Link Engine Management has been going strong for 20 years, but has skyrocketed in the last five to become a worldwide name in engine control unit engineering.
Engine control units are a type of computer installed into vehicles to, as the name suggests, control the engine.
This could be to make certain injectors fire at certain times, or make cylinders inject fuel sequentially.
Cars come off the factory floor with a default setting, which could be for a car sent to Mexico city, or to Christchurch.
Link takes those control units and replaces them with a custom one.
The customisations could be for performance, fuel economy, or to get the car to run stronger at higher altitudes – if the car was used for a hill race.
There are around 20,000 variables for an engine control unit – a lot of information to work with.
A car with 350 horsepower can be turned into one with 1000 horsepower – an every day rider into a racer using engine control units.
