Digifant II ECU

Digifant is the name Volkswagen gave to its in-house derivative of the Bosch L-Jetronic computerized engine control system. The system tightly controls fuel delivery and spark to balance exhaust emissions and fuel economy with acceptably high performance.

Every A2 series 8-valve Golf, Jetta, Corrado and Cabriolet manufactured from late 1987 through the end of the model run in 1992 has it.
