We’ve had the pleasure of working on this increasingly customised V12 XJS on a number of occasions. On its latest visit to our workshop, we’ve been asked to install our Digital Engine Management (DEM) system. The system will release more power, and will allow us to optimise the fuelling and ignition for other modifications, such as cold air inlets.
Modifying these engines would normally have little or no effect, unless the fuelling and ignition is re-mappable. Without specialist knowledge of the original firmware-based map and ability to re-blow vintage eproms, this is not really possible.
Our modern Omex system, however, allows for full re-mapping. This XJS was dyno-tested at just over 300bhp, prior to any modifications being carried out. Once the installation of the system has been completed, we will be able to check on the gains we’ve made.
Another advantage of the modern engine management is the much-improved reliability. The old Lucas system using the AB14 ignition amplifier is prone to failure when hot, the new system ensures this is no longer an issue.
