red civic

I have a 90 civic hatch DX, 1.5 liter non vtec, I swapped this out to a SOHC vtec 1.6 liter. I used a 91 Si wiring harness and a 91 Si computer, but didnt change the inside wiring harness. Does anyone know what wires i need to change at the ECU to make this work?

Any information would greatly be appreciated.

Thanks

Use your DX harness and modify it. Its easier to do that than to use the Si harness.

check your plugs and stuff, maybe its flooded. double check your plug wires and rotor position.

Put a timing light on it and get someone else to crank it over.. You might have the 2 blue wires reversed when you wired up the dizzy and that will throw you ignition timing wayyyyyy out..
