Ok, heres the deal. I bought a JDM D15 VTEC that came with a 90 or 91 SI manifold on it. I ended up putting that into my CRX with a rywire obd0 to obd1 conversion and a chipped P28 (uberdata d16z6 basemap). I have a D16z6 distributor. Injectors are from a mid 90's honda (therefore I dont need the resistor box). Did the multiport ocnversion, really confident that it went well. The only thing that Im not too sure about on the wiring is what way the crank angle sensor wires get hooked up, but I have tried either way and it doesnt really seem to help much.

The car doesnt run smooth at all. I messed up the injectors in the begining, got thsoe figured out, had the IACV plug disconnected, fixed that.. still nothing. Tried a different known good dist. tried that, still nothing. I tried a friends P28 ECU with a B16 turbo basemap on it, and it ran good (although misfiring on one cylinder it seemed) for a little while. Shut it off because I thought the misfire was from the crank angle sensor being connected backwards. Switched it around twice since then and the car doesnt seem to want to start anymore. At this point Im at a loss. Please help!

Before the car would idle really really rough. you would have to be feathering the thorottle on and off to keep it running but when you gave it soild gas it would just die. Im so confused as to what it could be.

 

dizzy wired right?

 

if the dizz wires added (cpk) need to be soldered on solid. when I had mine half ***, it had the same prob. also, any codes not cleared may result in this prob

 

I have been periodically clearing codes. The wires are all soldered and I used thick gauge wire. Should be more than enough. Ill check the wiring on the dizzy plug again to make sure that its right. I dont really know those abbreviations very well though...?

droppedcrxsi, your harnesses dont include the re-pining for the multiport allready do they?

edit: There is two yellow wires on the the dizzy... I had forgotten about that. I think that they were a different gauge though, so they should have matched up because of that right?

Thanks again!

 

Personally, I think you're fucked. You should sell it for $200 to the first person who offers. (inside joke)

So Jeff its not even running now? What about my dizzy, you didn't break it did you? On the dizzy, the thicker of the two wires seems to be the A21-ICM on the far left in that picture.


I've been helping him with this, but my same swap went fine. I'm guessing it has to do with the obd0 intake/throttle body. I dont have all that much time to diagnose it, so we're kinda stuck. Honestly, at this I would suggest making a continuity tester with a longass wire & aligator clip, and checking *every* important sensor wire, from the sensor connector all the way back to the ecu plug.

You have to send in the harness if you want dpfi to mpfi

 

yeah.. i can **** out more than $200, but thanks jeff Anyhow I think I'll try and resolve my issues on my own first. I think that its probalbly a combination of things right now. I might just pick up a D16z6 intake manifold and sensors and give that a shot. Let me know if anyone else has any other suggestions. I'll have to check the dizzy wires otu once I regain motivation on this project. For now its just going to sit till next week.

 

bump...
