unfortunately that's where my knowledge comes to a grinding halt. I don't know what the signals look like on a oscilloscope.

But I gather if you cut the wires going into the tv and identify the hsync vsync and RGB you can match them up from the sync splitter and hence picture?

My problem would be the disassembling of the intricate and deceivingly simple dashboard. Also by doing the above would you effectively brick the cd player? i.e the screen that displays the track number and allows you to select the track?

you have the idea correct. I prefer to scope them so I know what I'm working with. when you do a EVO 8 from dry a scope is a MUST.

the question I thought you asked was how to reuse the screen for a car pc. thats what I do with 99% of the cars I see now.

if all you wish to do it get into it via composite thats easy. TV button, joystick over to teh top rt select VTR - done. make sure you are sitting still and have the handbrake on.

After finding out the handbrake and sitting still, I'll think I'll try wiring straight into the back of the TV, and since the radio has an absolutely useless aerial, It wont be much of a loss (can only get 104.1), I'll just have to figure out how to disassemble the console.

No doubt there would be some info on the web for disassemble and oscilloscope signal identification .

if you are asking about how to get the Xanavi and screen out of the R34 dash and back in I did it yesterday - taking the lot out is about 5-10 min work if you have done it before - installation is a bit longer - here are some random pics I took of the process - there is a good HOW TO on the SAU site - the number of connectors looks like a nightmare but every one only fits in its proper shaped place so it is not hard and Nissan gives you enough wiring to reach everything easily (compared to bloody Holdens etc where the dash wires hardly reach) - use cardboard to protect you trim from scratches from the mounting frame when you pull it out as a whole - it has sharp edges

if you work out how to connect the existing screen to a modern DVD player (bypassing the Xanavi HU) I would be very interested to know how to do this also !

Can someone post the link to xanavi screen removal if they know where it is?

Sync signals on oscilloscope,

The CSYNC output should look like this:

---_------_-----_-----_-----_-----_-----_---

And once for every field (once in 1/50 or 1/60 second) like this

---_------______-_____-______-----_------

But what about Hsync and Vsync

r32,

ok now you know know what you are looking for- go play. teardown is two posts above.

KV2,

google is your friend. I've given more than enough info to sort this without the xenavi box in place.

I wish I had even a 1/4 of the technical expertise you guys got so unless its dead simple even google won't be much use lol - I just installed a replacement Xanavi HU that worked that I got on weekend for $50 with other gear for a problematic one - no special expertise needed for that, just common-sense

useful for this discussion. most of the Xenavi stuff runs active high CSYNC. there are variants that have H&V separate. then there are ones that bury it in a color jut for the hell of it. mitsi is good at this.

KV2,

electronics degree helps me. I have been dabbling in electronics since age 11. (I'm 38.) theres not a lot I will not attempt to crack/modify.

have a crack. make sure you have at least a 40 Meg scope sitting beside you.

I would still make use of your friend google for what video looks like. some of the stuff back there will look a LOT like sync signals and its NOT.

Anyone able to tell me how to wire in a ntsc to pal converter ?

Im thinkin plug the reception inputs into the converter, then plug the output of the converter into the xanavi computer in the boot ?? sound all right ?

Does anyone know why the lcd screen plays up ?

Is it problem in the computer, problem in the satnav controls or problem in the actual screen ? Ive noticed that the lil japanse error message changes when I put a cd into the dash

so that leads me to belive that the problem isnt in the screen, perhaps in the satnav unit

usually mine works first pop but ive noticed that sometimes it wont.. it will sit with the error screen, and then start working about 10-15mins later. seems almost as if its the system not letting it start.. in which case that should be able to be tripped to ignore those error signals..

any ideas ?

Oh Ive also noticed that behind my satnav dash controls I have this lil box wired in which has TV(something) written on it..

and some words saying.. for the ease of viewing of tv for you and your loved partner (gotta love that Japanese english hahah)

is that the actual tv tuner box or could that be a wireless unit for a remote control ?>

if its a tv tuner, could i just rip it out and put in a pal one ?

OH I did the ol channel scan using one of the on screen options and I picked up the audio for New Zealand TV3 (im in New Zealand) So I know I can get TV, just need a frequency booster or somthing to get the video.

Can anyone tell me the order the red black white and green reception plugs connect into the computer in the boot ?

cheers!

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      No, you're wrong, and you've always been wrong about this. The Nismo has 2 sets of openings. One is a real 2-way, and the other is a 1-way. There is no 1.5-way possible with the ramps that they offer. A real 1.5-way does exist. That Cusco stuff I posted is a prime example. If the forward drive ramps are, say 55°, and the overrun ramps are, say, 30°, then you will get about half as much LSD effect on overrun than you do on drive. It is real, it realy works. OK, you're slightly right. The Nismo has 55° and 45° ramps on the 2-way, so it does offer less LSD effect on overrun. But, I think that just means that they've (probably) sensibly established that you do not want actually equal LSD effect on overrun. You just want "quite a lot, but not quite as much as the drive LSD effect".

      Nismo GT Pro LSD configurations

      By Kinkstaah · Posted

      Yea, that is what I was getting at in my ramblings too. The nismo one actually is a 1.5 way and a 1 way. They don't do a *2* way because a true *2* way would have equal ramp angles. Or is that a true 1.5 way? Realistically I think a "1.5 way" does not actually exist. A diff can either lock in two directions or one. It also doesn't help that a LOT of people in Australia speak about 1.5 way diffs are referring to their 1 way diff.

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.
