The engine came with Volkswagen’s own Bosch ECU but this was rights protected and inaccessible. Instead, Pectel hardware was used, giving a blank canvas of zeros for Caterpillar to code its engine management strategies.

Taurus removed a 5.0-litre TDI PD V10 from a Volkswagen Touareg, liased with another British firm, Mountune as its engine partner and married it to a Lola B2K/10 chassis. Mountune had already carried out design studies on racing diesels.
The Touareg’s Bosch ECU is rights protected and so Pectel hardware was used enabling Caterpillar to code the engine management strategies.
With conventional wastegated turbochargers or fixed geometry turbochargers (FGT), a turbine flow area cannot be adjusted during operation.
Knocking is abnormal combustion in which the air-fuel mixture ignites prematurely due to exposure to high temperature and pressure, creating an unwanted high-frequency noise. When the compression ratio is increased, the temperature at compression top dead center (TDC) also rises, increasing the probability of knocking.
