Who said anything about using a RS ECU for a WRX swap? You can't, the redline is the least of the issues, it has no concept of boost or fuel maps for a turbo.

Ahh, the boost and fuel issue was also brought up in one conversation. If the engine and ECU are from the same car, why is there such a problem with wiring? Is it from all the accessories (lights, dash, wipers, etc)?
