"Batch" means more than one injector is triggered together. "Multi-port," at least in GM, means on injector is placed at or near each intake port. The 7749 operates on "batch-fired Multi-port injected" engines.
This is a very steep list. The 8051 you referenced previously does not meet all of these specifications. Actually, I am interested ecm's that do meet this spec. How would the ecm get feedback to determine an individual cylinder fuel calculation needs adjustment?
The 7727/730 is a very capable ecm for the engines most people build. It does not match the specifications you have posted. It will read a pressure signal that ranges from 0-5V and the voltage can be interpreted as 2 BAR. Maximum rate of spark increase is limited in code and for most engines, the spark resolution in the tables is greater than what can be accurately delivered at the cylinder (reference this
graph of crank speed variation on a four cylinder engine.)
Engine control will be achieved through proper selection of a combination of hardware and software. You can use a 1227749 or a 1227730 ecm with a four cylinder "chip" or memcal along with a program written for the four cylinder Turbo Sunbird to control your PFI injectors with forced induction.
