I don't have to have dyno charts, I was merely saying that the car will run with either ECU. I'm not claiming one makes the car run better than the other. Other than video taping me swap ECUs, and going for a drive, I can't feel anything operating abnormal in the engine compartment.
Now, I have here sitting on my desk both ECUs

The 5 speed ECU part number is 89661-17130 with red 4AGZE letters

The Automatic ECU part number 89661-17120 with green 4AGZE letters

My engine is completely stock, but it was blueprinted, balanced, with most components brand new. I run premium gas all the time, but it's just out of habit.

Not confirmed, but I heard once that the only differences between SC ECUs, was that the automatic ECU does not have a rev limiter.
