matching enabled. That should be exciting!

With only three cylinders, surely the rebuild will be inexpensive...

Cheers,
