R31 ECCS ECU pinout diagram

[BIGBLOCKR31COUPE]

Does anyone have an ECU pinout diagram for the R31 RB20det red top ECCS computer. Is it like the older NICS or newer R32 ECCS? Any help would be appreciated.

Thanks,

Geoff.

rb20det.com has a reference guide

Thanks Kinks but it doesn't actually refer to the red top ECCS ECU. The site shows R32 silver top pinouts only.

bummer.. oh well i'm no use then

[BIGBLOCKR31COUPE]

Anyone else have any idea?

Is this one of any use?

Thanks SKY031 but no it's not. I have the NICS one and the R32 ECCS one, but need the R31 ECCS one.

Thanks anyway,

Geoff.

have you checked to see the diffrences between the r31 eccs and r32 eccs!

[BIGBLOCKR31COUPE]

That is what I am trying to find out. I want to know whether it is like the R31 NICS, R32 ECCS or totally unique.

[rsx84]

I'm guessing you have the r31 eccs version, what i was trying to say is have you looked at the r32 eccs pinout diagram to compair it to the r31 eccs you have!!

[BIGBLOCKR31COUPE]

I have already got the R32 pinout diagram and R31 NICS but not the R31 ECCS. This is what I need. Thanks anyway rsx84.

i was talking about taking time tracing wires back to your ecu (which i asume is the r31 eccs). sorry dude.

try e-mailing this bloke

he sent me a english version r32 wiring diagram after i got no help from nissan aus!

[BIGBLOCKR31COUPE]

Thanks rsx84.

Luv the R30. Good to have something unique.

I have one for a hr31 ecu if thats what you want

[BIGBLOCKR31COUPE]

Thanks Dsturbd. Is it the ECCS or NICS one? or are they the same?

Geoff.

[BIGBLOCKR31COUPE]

The reason I am asking is that I am about to help a friend put an ECCS engine into his dead NICS powered R31 coupe. He is trying to keep the process as simple and cheap as possible. We haven't gone to purchase an engine yet and he is worried that he may be up for a small fortune to have the wiring done. If the ecu uses the same kind of plugs as his NICS ecu it will be very easy for us to separate the engine loom from the others ourselves and only replace the one simple loom (the NICS ecu has 4 separate looms with their own plugs) leaving the other looms connected. If the pinouts are like the R32 pinouts we will need outside help. So it would help if anyone knows whether the R31 ECCS pinouts are the same style as the NICS ones.

Thanks,

Geoff.

Think there the same but i can check.. i have a couple of different

diagrams laying around some where ..

[BIGBLOCKR31COUPE]

Thanks Dsturbed

[Dsturbd]

Have the diagram in front of me. 48 pin 3 block sound right

[BIGBLOCKR31COUPE]

Thanks Dsturbd. That is good news. We should be able to do the conversion pretty quickly.

Geoff.
