-====== Overview ======
-With a 2G ECU, when removing the EPROM it's entirely possible to damage a track on the top of the board and still allow the engine to run, but cause a number of malfunctions.
-If the engine runs, it indicates that the connections between the processor (IC1) and the ERPOM are okay.
-====== Details ======
-Check for continuity of the tracks to the EPROM as follows (note that there is a 100 ohm series resistor between EPROM pin 22 and IC2 pin 44):

-Pin numbers for IC1 and IC2 are printed on the PC board. The EPROM pins are numbered as follows:
