I just pulled fuse 14 and it works! The car feels stiffer and the steering seems more direct. Also NO codes light up in the dash. Thanks Mike, you just added dynamic mode to my '07. I booked a date with my audio/video expert to have a switch put it. Easy to do through a fuse. Thanks again...

 

Where exactly is that fuse again? Thanks for being the guinea pig! Very cool. Post up pics when you do the switch when you can.

 

In the fuse box to the left of your left foot on the driver's side. Will post pics when I have the switch installed for your viewing pleasure...

 

Hey, that's awesome! Looks like my thought process took the long way a round and you got the best solution djgold.

I saw someone mount a switch for something else in the middle of the cup holders where they form a V. Could be the ideal location for the "07-09 dynamic switch".

 

Damn! I am itching to do this now!!!!

 

Wow, I just did it. I wouldn't say it's like night and day, but it's definitely a "50%" improvement over the steering feel before. Much more precise steering at highway speeds. Also, there is much less shaking/loss of composure in the front end when cornering aggressively over uneven pavement. I had attributed this to the car's GT nature and that mine is a convertible, but it appears to be somewhat due to poor suspension tuning!

Is there any harm done by leaving fuse 14 unplugged permanently? Will my struts go out sooner?

Now all we need to do is figure out how to stop the transmission from changing gears when in manual mode.

 

Just drove to work without Fuse 14 this morning. I have to say, the ride quality is pretty darn bad without Fuse 14. Even smooth roads feel bumpy. I can see why Jaguar added the CATS system. However, for a spirited drive, I could definitely see wanting the whole system disabled.

I wonder where a good place to put the switch would be. I was thinking on the left of the dash near where the fog lamp switches are.

 

So I just had the ADCM disabled from my 07 XKR but the shop also left the shock connectors unplugged. I don't have a fault code on the dash, either. Can any one tell me if it matters whether the connectors get plugged back in up front? I don't like the idea of driving around with loose wires. Many thanks,

 

I don't know why people can't just leave it at unplugging a fuse. So many threads here, people unplug the fuse, then unplug every component in the system. Is there a reason for that?

(The power antenna thread is another example.)

 

As long as the ADCM behind the back seats is unplugged you can leave the shock tops plugged in (that's how mine is).

Another option is leaving everything plugged in and just removing fuse 14 from the driver's foot well fuse box. This method worked for djgold.

The only way you get a dash warning is if only the shock top connectors are unplugged and the ADCM remains connected.

 

I think the last piece of the puzzle to make it very close to dynamic mode in the 5.0L XKRs is a limited slip diff (where can you buy the Quaife one?). I just tried turning off traction control completely and accelerating briskly from a light, but the rear tires (actually, just one rear tire) lit up even without really giving it the beans (50% throttle max). Argh!!!

 

You can get one at Eurotoys. It's on my short list as well.

Limited Slip Differential for Jaguar XKR

 

As I posted before: I think you'll enjoy the price.

I got mine from a VW tuner... just google the part number QDF3W and you'll find the cheapest offering.

I paid $1100 in 2010 and $300 to install. Been loving it ever since. I've posted some b/4 and after donut vids in another thread and launch has significantly improved with the nannies off but you still need to maintain throttle control.

 

Thank you, Mike V.
Much appreciate your insight!
Regards,
Richard.

 

Dealer said car computers are so complicated he would not mess with removing fuses or unplugging systems. Anyone talk to a dealer and heard similar advise?

Is there a Jaguar tech support number for owners?

 

For those concerned with warranties or what the dealership reaction will be:
DO NOT MODIFY YOUR CARS IN ANY WAY WHATSOEVER!

For those not concerned with warranty or the dealership standards:
HAVE AT IT!

I'm tired of discussing mods and someone being "the voice of reason"

If your that concerned, just stay stock and let us others have our fun.

 

I had to plug the fuse back in today. The ride quality was too sucky for everyday use. Now the drive is pretty floaty and mushier, though.

How exactly would I go about wiring a toggle switch to mimic plugging in and removing that fuse? Can somebody show me the hardware I'd need online somewhere? It seems like a toggle switch would be easy to maneuver into the dash somewhere (there are some gaps between the steering column and dash) so that it could be undone when selling the vehicle, etc.

This is the closest I've found to what I think I'd need. Isn't there a way I don't need to pay $105 for it?!

 

Just go to radio shack and explain what you want to do. They could probably set you up with something under twenty bucks.
