Software Development

We have an extensive research and development department that is constantly pushing the boundaries of engine management software in order to give you the best possible performance.

We perform real world tests which produce the stats that back up our claim to being the most advanced performance software available in the world today.

All Custom-Code remaps are developed using real-time rolling road sessions as well as live road testing feedback to make sure the remap is optimised for real world driving. We have thousands of hours invested in the research and development of our software. We are constantly fine tuning our maps in order to gain every last bit of safe performance from a particular engine. We test our own engines to the limit to ensure that your engine is remapped safely and receives the best possible generic or custom remap available.


We have a custom designed rolling road which is recognised as the most accurate in the industry. It is a true load-based dyno, so you can be assured that the results you see after having your vehicle remapped are the results you will see on the road.

Custom-Code pride themselves on their constant development and innovation in the software industry, adding new functions and features to both current ECU types as well as the latest generation. VVT Attack is just one of the latest innovations of Custom-Code software available for VVT equipped cars. Custom-Code two step launch control is also now available for most ECU varieties across the board, bringing race technology to your vehicle.
