How do i go about converting over to multi point I have a 91 civic hatch
and its dual ...i converted it all over to manual.but i also still have the auto
ecu will that be a problem to ?because i have heard that 2 injectors work at the same time but i need a box of some sort ..thank you

 

you might as well get a 5speed pm6 si ecu or even a pg7 ecu....btw you need to change the ecu anyway.

 

pick one.

what about the injectors ? dual to multi ? i got a obdo harness

 

Read the links,
basically you need
1) Complete MPFI Intake manifold, all the sensors, injectors the injector clips/wires, from the same year car, 88-91
2) Injector Resitor Box
3) 88-91 Civic/CRX Si or HF distributor
4)PM6 ECU 5spd, 90-91 preferibly can be chipped, the older ones are a bit different. Or PG7 5spd ECU from 88-89 Integra.

Then extend some wires, change some pins in the ECU and you are done.

Read the links for more detailed information.

 

Also just use your STD/DX harness, all you need to do is extend 2 wires and add 4 for the injectors, really easy to do, a lot easier than swapping everything out.

Trust me, I've done this a few times already.

 

did you not click on the links above?? come on now.

 

the mpfi swap is alot easier than it looks just do some research

 

+1 for easy
