This SPI (TBI) ecu can NOT run 4 injectors.only 1 injector. (there is only 1 injector driver transistor in the SPI ECU) ok?
, you have the wrong ECU. and wrong Throttle body and wrong intake manifold.
you need the 4 injector ECU. that does not exist in 1992.... Ive no idea at all what intake that car has now but is not 1992, for sure, (have the parts book I do on it)
a rising rate, fuel pump , sure know that well. and why. (5PSI boost?)
you are trying to get 4 MPI injectors to fire from 1 injector ECU, why attempt that?
sorry for your , grief and problems whit this car.

Engine is spi, but previous owner installed flange to mpi intake and run on custom ecu.
I don't want go to spi because: i don't have spi intake, and second, the car have high preasure fuel pump, working with mpi so i don't know that it will be work with spi.
I think that change spi to mpi was declared lean mixture on turbo.
Only in 3 weeks I will see the car and check the sensors, if I still do not have an injection signal from ecu I will use the ignition signal and connect to the piggyback, he can control the injection in full group, just for test.
