MCLAREN UPGRADES

Litchfield OBD Custom Tuning

We offer a fully re-calibrated engine management system, providing significant increases to both power and torque. This customised ECU mapping releases considerably more power than standard or ‘off the shelf tunes’ and allows us to create a really smooth, driveable car. The process is straight forward and no longer requires the ECU to be removed and unlocked. We are now able to plug directly into the car and tune it straight away via the OBD port. This offers fast programming or reverting back to standard.

We have invested in our own McLaren 720S and have experience with everything from the MP4-12C, 650S and 600LT so we have been able to fine tune the calibration on our Maha Dyno but more importantly we are lived with Mclarens and have considerable experience with them on both the road and track. We feel we have developed the ultimate software upgrade for the Mclaren turbo engines. Particular attention has been made to the engines driveability and throttle mapping to ensure the new found power is as smooth and predictable as it is dramatic.

For customer looking to release the true potential of their Mclaren engine our remap service offers the ideal solution.

Our software upgrade for these otherwise standard McLaren models provide the following increases when using Shell Vpower:

SYVECS Replacement ECU

SYVECS is a British company specialising in complete replacement ECU solutions for some of the most potent performance cars where engine control and safety is of up most important. We are proud to have work with the company from the very beginning and have helped with the development of a number of products from the Nissan GT-R to Porsche 991 Turbo.

The Syvecs Mclaren M838T Kit kit brings a new level of engine management sophistication to the Mclaren 3.8l range which includes the MP4-12c, 540C, 570S, 650S and 675LT that use variants of the M838T engine.

Designed to work for a factory car or the highest level of motorsport the plug in kit offers the following to the platform:

Complete replacement of the standard engine management system that can be reinstalled at anytime.

• View any input live with built in scope up to 1000hz
• And much, much more!

Litchfield Limited Slip Differential

Our new Limited Slip Differential will transform how you Mclaren performs providing more traction, chassis balance and most importantly driver confidence to all current models.

Since the introduction of the MP4-12C all the way through to the latest 765LT Mclaren has installed the excellent dual clutch gearbox from Graziano. The gearbox uses an open differential which relies on the cars traction control systems to clamp the inside wheel to simulate the effects of a traditional Limited Slip Differential (LSD).

We found that this system whilst fine in theory has a number of drawbacks in practice and this can lead to the car having some unpredictably handling traits. On track it will also increase the wear rates for the rear back pads.

Our solution is the development of a new mechanical LSD which is similar in design to those fitted to Mclaren GT3 race cars. In our application the LSD ramp rates and pre-load are designed to work with the existing traction control systems and will often control the wheels speed indifference before the standard system has starting to apply the brakes.

The result is a much more predictable chassis where grip levels have increased under acceleration and when traction is lost the slide is more progressive and controllable.

Our LSD adds just 2.4kg to the low slung gearbox and the operation is quiet and smooth so there are no downsides to use.
