nevermind found it:

Ahh so THAT's what these things do. I see them on IM when I search for M35 ECU and wonder WTF are they....

and speak shit it does.

It modifies the speed signal to the ECU from 140kph.

Not sure what the ECU does from 140kph as I couldn't understand it, but there is definitely mention of it changing the "normal" tune due to the "high speed".

Just putting it out there, I know no more than that :rolleyes:

I shouldn't think its secrecy - just easier to email stuff than try posting it on here sometimes. Speed limit defenders have been around for ages they do not harm the ecu in any way. - only JDM vehicles are limited to 180 all your aussie assembled cars can go as fast as their engines will allow so its not so radical. Of course doing 200km/hr down your local highway is irresponsible but there are plenty of tracks where you can exceed 180. Nistune, E-Manage and all aftermarket ecus will get rid of the speedlimiter as wll. Skyline owners just snip the speed signal wire or put a switch in it to defeat it.

Kiwi is correct & its alot easier to just send you an email with all the info (i have translated the japanese fitting instructions)!

Kiwi is correct for C34.

Consider this though, with the "Speed cut defender" option turned on in Scott's emanage (which is installed properly), the ECU's speed limiter still kicks in.

OP is referring to the NM35 install, not a C34 install.

If you have the instructions for install into an M35, then cool.

Im just offering what i know, take it or leave it, i really dont care! I just remember how frustrating it was when i went to install one of these and no-one knew anything about them! Yes the one i did was for an rb25 not a vq35, but the principals are the same; I have a wiring plot diagram of the vq35 ecu & translated fitting instructions (with switch pos etc) for the sld (yes fitting instructions, unless you are psychic and know where everything goes - if so help him & tell me the lotto numbers while your at it)!

There is no speed pulse input in our ecu, the signal goes down the CAN line like I have said. You would need the M35 specific unit and it would just plug into the OBD2 port I would assume, unless you cut the CAN line and intercept the signal, in which case you can forget it, not a smart idea. If you have the wiring diag, take a pic and post it, please. :thumbsup:

So wrong...

So condescending...

Just what is so wrong?

That it is easier to send info as an attachment to an email than post it on here?

That SLDs have been around for a long time?

That they do not harm your ecu (if wired correctly naturally)?

That cars sold on the Japanese domestic market are speed limited whereas your aussie (or NZ assembled) are not?

That 200km/hr on the local highway is irresponsible?

That 200km/hr is possible on many race tracks?

That (some) Skyline owners jist cut a wire to the ecu plug to defeat the speed limiter?

That just leaves the question of the E-manage and after market ecus getting rid of the speed limiter.

I will accept that you have been unable to wire your e-manage so as to defeat the speed limiter and you may be right that it cannot be done with your car although I would be suprised

But replacing it with an aftermarket unit will definitely do the trick.

There is a VQ powered NM Stagea drifter (albeit a manual ) running around here with a wired in Link and that can go as fast as its little wheels will turn.

It has already been explained Kiwi and the VQ30 doesn't have an electronic throttle which is one of the the issues.

To the OP, understand completely what cutting the CAN line might do before installing this device.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
