Welcome, tell us more about your car, modifications you did etc
It's seems that your ecu is SFI but for sure look up at manual if your injectors works independent (then will be obd2) or if they work in pair (SFI)

OBD2 OBD1 have 3 connectors and 4 independent working fuel injectors
SFI has 2 plugs and 2 pairs of working fuel injectors

Check the 26pin connector of ecu and if there pin1 BRN/YEL color and pin2 RED/BLU color wires then it is SFI

The injector issue is as follows, the engine has 4 injectors. The stock D14A3 ECU has only 2 signal wires going to the injectors. A normal OBD1 ECU has 4 separate signal wires going to the four separate injectors. That is what we want. On the stock D14A3 and D14A4 the 2 wires from the ECU are splitted in 2 by 2 is 4 wires to the 4 injectors. This splitting is done in the so-called splitter, found above the passengers feet."

So to help yourself to be sure 100% if your car is SFI read this OBD1 swap D14A3/4 (upd.)

Good specs and modifications has your car.
How much power it is have?
Did you swap the IM (intake manifold)? Or is the stock one?
S8G gearbox from which car it comes from? I am asking because I think all the 96-00 civic has s40 gearboxes

Great horsepower makes your engine but how it outputs such number without ecu tuning?
