I'd imagine so since the AT equipped 1.6L engines had cams with lower lift and duration than the engines paired with a MT.

I digress; it is my understanding that the Japanese cars had cams with a bit higher lift and duration compared to what our cars got. I have a custom ground set of cams in my car now. They're nothing too wild, and were made to be used with the factory valvetrain and engine management system solely for the purpose of reliability. I'd almost be willing to bet that I could use the B63H ECU with no issues whatsoever if I were so inclined.
