The 4HE1 engine is a completely different engine from the previous 4BD1/4BD2 engines. The injection seems to be primarily mechanical but there is a computer that is connected that modifies the injection parameters under certain conditions. You can make an analogy to the last generation of carburetors that appeared on gasoline engines before they switched entirely to electronically-controlled fuel injection.
On the 4HE1, a computer is connected to the mechanical in-line injection pump and modifies the operation. From what I read in the FSM, the computer advances the timing under certain conditions, reduces the fueling when the engine temp exceeds a set level, monitors various sensors in the engine and controls the "Check Engine" light, controls the exhaust brake, and generates the ODB codes.
I suspect that the engine would run without the computer, just not sure how well.
