C34 Ecu Pinouts

[clip14]

does anyone have the c34 ecu pin outs? im looking for the rb25de pinout in particular.

cheers

[chook]

S1 or S2 ?

[clip14]

sorry i'm not sure which series but the ecu number is as follows:

23710 84T60

MEC-R455 A1 6921

Cheers

If you have a stagea with three rows of pins in your ecu it is probabll as per the pinouts in the DIY section above^

[clip14]

nope, two rows of pins, has c34 written on the side of it. perhaps it is an earlier series?

was informed that it is a rb25de ecu which has vct outputs and a 2 row configuration (r32 plugin)

just wanting to confirm this.

Its from a C34 Laurel, not WC34 Stagea.

In particular, a 96 on, 2WD, RB25de Laurel.

Should make a nice paperweight.

thanks for the reply.

does this ecu have vct?

at the moment i am running a r32 rb25de ecu with no vct. if the c34 laurel ecu has vct then i will run a separate wire from the vct ecu pinout to the vct solenoid.

cheers

I think VCT came in with the NEO engine in '98. so I wouldn't think so. What engine are you running ?

[clip14]

r34 rb25de neo.

was hoping to have an ecu solution, but i may have to use a rpm switch to control the vct after all

[clip14]

not worth the cost for just the vct switching. can get a rpm switch for a few hundred.

might go to emanage as i think that has a rpm switch output and is a lot cheaper than a link..

r34 rb25de neo.

If you can manage it get a Vipec or Link ... that will do your variable cam.

Are you aware r33 Rbs5det has on/off cam timing and R34 Neo has variable?

[clip14]

no i didnt know that, when i did some searching, there were mixed opinions about the vct type in r33s and r34s

is there a definitive answer?

[clip14]

thanks for the reply

the engine I am running is the rb25de (non turbo) so the turbo ecu is probably not the best answer.

the r34 power fc is also not a go because i am using the r32 loom which has a 2 row ecu plug instead of the r34 3 row ecu plug

As above

Here is an ecu that should do the job - you would probably get it for $100

Can same 1 please sent me the ecu pinout for the S1 RS4 rb25det? (R34 GT-t Power FC is waiting to go in!)

have searched and all i get is the R34 ecu pinout.

That's the one (in the DIY section above). Works for S1 stageas.

there have to be some pins around the wrong way, like here---->

(Post #8)???

PS. Thats for a S2 Stagea pinout, i need the S1 Stagea:)

That is the S1 pinout. I have the most common ecu #23740 OV300 and I have fitted boost controller, SAFC, SITC, Innovate wide band sensor, speed limiter cut and identified power sources and earths no problem. There are two other S1 ecu types.. there was a long thread a while back by people trying to install aPFC
