C. 1987 Single Board - Single ROM ECUs
Vehicles: Z31 300ZX VG30 1987, VL RB30
These ECUs only contain a single chip such as pictured below one 28 pin ROM chip
1. Remove the factory ROM chip, install a 28 pin machine drilled socket
2. Then test that the ECU still works by placing the factory ROM chip in the socket and checking
the vehicle runs and flashes LEDs when in diagnostic mode.
Installation of the Nistune board now follows the same procedure as for other 6802 based ECUs.
