I have been playing more and more with the sport mode on the xjr and I am convinced that the gearbox shift patterns can't only be the single thing that changes.
I work for vw and Audi and have worked on loads of autos there sport mode is really tame compared to the xjr.
As u guys well know in normal drive the xjr is such a cruiser,really tame,still gets up to motorway with ease,but in sport mode it's like someone has stuck a rocket up the
exhaust.
Surely the engine map must change when in
sport,along with the gearbox map,it's to
different a car for it only to be the gearbox
that changes.
2maps on the engine ecu when the gearbox changes into sport?
Would love to see a torque graph from 0-60 for the different modes,because they must radically different.

Opinions?

One of the biggest things it does is engage 1st gear. If you have CATS, it firms the dampers. I wouldn't be surprised if it made throttle response quicker since it's a drive by wire system. Engaging sport mode and turning traction control off is tire shredding fun.

I will be getting mine dyno'd soon via the HUB so I will get them to do 2 graphs ;-) .... Bet the torque curve goes nuts in sport mode lol

Sorry to sound dim but what is "CATS" and how do I know If I've got it?!:confused:

Computer Active Technology Suspension, Jaguar's adaptive suspension. You can tell by looking under the hood (bonnet) at the shock towers, if you see wires, you may have to remove the black plastic covers, you have CATS. You could also look behind the front wheels to spot the green shocks. I believe non CATS are black.

non cats equipped can have green shocks too, just no electrical connection to the top, also cats comfort shocks are black, just to confuse the issue!

Sports mode can be one of the best and worst things, when driving it normally its horrible, holding gears far to long etc etc. When you want to drive hard it really brings the car alive, you get first gear off the line and it sharpens the gearbox up no end.
These are the only differences though, there is no power difference or suspension difference when sports mode is enabled.

Thanks... looks I have the 'CATS' fitted then!
But why does it feel sooooo sloppy?! It really does feel like you on a ship, it can be quite annoying!
Perhaps I have worn bushes or something?

Hmmm, sounds like theres sumthing wrong somewhere mines nice and comfy on the motorway, but can be a bit annoyingly hard round pot holes and bumps, certainly not shipblike.
