I have a 94 civic Coupe With D15. Can a CRX Si ECU work in place of mine and will it do any better??

 

a CRX Si ECU will not work because it has 2 more injectors and it has different distributor wiring.

Do the DX- SI Fuel Injection swap first then youll get the 15 HP increase and intake sound. You need the Si manifold and fuel **** tho...
Let us know fi you wanna do that then post here and we can tell you what you need or search. DX-ZC swap

 

dual point fuel injection ended in 91. his car actually has all 4 injectors. the crx ecu will not work because it has different wiring all together, and the ecu plugs will not fit together.

please post these questions in the EG civic forum, as your car is an EG. thanks.

 

no offense but he's referring to the 94 dx engine which are all multipoint fuel injected(4 injectors). The ecu's are probably pretty similar in fuel and timing but it will not work due to the fact the ecu plugs are different. If you really want to do this you will have to find an OBD1 to OBD0 harness, get 4 88-91 SI/HF injectors, get an 88-91 distributor and rig it and get a resistor box. Don't waste your time, if you want more power out of the ecu try http://www.hyperducktuning.com they have some good sohc programs for the ecu.

 

ya man early morning for me. My bad ya OBD -0 and OBD-1 dont mix. I usually think if someone says DX in a EF/CRX forum it would be a 88-91.......
