im doin a mini swap on my 88 ef with a dual point i need some help i got most parts but got some questions....... i got the p28 ecu z6 head and intake and i ordered a obd0 to obd1 jumper soo all i need is a z6 diz an diz jumper and what else? can i use my d15 plug wires on the z6 i read that you can there just tough to get clicked on and are the z6 plugs same as a6? bare with me im new to this appreciate all help message or email me.

 

I assume you converted to multiport injection already. You need obd1 (saturated) injectors and bypass the injector resistor box (if you have one) or you could fry the injector drivers in the ecu. Its been awhile since Ive done a conversion, but other than that I think everything else is compatible electronically.

 

Us I got Crx si resistor an fuel filter an rail don't you just wire injectors to ecu he said were gonna use the dpfi harness

 

if you are using a computer that is '92+, u cannot use the resistor box or the accompanying injectors, you must match the type of injectors to the ecu. In your case you would likely grab injectors for a 92-95 civic and bypass the resistor box. All the box does is go inline between injector power wires and injectors to tone down the voltage going to the injectors. Saturated injectors (92+) do no require the box. Neither does the computer. and yes you are correct, it is easier to convert the dpfi harness to multiport because the multiport harness will not plug into the chassis harness.

 

if you google, you will find many writeups on dpfi to mpfi conversions and also obd0 to obd1 conversions. there r many that will take u thru step by step. take your time. dont skip any steps. the car will run like factory.

 

Do you no if I can use my single came zc plugs an wires for vtec
