There are three specifications for Civic/CRX wiring 88-91, in my mind at least:

- DPI (aka throttle body injection)
- MPFI (multiport)
- HF (multiport with a bunch of other crap wires that makes a MPFI ECU act wierd and click code 13 until you cut them)

Zdyne is set up for MPFI... which a B16 Civic should be wired for.

No in a 88 std hatch dual point injection it is already wired and runnin with a pr3 just wonderin if i can just plug and play a zdyne with out rewiring again.

88-89 CRX HF seem to exhibit strange problems with the allegedly "plug and play" nature of the PR4 ECU with LS swaps. I was getting code 13 (PA sensor) and my idle would fluctuate when I pushed in the clutch pedal.

I cut these wires:

A6 - EGR seloniod control
B2 - shift indicator
B7 - clutch switch
B9 - reverse sensor
B11 - heater sensor
C8 - EGR signal

Problems solved. Speed PHreak and I think C8 was the code 13 culprit, too lazy to hook them back up and see.
