Additional functions

    MPI/MPFI represents very expensive system of the injection which control unit in addition operates electronic ignition. The control unit system of injection of MPI/MPFI is capable to complete diagnostics. It means that the failures arising in use, remain in a computer memory information in which is erased only after accumulator shutdown. In this system that also those defects which arise only for short time are remembered is ingenious. By experience, it just those defects which it is most difficult to find. After 50 starts of the engine the defect which has appeared only once, is automatically erased in memory of the computer.
