I have a dpfi ecu 1990 civic DX and an SAFC. Im trying to figure out where the wires for the tach signal and the map in/out go on the ecu i have a pinout for it, but i just cant find the correct wires.

 

Apexi doesn't list the SAFC install on the DPFI ECU.
I think there is something with the DPFI and MPFI TPS, but I'm not sure.
Never done it, but as far as I can see on the internet searches, you can use the DPFI TPS on an MPFI by switching the wires around.


Anyway, as far as wiring to the ECU goes...
Scroll way down to page 41.

Top left corner 'h1-a' is the wiring for the OBD-0 B16 engine.
It's the only OBD-0 they have on there.
You don't have a knock sensor so skip that connection.
The diagram is 'backwards' from most pinouts diagrams.





You will be hooking up on
A15
A16
B15
C11
C7


Cross reference for MPFI and DPFI show the same pin locations

 

thanks this helps a bunch
