Jaguar Remapping

Our Experience of Remapping Jaguars
At MSK Remapping we have the pleasure of working on a great number of different car makes and models, all with little differences when it comes to working on them. In this post we are going to specifically look at our experience with Jaguars. We have had the pleasure of working on a great number of Jaguars now, the Jaguar XE and the Jaguar XF being the most common we have been requested to work with. This in large part is because of the Adblue issues that plague modern cars, including Jaguars, now there can be multiple diffenert causes for these faults but they inevitably happen and normally the first signs is a Engine Management light followed by a countdown timer to engine no start, because of this we have been asked on multiple occasions to provide our Adblue solution for customers with this timer. Our solution is effective and difinative in that once the work is complete you will no longer have any adblue related faults on your vehicle moving forward.
Performance Upgrades
On the other side we have been asked to upgrade the performance of some of our clients Jaguars using our Engine software upgrade and in some cases our Gearbox software upgrade as well. This has raised the performance of these jaguars exceptionally well, on the lower end jaguars of 170BHP to 220BHP and at the top end with higher specification Jaguars with the V6 and V8, we have reached over 400BHP on our software. With our experience of Jaguars we have learnt that these cars can been unpredictable and therefore proper knowledge and care must be taken when doing any form of software on a Jaguar. one of the reasons is because the ignition on most Jaguars will turn off automatically after 10 minutes which if you are in the process of writing new software to the vehicle when this happens, it will corrupt the Engine Control Module or ECM which results in the car being unable to start and a large repair bill for either a new ECM or having the orginal fixed, however at MSK we use state of the art equipment which cant write the software in as little as 3 minutes, long before this issue could happen. Another common issue is that when the upgraded software is being written to the car, the large cooling fan comes on which draws a large amount of voltage from the battery and if the battery falls below 10V on average will automatically tun the ignition off which in turn will corrupt the ECM but at MSK we have a solution, by using the latest in battery support technology we keep the battery voltage at a constant 13V or higher so no matter what voltage draw is on the battery, it will never drop below the required amount for safe programming.
