Hi all,
So I thought I read something in my manual about how my 2014 XKR convertible will remember and conform to how I drive. Anyone familiar? Just curious as I tend to drive extra cautious and courteous around town, but don't always get that burst how I'd expect when I need it.
I recently replaced the water pump for free under warranty before it became an issue (lucky find during oil change) so I know that isn't it. If I drive a bit more aggressive, it's usually there when I need it. But can you put this beast to sleep driving around like a grandma for a while?
I'm talking when the car is already warmed up too.

Thank you,
GR

 

I've heard that, as the car expects your little aggressive romp to be short, and not worth going into Beast Mode.
When I had my injectors replaced, the shop had the battery disconnected for a good while. When I got it back, it had to relearn my sadistic and annoying habit of WOT and Idle.

 

Yep was the same in my X100, in that if you wanted to get it to relearn, this was don't by disconnecting the battery for 10 mins and then touching the positive and negative battery leads.

Not sure on the procedure on the far more sophisticated (?) X150

 

Yes, the adaptive learning curve messes with the throttle response and transmission timing. I find it ironic that the car performs more aggressively after a hard reboot. Tells me I'm not pushing it hard enough...

 

they have and other cars have been doing this for years. Adaptive ecu's for engine and transmission. I used to have a Orthopedic Surgeon for a customer with a XKR. He like ceejay was full throttle or idle and usually got 3 sets of rear tires for ever 1 front set. So hard I was surprised that even the abs traction control gave very little to no intervention and allowed you to annihilate rear tires.

 

My car and I have an understanding. I don't mind if it remembers how I drive, as long as it doesn't tell anyone.

 

Same here.

I would rather have the car snappy in automatic.

If I want it slow I can manually shift that way.

In an emergency I want to put my foot down and have go.

Going slow is not an emergency.

A pity we can't select our own maps.

 

Typically how long does it take for the system to adapt to a "new" driving style?
A few miles or a few hundred?

 

Many others here have this same recollection (myself included) but I cannot find it in either the US or UK Owner's Handbooks. Also checked the XK/XKR sales brochure but it's not there either. I don't plan of reading the entire Workshop Manual but a search for "adaptive learning" brings up zero too.

Now I'm more worried about the information source than the vehicle performance!

Page 1765-1766 of WS Manual

 ASIS (adaptive shift strategy), to provide continuous adaptation of shift changes to suit the driving style of the
driver, which can vary from sporting to economical.
 Connected to the ECM (engine control module) via the high speed CAN (controller area network) bus for
communications
 Default mode if major faults occur
 Diagnostics available from the TCM via the high speed CAN bus.

 

You can, go to Viezu and give them $775.00 for the XKR-S tune

 

Dynamic mode (in the 5.0s) helps. I rarely drive with it off.

 

OK - I AM impressed.

A mere THANKS wasn't really adequate in this instance.

Ride and Handling Optimization
INTRODUCTION
JaguarDrive control is a selectable vehicle optimization system designed to fine-tune the driving characteristics of the vehicle by accommodating different driving conditions or driving styles. The system allows the performance envelope of the vehicle to be stretched and prevents the necessity for a single, compromised configuration for all conditions. JaguarDrive control increases the vehicle's abilities by changing the characteristics of engine mapping, transmission shifts, stability and traction interventions, suspension settings and, on SC (supercharger) vehicles, the electronic differential settings.

Engine Management Adaptions
After a battery disconnection/re-connection, the engine management system loses various adaptive settings (fuelling, etc.) resulting in a slight deterioration in engine/transmission performance such as idle quality and automatic gearshifts. No action is required, as the system will automatically recalibrate during a normal drive cycle. The vehicle will require to be driven for 16 km (10 miles) or more to re-adapt.

 

I've been trying to work out just how insulting this is.

Graham

 

So it's not clear to me, is this constantly adapting every few miles? Because if I drive crazy for a while the car certainly starts to respond accordingly (keeps revs high, won't downshift right away), but if I calm it down the auto eventually chills out after a couple of minutes.

People talk like whatever this mapping is is set for life and you have to hard-reset if you want to restart the process, but maybe it's just constantly changing, so it's not really that "smart?" If this were so it would have no real memory of how you drove 20 minutes ago,

5.0 NA

 

It has to be dynamic, because you would not want the car to be 'locked' into one driving style. It needs to react to how you want to drive, but not instantly. For example, if I do a lap of the Nürburgring, then come in to the carpark to buy more credits, I need it to stay in a track mode so that it will behave like a race car when I go back out. Conversely, if I'm pootling to the supermarket, but do a quick blast off the lights to annoy an Audi driver, I don't want it to jump into track mode. Basically, there's an averaging process built into the driving-style assessment, which gives it some hysteresis so that it isn't constantly swinging between extremes.

 

Would this adaptivity (is that a word) of the driving, shifting styles, improve the 1200 rpms rumble/why hasn't this thing down shifted? problem? I know there are expensive parts you can put on the exhaust to stop it, but I was thinking if it learned how you drove, and you frequently drove at lower speeds in stop and go traffic, it would LEARN to downshift? I certainly did when I learned how to drive a stick.

 

No, because it isn't targeted with addressing that issue. What it tries to do, I believe, is make the car sharper & more responsive when you're pushing it, and softer & more relaxed when you're just tootling around. But it does that within pre-defined limits, so it won't get more and more soft the longer it is driven gently - it progressively moves to one end of its performance envelope, and that's all. Likewise, it won't eventually turn into a rock-hard twitchy race car if you keep driving like Lewis Hamilton, it just goes to the other end of the envelope.
