ok well this weekend, i was successful to two things. i successfully put my turbo kit on the car, but unsucessfully did the dpfi to mpfi swap. heres what i need help with:

in the instructions, it says that pins B10 & B12 are empty, B10 was but B12 wasnt. it had a white wire with a red stripe coming out of it. what should i do?? also the wires i extended from C1 and C2, where do they go? C1 goes to the blue green wire and C2 goes to yellow blue, where are those wires? got any sites or pics of that part.

also on the DPFI TO MPFI swap, does anyone have any diagrams of the intake manifold to show me exactly where all the hoses go?

finally, i have the walbro 255 fuel pump, where do i get access to the stock fuel pump, i took the seat off but could not locate the pump. need help with that.

the car wants to start but it seems like its not getting the right amount of fuel due to (what i think) the wires not being in the right spot? any help is great


if anyone who reads this lives in or around fort wayne indiana and would be will to help me next weekend, that would be AWESOME!

thanks and hope you can help me out

 

ok first off make shure u have these things...88-91 civic/crx si intake manifold,distributor,and ecu(other variations can be used but these seem to be the simpelist).also make shure u are using obd 0 injectors with a resistor box.
the wire in b12 is just extra put some tape around it tuck it away somewhere.the wires in c1 and c2 need to be ran to the 2 extra wires that the si dist. has and the dx dosent.as far as vac. hoses i put the big red one on top of the intake man.,the one that goes to the map sensor on the back of the intake man., and the one that goes to the purge valve(think that what it is called) to the littler pipe sticking out on the top of the throttle body.

 

yea i have the si distributor but do i need the si ecu? i can get one but short on money. let me know if its nessacary with the dpfi to mpfi swap

 

Hell Yeah you do. The DX ecu only controls the primary and secondary injectors, or 2. The Si ecu controls all 4. It's the biggest must on the list of stuff to change. While you're at it, get a 90-91 PM6, it'll cost more now, but you can chip it later for better tuning of the turbo setup...

btw, you don't need obd0 injectors, obd1/2 are easier because you don't need the resitor box, you just wire straight to the injector. That's what I did...

These are the instructions I used...

 

i tried using obd2 injectors with out a resistor box and my car would barly run,other people have tried obd1 and had similar problems,if it works for u(thumbs up)but it didnt for me .

 

right now on ebay there is a crx si pm6 computer for $30.00. type in keyword crx.

 

i just got a si ecu for free so im set i think

 

hey one more thing. when i cut off the 2 injector plugs on my dpfi manifold, there was one yellow black wire from each plug. i know those go to the resistor box. but then i found another plug that wasnt going anywhere, it had a green plug on it with a yellow w/black stripe and black with yellow stripe. it was unpluged from right underneath the front injector. do i also soder these into the resitor box. or what is this plug for? where does it go?
