Well my car is a 90 Si so I don't need any info on converting to multi-point. What I want o know is if I can splice wires into the ELD system (PM6) on the ECU since the PW0 does not use them or should I tape off those pins and add new ones? One other thing I see is that the Purge cut-off solenoid valve is in a different spot too. Should I worry about this or repin it? Here's the info I've found so far. Thanx in advance


VTEC pin assignments:
Pin A8==Spool Solenoid Valve (grn/wht)
Pin B5==cylinder head Oil Pressure Switch (blu/blk)
Pin B19=Knock Sensor (wht)
Pin C8==2nd Oxygen Sensor (orn)


USDM "Si" pin assignments:
Pin A8==Nothing
Pin B5==To Alternator (part of Electronic Load Detector [ELD] system)
Pin B19=ELD system
Pin C8==Nothing

Misc. wires

pin A6==**JDM ** Ground, **USDM** Purge cut-off solenoid valve


pin A10==**JDM**Pressure regulator **USDM** Nothing, (HF)EGR activation
cut-off solenoid valve

 

get the pw0 or pr3 ecu diagram and match everything up. Take the time and match your purge valve. Also You should only be adding one actual pin to the ecu for vtec solenoid.

 

Oh ****. That must be why some b16 swaps throw an ELD code. I dont knwo what to do about it though.
