Hi,

I have been searching high and low, with no success (including on mp3 car). I was wondering if there is anyone who has installed a Computer in their v35 (or M35 I guess) using the standard navigation screen as the computer screen? and what video card you used?

Everyone I have seen, has replaced or added an extra screen. I wish to use the standard screen. I can find video cards that output in NTSC, but was hoping that someone else has explicitly gone down this path, and the experience they have had?

RGB with 60hz sync refresh. unsure of the data stream needed to fire it up though.
I am using the Composite In, into the TV unit, using the cable I got from you. There are a number of video boards that do NTSC (60hz), but I also read of people complaining of various "issues" when going into a TV, directly from a computer.

I have seen on YouTube people using the TV out from windows mobile phones using composite, and it looks good (eg http://www.youtube.com/watch?v=WjnABOFkJZw&feature=related). My home computer also has a video out (S-Video, and composite adaptor). I have plugged it into my Plasma, and apart from the fact it was set to hi-Res but TV is lowres, it looks good, But I don't know how or if I can switch it to NTSC, or if it is actually even outputting PAL; I think my plasma switches automatically, it appears to when I switch my set top box between PAL and NTSC.

I was hoping someone else has done exactly what I plan to do, and therefore could recommend a video card that is known to work, well.

I basically came to record the answer in case anyone else is interested.

Because I am using the NTSC video in, the actual resolution is controlled by the NTSC standard. Looking on Wikipedia

Each frame consists of a total of 525 scanlines, of which 486 make up the visible raster

That's the vertical resolution, and there are all sorts of opinions on the actual horizontal resolution (its analogue), so I will be running my display card at 640x480. Which also aligns exactly to my phones resolution also; which I will be viewing on the screen for navigation (TomTom), and I will also be interested to see a little phone app I have that plots and records the G-Forces.

ooo... almost forgot, I am using a "HIS Radeon 9250" which I bought from a shop for $65 (sells on eBay for less), It allows you to chose NTSC or PAL, set the refresh rate (60hz) and resolution, move and size the picture around the screen to make it fit. I have tested it on my home TV which allows me to specify to only accept an incoming signal of NTSC, and it looks good. Haven't had the chance to try it on the actual car's screen yet.

I have it all up and running at home to my plasma screen, using a cheap power supply. Its now really only connecting it all up. I have no idea how I would feed the wire from the battery all the way to the boot, and from the boot to under the dash or to the center console (USB). I have also purchased a reverse camera (CCD) which will need the wires fed up from where my rear plate is up into the boot.

This long weekend, I will just "test wire" it all up (ie cables running outside of car), and get the final install done by a professional, possibly at the same time I get cruise control fitted. I think most places would either be not interested or overcharge heavily simply to route wires through the car (ie no expensive hardware). Its going to be hard to pull it out if it works, and my Blazt OBDII cable also come in time,

You'd be surpised at just how easy it is to lift up the trim along the door sills and lay wires there. Even removing the centre console or glove box area is just a few minutes with a philips head screwdriver. Plenty of DIY guides floating around (G35driver.com) or PM me if you want some pointers.

I bet you're not located on the Gold Coast or in Brisbane. If you were I'd catch up & give you a hand. Oh, and hold off on the cruise control for now if you can. I'll be taking EOI on some in the very near future.

Its not so much the trim inside the car, more so getting the wires from the engine bay, into the passenger area; and the cable from my reverse camera into the boot. I will look at it a little more closely this weekend, because, as I said, if it all works, its going to be damn hard to disconnect it...

Thanks for the offer, I do live in Sydney, and I will look on G35Driver for specifics (and hopefully photos/instructions) on routing wiring

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
