VAG IMMO EMULATOR

Very old project, but sometimes useful  : immobilizer emulator for VAG cars.
Currently, VAG immo emulator is the fastest, easiest and cheapest solution in case defect the Immobilizer unit in old VAG cars
( 1995 to about 2000/2001 IMMO1 and IMMO2 ). Presented solution we use more than ten years; It has some drawbacks, but
is simple, tested and working. Project based on AT89C2051 microcontroller and can be modified in many ways.
Working module, in the basic version, you can build within several minutes.
