DPFI to MPFI. Can I use a OBD1 Distributor, and rewire it?

Can I rewire a OBD1 distributor to OBD0 and use that for the MPFI swap.
I will be using the 91 civic si ecu.

no. OBD and non-OBD distributors operate differently.

The difference is that the obd0 fires 16 times a revolution and the obd1 fire 24 times a revolution.

I know there is a way to change the program on a chip to compensate for this.

But i don't know anyone that's doing it that way.

ive seen an ef dx with a z6 swap and used the obd1 dizzy and pm6 (obd0) ecu.

it may have had the internals of the obd0 dizzy though
