Anyone else have issues with first gear loosing acceleration around 40 mph? I am forced to shift to 2nd. This is a totally different feel, than in my R56.
Don't know, if this is something everyone experiences, or just me. I don't drive like this all the time, but it's annoying, while having fun with other drivers.

 

I think the F56 has either a rev limiter or fuel cut by gear/speed. I was not paying attention once and just kep accelerating in first. Felt the engine cut out at some point near the top of the rpm range.

 

So, are you doing off road racing? If on the street, wow. In all the years I owned my R56 MCS, I was long out of 1st gear by 40 mph

But my fun with the car was typically more in the curves than 0 to 60 or quarter mile times.

 

Yes, I was thinking, there is a governor for that gear.
I put 3" pipes on the exhaust and gained some horsepower. Since there are more than one cat, it's pointless to change just one. So, I left them alone on this car. I also can't find where O2 sensors are either. I asked dealer and they don't have proper diagram.

 

Yes, on the street. Nothing could take my '08 R56. The '14 F56 is just as bad ***!

 

Sweet! So your R56 was untouchable?

 

40mph in 1st?
Did you take a look at the tach?
Your lucky the car has a governor.
Pull one ear lobe and let the Nitrogen out!

 

This post had O2 sensor info: https://www.northamericanmotoring.co...75-post46.html

 

That is correct!

 

I've noticed that the gearing is a bit different on this car than most others. In most cars, 1st gear is only useful/used from a complete stop and you must shift to 2nd gear almost immediately. On the other hand, 2nd gear has considerable torque, and you can accelerate from a near stand-still with it. Not so with this car. With the F56, you have to use 1st gear at very slow speeds (e.g. 5-10 mph). If you are coasting at those speeds, and shift to 2nd, you'll stall. I'd stalled a lot until I realized how different the gearing ratios on the F56 are that most other cars.

 

Do you have traction control off, your probably losing traction towards the end of 1st hear and the ecu his cutting power to the wheels. Take traction control off and try again. World of dofference

 

The F56 has so much bottom end torque that you can start off in third gear without stalling.
I certainly don't recommend this, but my lady has been guilty of this endeavor
on several occasions. She is a neophyte to the Manual tranny.
If you stall this little beast in second, you need an automatic!!

 

Hmmm. Not that I've experienced! I'm still assessing the situation, but I do know that I've stalled a lot more in this car already in one month, than I ever did in my last car during the whole of my ownership of it, which means almost never.

 

One thing to note is that the driving mode so dramatically changes the responsiveness that until you are used to it, you can easily stall out if your mind is not fully engaged. I don't have my F56 yet, but I always drove my R56 in sport mode just because the way it responded to letting the clutch out in first gear was so different that even after five years of driving the car I could possibly stall if I easily took off from a stop in non-sport but the mind was taking the clutch out and applying gas as if I was in sport mode. Sure it was easy to drive off in non sport mode, but you'd just have to go "oh, I need to apply more gas, and sooner".

 

Governor? You mean rev limiter right. We aren't driving steam engines. :-)

I'll throw my hat in the ring...

Rev limiter - protects the engine from damage when the driver hits the red line.
Car speed is not a factor.

Governer - also called a speed limiter. Prevents you from exceeding a set vehicle speed. Revs are not a factor.

The MINI has a rev limiter, but I don't believe it has a governer, other than an aerodynamic one.

 

Great suggestion. Will try it in the AM. Thx!

 

Thx

 

WHO is willing to take their Mini to 40 mph (or as close as you can get)
and report the rpm at that speed?
Go for it Doogood

 

What are the gear ratios? We can use math.

 

MINI does have a speed limiter. Whenever a vehicle specifications has a top speed, it is usually the spec of the electronic limiter. Sometimes this is explicitly stated: http://motoringfile.com/files/jcw_canada.pdf

In discussions about tuning, the topic of removing the top speed limiter often comes up: https://www.northamericanmotoring.co...r-removal.html

 

Assuming mini has not changed gear ratios from the previous Getrag 6-speed (1st gear ratio of 11.4:1), that would put the motor at about 6,000rpms at 40 mph.

 

My experience is with the Gen1 and Gen2s, not the F56. The OP was commenting that the F56 can't hit 40 in 1st.
Haven't you hit the rev limiter before?

The Gen2 S models should easily hit 40 MPH in first gear. Happens just after 6000 RPM in my R59. You can also hit 60 in 2nd.

I wouldn't try doing so on a hill though...

If the objective is to get to 60/62MPH or 100KPH, at what RPM should you make that shift from 1st to 2nd?

 

You should not be stalling. What mode are you in? Green? Mid? Sport? I have never had a problem with slower speeds in 2nd gear. I can easily accelerate from 5mph in 2nd. Even WOT. I do, though, always use the Sport mode. I hate Green mode starts (feels like I lost 2 cylinders, LOL) and Mid mode isn't much better.

As far as 40mph in 1st gear, I honestly don't see much benefit to that with the transmission (manual) and rear end gearing of these cars. At the 30-35mph mark my MINI S just feels like it wants the next gear. I find that there is lots of torque in 2nd so I normally shift at around 30mph on WOT runs.
