Details of our 251 bhp re-map for the 2.7D XF (and all other Jag 2.7Ds).

Please get in touch by private message, e-mail at [email protected] or phone us on 0800 7565347 if interested. Please post questions on this thread if you have any.



V6D Performance Engine Map

Our engine re-map for the XF V6D has been developed in conjunction with leading performance specialists DMS. This map boosts the engine’s power to 251 bhp and our XF has shown an increase in fuel efficiency of up to 3mpg depending on driving conditions.

These headline figures are also combined with a significant improvement in mid range torque and driveability, with improvements to the standard XF’s sluggish low rev performance and part throttle response. This banishes the standard XF’s tendency to pause when moving off the line or from a slow speed rolling start.

The map is flashed straight into the vehicle’s engine ECU by our engineers and is performed at a location of the owner’s choice. It is a full re-map so changes turbo timing and sequencing and fueling where necessary and retains the cars adaption system. This ensures performance, driveability and reliability and is not the same as a plug in chip that merely changes fuel pressure.

The car will be re-flashed for free if the software is subsequently overwritten by a Jaguar dealer update.

Specifications:

• Power: 251 bhp @ 4000 rpm
• Torque: 385 lb/ft @ 1900 rpm
• Fuel Consumption: Up to 3 mpg improvement

Performance Figures:

0-60 mph 7.2 secs (standard Jaguar claim 7.7 secs)
0-100 kph 7.4 secs (standard Jaguar claim 8.2 secs)
50-70 mph 3.8 secs (standard Jaguar claim 4.4 secs)
1/4 mile 15.2 secs (standard Jaguar claim 16.0 secs)

The pricing structure we are going to put in place is a 10% discount to forum members for us to travel to you to apply the map anywhere in the UK and a 25% discount if you travel to DMS in Southampton to have the map applied there. Normal terms and conditions apply in all cases including reflash guarantee.

251 bhp Re-Map:
10% discount: £765 + VAT = £879.75
25% discount: £637.50 + VAT = £733.12


To qualify for the discount you must have made at least one post on the forum. We are looking at doing a further discount for a group buy of 3 or more people.

Went down as a modification, they didn't ask much other than did if affect the value of my car.
I just told them that i need to add a modification to my policy. It was classed under engine modification.

Didn't up my premium.
don't forget each insurance company has a different definition of 'modifications'. Most have limited knowledge of them

I'm sure people will have very varied responses from their insurance companies

There is a phrase which an insurance company uses "Full disclosure" and I suspect that they would say that you have not fully disclosed the nature of the modification. I think it may be illegal not to tell your insurer that you plan to modify the performance of the car and often the insurer will be happy to ignore it, if the power increase is less than, I think, 40bhp or thereabouts.
If I were you, I would get them to email you confirming that they are content with your description of the modification.

I currently work as a business consultant for an insurance company and have worked on similar things for other insurance companies

any materials changes to an insurance policy will result in a new policy schedule being released.

Many motor insurance companies only have a small high-level list of 'mods' and generally don't care about these thing its only anything that changes the characteristics of the car or the value requires further detail or independent inspection.

Some companies will interogate you and others won't. Its pot luck on your insurer.

Well you may be right. :)
However I do know that every comparator site I visited today in order to obtain a renewal quote asked the specific question "had the car been modified". So in order to discover what then would happen I ticked to say that I had modified my car. I was then presented with a list of modifications, one of which was " chipped engine management". This seemed to be the most appropriate.
After the market scanning process had been completed I noticed that most insurers had fallen away and I was left with the choice of about 3 companies.
More interesting was the fact that the minimum loading for the modification amounted to an extra £160 or so. :!:

It will be seen, in the screen shot below, that the declination by other providers is stated to be because of the modification.

Good research, pekem, and not in the least reassuring! I suspect that some of our colleagues may be relying too much on the mods not being discovered. The principle, in this context, of FULL disclosure is surely unarguable, and the moral justification for this approach rather escapes me.

it all depends on the insurer i think :)

i wouldn't make a judgement on the basis of internet quotes - they're computer generated on the basis of what details you enter into the system. if you go to the website of an individual company rather than a configurator site they'll often make the assumption that the car is unmodified.

i've never had a problem with adding modifications to a policy. but i've also made sure that before buying the mod i phoned to check the insurers would accept it. sometimes it's been free to change the policy, sometimes there's been an admin fee. it's never caused a massive hike in premium

my advice would be if you're going to change any aspect of the car, ask your insurance company if it'll pose a problem first. mostly it won't i think. however, if you don't tell them, have a bump and they later find out you've modded the car, there's a real risk they'll void the policy :(

....and that's not necessarily just about a bit of minor bodywork, is it - what if there were serious injury involved?

all good comments above.
Please be aware and the Spires-st guys can confirm this but Chipped Engine Management is not the same as a Remap as one involves a direct change to the hardware of the car and the other is just a software change.

I can't decide if the point you make is disingenuous or not. As I understand it, and maybe I am completely wrong, re-mapping and chipping amount to the same thing in terms of end objective.
Is it not the case that because of the technical advances in engine management systems, it now only requires a software download, via a simple communications port(Re- Mapping), as opposed to the replacement of components ( Chipping ) :?:
Whichever method is employed, the objective is to increase the performance output of the engine and it is this aspect that the insurance company will want disclosing for underwriting purposes, not the method of installation.
Are you suggesting that if the specific question, "Has your car been re-mapped" is not posed but the alternative question "Has your car been chipped" is, then you would rely on the advice given to you by Spires-ST that the process does not involve "chipping" and therefore you could safely move on to the next question without further ado, surely not :?:

yes, the end result may be the same but the means of getting there is totally different which from my experience with consulting for insurance companies is where the difference in risk (and ultimately premium) comes from.

many of todays high performance cars can still be chipped as opposed to just having a software remap, it depends what you want out of it.
Again my understanding isn't great but don't chipped engine management units offer far more power/performance upgrades than can be acheived with a software remap?

With a modern car the end gains are the same between chipping and re-mapping, with modern ECUs the engine parameters are held within the software map where as they used to be hardwired into the chip.

Did some performance testing on our car over the weekend using a Racelogic Performance Box, so very accurate results. These were:

0-60 mph 7.2 secs (standard Jaguar claim 7.7 secs)
0-100 kph 7.4 secs (standard Jaguar claim 8.2 secs)
50-70 mph 3.8 secs (standard Jaguar claim 4.4 secs)
1/4 mile 15.2 secs (standard Jaguar claim 16.0 secs)

Very happy with the results, they compare favourably with the 3.0D (non S variant).

Very interesting numbers. :)
I am always left wondering when such results are published if a common technique is applied. For instance,which gear is used at the start, is it a rolling road, what is the weight of the cars etc. How can you be sure you are comparing like with like :?:

Well all we can do is test the car we have at its weight whatever that might be. Jaguar must do the same, their tests have to based on a real event for published figures.

To be honest technique is everything and I've not done this sort of stuff before so might be able to get some quicker times. Car must be at rest but then you have to build revs whilst holding it on the brake, and seeing as this is a transmission we've paid for rather than some prototype built to do 0-60 times it wasn't something I wanted to do a lot of.

Well my next door neighbour is a systems engineer with an F1 racing team and he tells me that weight, construction and fuel load, is crucial and doubts that a "real event" will be quite as you might imagine it :!:
