You will need an ecu that is capable of running MPFI. P28 would be great for a D16Z6, PM7 for a ZC.

Just did this conversion on my hatch, in order to be able to put my turbo on.
Want too hard if you have some wiring expirience and some patience.
If i could make one reccomendation it would be to get a EF Si IM, instead of a EG IM or any other IM off of another model honda. EF Si will be the easiest and most direct switch.
Good luck :)

So where do you wire in the harness for the fast idle solenoid valve? I have the plug and all that jazz I just need to know where to run the wires from.

I am also going to do this swap for my engine before i go with VTEC. But it has been hard finding an actual MPFI intake system.

I have a 91 hatch Dpfi automatic. I replaced b2 motor with ZC 1.6. Now I want to do the conversion to MPFI. What ECU should I be looking for that will work with my AT set up. Thanks in advance for any input.
