It is very hard to find a series 2 ECU, so I wonder if i can use a series I harness and run an external ignitor chip. Any input will be Great.

You have a few things mixed up here. The Series 2 RB25 has a ignitor chip built into the coilpacks not the ECU. People have used Series 1 ECUs on Series 2 motors without any problems. So you should be fine running a Series 1 harness and a Series 2 ECU.
