I used to know the Pre96 ECU versions inside out. But my memory now fails me.
Thank God for Google and a post I made on Scoobynet 10 years ago.......
SA is STi 1, SB is STi 1 RA.
SA runs just over 1 bar
SB runs 0.95 bar, uses strange boost control and is very lean. I wouldn't run an SB in anything in the UK.
