Sport mode, not

Post by flybobbie » Mon Oct 22, 2018 8:13 pm

This stupid car.
Nearly got caught out by being in normal mode instead of sport.
Always set sport mode as soon as i start up. Stopped by a shop and forgot to set sport.
At my usual journeys dodgy turn, car goes flat as a fart trying to accelerate before a car appears over the blind hump.
It's just stupid having these different modes in 23i, it needs all it can deliver to get going.
Why can't it just remember the last mode selected.
Keep meaning to make a pulse circuit and relay just to set it automatically from start up, use power from cig lighter socket.

Just bought a Berlingo to make in to a mini camper.
Straight away a much nicer drive, doesn't follow every bump in the road, slick gearbox.
Thought the zed was going to be a refined car.

Is that the same as a pick & stick path which holds up via one of its own up contacts? :?

If there is any thing in there similar to an E85, then they learn your driving patterns any way. One reason I have never botherd to press mine in 7 years of owner ship. I prefer the car to drive the way it does every time. The throttle is plenty sharp enough since it knows I like to push it all the way down. :wink:

Clutching at straws if you rely on the difference between sport mode to normal in order to greatly enhance the driving characteristics of a 23i E89 :cry: it altered the steering feel on my 23i , can't recall it ever adding a turbo to it :P

Throttle response improves in sport mode. Even if you floor the accelerator it take fraction of a second more to pick up in normal mode. Just annoying. I can understand the need on a 35i in say snow. On 23i feels like you towing a caravan.
I have not noticed this car learn driver style like the MGTF i owned.
That would go into sportier mode with a few brisk accelerations or could be reset by pumping the throttle several times after start to reset the memory. Almost like an instant tune up. Nice system.

That’s the problem when you build a platform that has several engines and changes over time..

There will be combinations that either need these facilities, can benefit from different modes and there are those where it’s a waste

One big issue is that comfort mode gets the best co2 mpg hence for no other reason it will be present..

On the N20 with a remap the need for sport mode is reduced most of the time, enough pick up in comfort mode..

Another benefit of modern auto boxes is the knock it across to go into sport mode...

I drive 3 cars with the same logic and I habitually just knock the auto shift across to get sport mode as a precursor to overtaking on almost all non dual carriageways :thumbsup:

Does it actually make a real world difference in terms of timings for getting out of trouble? I can't see that a few milliseconds quicker response to kickdown is actually going to do anything in real-world conditions other than have a different bum-on-the-seat feel?

Oh yes it does,

The starting revs for each gear is up by 1000-2000 rpm and the upshift takes place at max revs rather than short shifting...

Especally with the N20 turbos it makes a big big difference ..

Carly can code the car to remember the last state of the stop/start function, I don’t think it can do the same with sport mode. :thumbsup:

I can understand it going back to normal for the 35i, but for the 23i it's a gimmick.
If you drive all the time in sport as i do, the old leg muscle memory is for the sportier response, only to get caught out in normal mode. So requires a push, realise your not in sport, then full throttle.
It's just annoying and unnecessary.

My daily turn. I need to turn right. Car emerge the other way doing 50-60 plus. Worst are low cars.

A remap would be able to change the throttle map to be the same in normal and sport mode. I have done it on my 35i as it makes no sense to have the throttle pedal change between modes.

It won't make the auto box behave differently though, so unless your car is a manual the problem of a dimwitted gearbox will still be there.
