Ross, I have sold my XKR but I am still a member of the XKEC who have a good working relationship with
Paramount Performance
I asked about remapping the XF and this was the reply.
Thank you for your enquiry regarding upgrades for the Jaguar XF 2.7 D.
We can supply an ECU remap for the vehicle. Using our equipment and software we download the existing data from the ECU via the diagnostics port inside the cabin and examine the data for any spikes or flat spots in the maps. We then use the original data as a base to create our bespoke performance version, leaving manufacturer data and parameters in place and therefore making the upgrade more difficult to trace. Once the performance version has been created it is then uploaded to the ECU.
We cannot make any guarantees that the upgrade cannot be traced as the right person would know what to look for in a tuned vehicle. However, the majority of main dealers do not have that sort of technical expertise available so the chances of the upgrade being discovered are quite slim. In all the time we have been installing this upgrade we have had no reports of main dealers discovering them.
Once installed, the upgrade will provide an additional 35bhp and 60nm of torque. This will transform the way the vehicle drives with the extra figures available throughout the rev range. The upgrade can also provide a fuel saving of 2-4mpg depending on driving style. The additional power and torque allows the driver to move up through the gears quicker and also hold the gears for longer on the drags, stopping the need to downshift to maintain cruising speed. This results in more time being spent in the more fuel efficient lower rev range.
The cost of the upgrade is £699 plus VAT.
The process takes around an hour to complete and includes before and after rolling road runs to provide increase figures. You are welcome to view the process and wait in our customer area with TV and Wi-Fi.
