hey im putting this d16 motor from a 93 ex civic in my crx. I have a pw0 ecu i want to use. what rewiring i need to do to use this ecu or should i get jumper and use p28. thank

 

What CRX do you have? (DX/HF/Si) If you have a DX you've got a little more work ahead of you: MPFI Conversion.

If you plan to do any proper tuning then you should go ahead and convert to OBD1 and use a P28 or similar ECU.

yup agreed....

 

i second that, just do it right and convert to OBD1. You'll need to either swap the plugs over from your distributor onto the Z6's or use a distributor adaptor. Also get an ECU adaptor for the P28. You'll also need for wiring a subharness to connect the VTEC solenoid and pressure switch and a 4 wire O2 harness. If you have an Si you can reuse your injectors and resistor box or delete the resistor box and use the Z6's injectors but will have to solder on the obd1 injector plugs. The only other thing is you'll have to extend the wires for the fan switch from the back of the block to the thermostat housing on the Z6.

 

im using a hf crx. ok u said i can use the si injectors i got that part. im a little lost on the wire to extend the fan switch to the therostat. so i spilce the fan switch wire and contect it to the thormostat?

 

maybe theres a guide out there i can follow?

the cooling fan switch on a crx is mounted on the block next to oil pressure switch
and z6 is mounted on a thermostat housing, you just need to extend the wires.

 

ok i understand that now

 

im still having problems hookin up the fan switch i dont konw what colors they are. thanks

 

bump

 

After all that ecu talk I'll let you in on a secret.

Send your ECU to CRX Toad and have him chip your OBD0 ecu to a P28 spec (best thing to do in your situation). His signature has a link to his site with prices and what he can and can't do. Tell him I sent you.

 

what color are the wires on the for the fan switch on the crx?and were on the d15 do i plug into? the brown sensor? ty

The sensor will look like that. Notice you have 2 prongs, you will have 2 female recepticals with a grommet over it.

Honestly, plug everything else and look at whats left over and do the math...

 

ok ty for help but i kind of new that part i need to know the color of the wires that pluged into that. for 89 hf

 

I don't know why you want to know the color, they are all plug and play. You litterally can't mess it up unless you have something wrong with your wiring, or your engine.

 

i did this swap it was easy. good luck!
