JAGUAR TUNING & PERFORMANCE SERVICES

Remapping is a software change in which we modify the operating parameters in the vehicle’s ECU (Engine Control Unit) program or ‘map’. We do not change or add any hardware in your vehicle. In many cases, the map stored on the ECU’s processor is accessed via on-board diagnostics port (OBD) in the vehicle. This diagnostics port is normally found under the dashboard. In some newer models, the ECU has to be removed from the vehicle and programmed on the bench. We believe that no matter the model, you will benefit from our Jaguar tuning services.

Once one of our professionally IMI qualified technicians read the ECU, they will upload the original map to the file writing team. During the mapping process, they adjust the parameters to maximise the performance, fuel economy, or a clever blend of both. Depending on the vehicle and ECU type, the remapping process normally takes less than an hour. This process sometimes takes longer, if it needs to be programmed on the bench.

SR Green

£249

Designed to return an improved economy in turbo diesel engines. At lower rpm’s you will benefit from additional performance and improved economy. We achieve this by re-characterising the torque limits on the engine.

Due to ECU security parameters, bench tuning is required when a vehicle is unable to have a map uploaded via OBDII. This process enables us to safely and securely remove the ECU from the vehicle. After which, we alter the map with the required SR tune.

SR Blue

£249

The most popular remap choice, offering the best mix of power and economy in virtually all turbo diesel engines. Designed to de-restrict the engine and open up the true torque and power range.

Due to ECU security parameters, bench tuning is required when a vehicle is unable to have a map uploaded via OBDII. This process enables us to safely and securely remove the ECU from the vehicle. After which, we alter the map with the required SR tune.

SR Red

£249

High Power & Ultimate Performance – Designed to fully unleash the maximum potential of your engine. Through enabling the power delivery to come late in the rev range, power is then in the optimum position for spirited driving on roads or track.

OBDII tuning is the fastest way to upgrade your vehicle characteristics. This is done through mapping with one of our SR performance maps. Depending upon the security perimeters on your ECU, we will need to remove it and modify it on the bench (please ask our team for more details, or contact us online).

Custom Package

£599

Custom Jaguar mapping adds much greater depth to the map. By extending the perimeters one step further, level of mapping is bespoke to your engine. Therefore this becomes ideal for modifications carried out to the full exhaust system and further forced induction options.

OUR EXPERIENCED & PROFESSIONAL SALES

OUR KEY PERFORMANCE SERVICES

Working with carefully selected partners, Swallows Racing has developed a wide range of performance and Jaguar tuning upgrades. Only using the best materials and technology tested in the most extreme environments. Track proven, race to road and now available for us to fit to your car.

Hand built, high flow stainless exhaust systems with 200 cell sports cats offer reduced back pressure and greater gas flow. This in turn offers increased horsepower and better sound. We also offer various stages of Jaguar tuning via ECU mapping. This comes with an improved throttle response, increased power, torque and economy, depending on your perfect package.

When you increase the cars engine performance, you should also consider improving braking and handling. Swallows Racing has the answer, offering packages that improve your Jaguar handling and braking. Be it either on the road or if you are planning the odd track day, trust in our Jaguar tuning services.

Swallows Racing also offers the conversion of your car to a stand-alone ECU. From adding greater utility to a classic, to creating a performance car that will be happy and responsive on track. From creating something unique and personal to having a more aggressive race look. With a range of carbon styling upgrades, badges and emblems, whatever your needs, we will help.

ECU remapping is when we take a read from the ECU’s processing chip of the manufacturers standard tuning map. We then adjust various parameters within the map such as fuel pressure. We also adjust boost pressure (on turbocharged applications), ignition advance and throttle pedal control. All these amongst others to unleash the true performance and economy. See our VRM (Vehicle Registration Mark) look up and discover how we will help your beloved vehicle.

Brakes are one of the most important supporting modifications when tuning your vehicle. You need to be sure that as well as accelerating faster, slowing down is just as effective. Simple physics; Upgrading your Jaguar brake pads and discs makes a huge difference to stopping power. But if you want maximum braking performance, one of our big brake kit is the way to go.

 

Improving your vehicles suspension increases holding on the road and the track. However, better handling is achieved with replacement springs, shock absorbers or adjustable coilovers. Tuning suspension helps reduce body-roll and increases speed stability when cornering. All this and more, giving you the confidence to push your car that little bit harder. Call us today on 01934 750319 or contact us online for a tailored made package.

 

A standalone ECU removes all the limitations of the stock ECU. Some stock ECU’s are either un-mappable or are not technically advanced enough to control the modifications installed. Upgrade your classic vehicle to fuel injection. Not only do the fuel injection systems provide increased power, they also offer hugely improved drivability, throttle response and reliability.

We offer a range of bespoke styling packages to suit you and your Jaguar. From genuine badges to full carbon styling upgrades and “R” packages. With our new range of carbon body kits, we have lots of options to bring your vehicle up to date. Switch up your style and add a suitably stylish body kit.
