So I have a 78 280z with an L28ET swap. The motor/distributor are from an 83 Zx turbo and the current ECU/harness is from an 81 280Zx turbo. I would like to try an ECU from an 83 so it matches the motor/dizzy. The current CAS is in the dizzy on my car and the injectors use the dropping resistors that came stock from 78. The 81 ECU requires the external dropping resistors and the 83 ECU I want to use does not require them. I believe the resistors are located inside the 83 ECU. What is needed to make the 83 computer work on my setup? Is there something I need to do to the resistor wiring? Thanks. Hope I was clear.
