V36 Speed wire


Recommended Posts

Im trying to fit an analogue cruise control kit to my 07 V36

Does anyone know where to find an analogue speed sensor wire for an 07 V36?

I've searched high and low through many g35/g37/j50 FSM and cant find any wiring remotely close to the JDM Skyline cars.

I've also searched on here to no avail.

Any help would be greatly appreciated.

If you put cruise control into the search box you will find a couple of Stagea owners have done it on their NM35s - ok not a V36 but still drive by wire...

When I mention I've searched the above FSM, they all show a red speed wire going to pin 28 @ the a/c amp/unified meter, (for the trip computer data) but my(our JDM) cars dont have the same wire in the same spot, which I was hoping if anyone else had come across this and solved this problem.

Yes I know of this, I have done this in my Stagea, and now wish to do the same in my V36.

I know I'm a bit late to this party but since people have been nice enough to help me out with a question earlier this week, I thought I'd contribute to this one.

Not sure if you've had any luck since but most certainly one of those wires going to the A/C and Instrumentation Amplifier will be your speed sensor. The only way to be truly sure though is to grab an oscilloscope and measure the waveform. I haven't got the FSM handy on my laptop but when stationary, the signal should either be constantly high or low and when in motion, you should see a pulse train that increases in frequency proportional to speed (you'd need to have the rear wheels up in the air or on a roller dyno of sorts to confirm this though). Basically, the pulses should start to pack together closer as speed increases.

That's how you'd find it without any reliable documentation. It's similar to the park brake wire (also going to the same unit) I had to find for a device I built, where it wasn't in the place the FSM indicated, so I had to sniff it out with a multimeter and see which one changed between active low and high.

I haven't had much luck yet; Been a bit slack and a bit nervous probing back there even though I do have some US FSM.  I was even given a probe extender (a wire with a sharp point on one end) so it would make the job easier.  I just have to get the courage to get in there and test it for myself.

    • He could just take the Bogan Cruise Ships setup... Already got a good setup, with blower, the auto was rebuilt too wasn't it? Perfect time for him to upgrade the tailshaft, diff, and axles...    And wouldn't need to waste money on redoing the Commos seats, as he could just buy race seats for the 5...   As a highly modded car he could avoid the ability to give it away to offspring too when they crash their cars...
    • It's really interesting how much it's moving left to right, and doesn't appear to be actually spreading. For this to be moving left to right, without flaring, means unequal forces being applied until equilibrium hits in one way or another.   Reasons it could be unequal; Piston sizes left to right are different sizes. Only minute differences. Pistons moving on different planes. That is, are they moving directly straight at each other, or slightly out of alignment. The fluid is restricted getting to one side.   Some tests you could do. Pull the bleeders on the left and right, fit each side with pressure gauges. It will allow you to make sure pressure is equal (and really, it should be as fluid flow is so damn low, so fluid flow dynamics shouldn't come into it).   With the calipers off the car, have both sides retracted as far as possible, measure very very accurately (think micrometre) distances between opposing pistons in four different spots per set of pistons. Firstly, on each opposing pistons pair, the measures on for different spots should be equal. If it's not, and especially if one spot appears to actually get closer compared to another, the pistons aren't aligned, and now the forces left to right won't be equal, as they're the forces fighting each other.   You can also pull all the pistons out, and very very accurately measure the diameter of them. If they're not equal left to ight in the pairings, and especially if the area of the pistons on one side is different to the area on the other overall, it'll all be out of whack.   My bet, is shit QC in making sure the pistons move in the same plane left vs right. Some minor out of square machining, and nothing will line up, things will want to move around.
