Storm RX7 FC Turbo II Wiring

[JohnC]

Hi all

Bit of a noobie to ECUs

Im nearly finished making up the harness for my Link Storm for my 1991 FC RX7 turbo. 

 

Just wondering about bout the last couple of wires on the list. Do I need the following which I have underlined?

Circuit opening relay - input 

pressure reg valve solenoid  - output

port air solenoid valve - output

solenoid valve (switch) - output

solenoid valve (relief) - output 

 

I have removed all the emissions stuff on the engine  OMP will also be blanked and tuned out  

 

Cheers

You will need the "Circuit opening relay", this controls the main relay that supplies power to fuel pump relay and injectors etc.  This may not need to be connected to the ECU but it will need to be connected to something.  You will have to research how the circuit works in this car or post up a schematic and I can advise.

I cant find any info about what the "port air solenoid" does - I suspect it is emissions related but dont know.

The PRC solenoid is not needed, this would have originally been used to increase the fuel pressure during hot starts.  Get rid of that solenoid and just connect Fuel pressure reg hose direct to manifold.

The other two solenoids controlled the Air valve so they are not needed either.

Thanks Adam. I did end up finding out a little more about the circuit relay. Thanks for backing it up. 

 

To confuse the situation my car is originally an auto but the previous guy swapped it to manual. 

 

Here is a link to the wiring diagrams

and attached what I believe are the correct pages. 

Charging/Starting for A/T

then for M/T

and also Engine Control 

 

Thanks again
