It's the only way I know that you could do multiple times without reflashing the ECU all the time.

The ECM in a ZR-1 cannot be "flashed" as the PROM is not a "flash-PROM or EEPROM. It's just a "standard" EPROM and for that you have to have special equipment to "burn" the chip.
You need a "PROM switcher". I don't even know if you can still get them, but they were common back in the late 80s and the 90s.
