English to Polish Tech/Engineering Computers (general)

To make dynamic calibration changes while the engine is running, PROM-based systems typically require a device called an emulator.An emulator plugs into the PROM socket of the OEM injection microcomputer in place of the stock PROM and contains a socket to accept the stock PROM, which is loaded into emulator RAM for testing and modification, and eventually offloaded into a PROM-burner to create a new replacement PROM that can be installed when the emulator connector is removed from the socket.
