Need An Ecu Pinout Diagram

[Cobey]

Hey Guys,

i'm about to do some aftermarket computer wiring and i need to know the pinout diagram for our cars, does anyone have one?

or know what car has the same ecu pinout (350z)?

Thanks in advance

I've got the manuals for the 2003 Infinity G35 coupe. Loaded them onto www.stagea.info forum as many bits similar to our Stageas.

But I do remember a couple being too big to upload and the EC PDF was one of them.

PM your email address and I'll send it to you, if your email can handle nearly 27Mb of file

I can get manuals for other year models if you like, but not sure if there will be any/much difference.

Do you care to elaborate what you're up to?

[Cobey]

Well for starters speed cut is going. Giving me the absolute shits. I'm also outing in an aftermarket afc. And looking into various other piggybacking options before I buy my link ecu.

But mainly cause I'm about to get into the "real" modifying my car.

I'm also about to pull my dash apart in the next few weeks. Anyword on the tv tuner? And cruise control? I'm about to make a hell of a mess. :-)

And Leon, I'm putting 12's on the rear now. To ensure I have enough traction, for future mods ;-)

If you go standalone you wont have a speed cut, the speed signal is probably transmitted down the CAN line and not a speed signal wire (ours is anyway). Hopefully the standalone works well and you don't loose too many functions like dash, abs etc. At least you don't have to control an auto and attessa...

What sort of power are you looking for? Perhaps a VQ25det is the go.

or maybe a vq35dett? i have a pivot speed meter v to try and remove the speed cut?? weather it works or not.

ill be going a link ecu in the future.

Hey Cobey

I think getting it from here http://www.sendspace.com/file/302wnc will be easier and other people might like to download a copy also. This link may not be active for more than a few weeks tho.

About page 103 on the file it starts to get into what you're after, I think. There's a table there listing every pin, wire colour (applicable or not?), what's it used for and what you should see if you measure it with a multimeter or CRO.

The AV (audio visual), AT (auto transmission) and BL (body, lock & security) files are the only others that were too big to be uploaded to www.stagea.info but I can post links to them if anyone wants them.

RE TV tuners, they will be here as soon as my Chinese friends finish partying for their New Year. About middle of this month they tell me but I'd add another week for slow shipping.

RE Cruise control, I received a sample that has all Jap instructions in paper version that won't translate when scanned & copied into online translator. So that's gonna be interesting. However, it isn't the type that will work as factory (buttons on steering wheel) so it's going in my X-trail and I'm back to hunting down my previous number 1 choice.

Look forward to seeing your 12" rears. Seriously? you've gotta be kidden'

Hey Leon, thanks for that.

It looks same as the G35 one, you sure its JDM specific?

Cheers

It looks the same as the G35 because it is so I'm not sure if it's exactly the same as the V35 but hopefully it's close.

Apparently the US ECU is different to our JDM ECU.

[scotty nm35]

I wonder if a G35 full wiring harness and aftermarket ecu from the US would work, do they run the same dash setup? ABS may also work the same.

With a link ecu (or Haltech ps2000) you should be fine, you may have to leave the stock ecu in place also. Cable throttle would be a must although the Motec 800 can control the stepper throttle, pity it costs so much. Do you have a good tuner?

[Cobey]

yeah ive got an awesome tuner.

yeah its going to be a bitch with the throttle. oh well ill sort it.

not a motec man :S

[daisu]

Any chance we can get that file up again please Commsman?

[Chris Rogers]

luke ,

swing past and bring a stick with you. I haev most of htem here.

[daisu]

Thanks Chris,

I pulled the pedal out and checked the sensor with my multimeter, both sides seemed to be working.

I'll come down on Friday and see you.

[Chris Rogers]

if you can get it to drive here I will plug into it. that will give a definitive answer as to why its doing what it is.

[daisu]

Unfortunately it is completely stranded in the driveway, absolutely no throttle (idles only).

A friend is lending me a throttle on Friday so hopefully that will shed some light.

I'll still come down and see you though.

[Chris Rogers]

no probs. if I have time I'll put the launch over it.
