Wiring help

[legacyo13]

I'm swapping parts on my d15b2, I'm throwing a y7 head and an si tranny. I was wondering how the wiring would be to wire up an si ecu. I've searched and never got a real clear answer. So any help would be nice. Thanks in advance.

the only probelm would be the dizzy wiring, assuming your gonna use the IM off your surrent motor.

you need to remove the wiring from the inside of the y7 dizzy and put the wiring from inside yours into it. thats the only wiring thing that should be different.

You'll need to change from DPFI to MPFI. Then you'll need to use a 88-91 Si distributor. You'll also need to get 88-91 injectors from an Si. Here's a link to wiring:

why are you wanting to run a vtec ecu on a nonvtec head?

The d-series si wasn't vtec'd. I'm looking into wiring a pm6 up which is a non-vtec si ecu.

ah, yes, i forget about that one.

wasn't that a dohc motor though? if so, that ecu won't work.

I believe it came with both. I'm not sure, but it's two different ecu's form what I've seen. But my friend had one on his car before he wrecked it. But he's got 3 on him. That's his second ef this year.
