Anyone Know A Fix For This?

I have searched the entire forum before asking this, aswell as UK skyline forum.

My new nismo meter set won't read speed correctly ( ie shows im doing 120kph when im actually doing 50 kph etc ) and HICAS light stays on.

I have done the following so far to fix these problems :

1. Fit a brand new speedo cable.

2. Checked oil levels for HICAS

3. Changed over speed sensor as the back of dash for orig cluster that was working fine.

4. Checked Battery power level, which is a dry cell optima yellow top with plenty of juice left in it.

The nismo set is meant to be plug and play.... Don't or shouldn't need calibration or a addon gear reduction box etc.......

Also speed reads correctly via Apexi power FC hand controller LCD display .......

are there any skyline guru's out there that could possibly shed light on this situation.......... or offer a solution.

I won't take it to nissan for them to charge me countless hours for them to try and find the problem and come to the same point as me nor a exclusive over priced performance shop that I will shell out

$'s for them to try and find problem with no solution.

any help would be greatly appreciated.

No speed means your HICAS mucks up fix speedo and all will be good.

Edit. opps sould have read the hole lot frist. When my speedo didnt work at all i had HICAS problems maybe yours is reading that the car is always moving so it has no idea whats happening.

what would cause that?

also can't be speed sensor becuase apexi power FC hand display ready correctly... which gets it information from the speed sensor right....

Also power steering is still 100%....

there must be one person out there with a solution..... seriously.

while i was searching for an answer to your problem it occuored to me that the magnets on the needle of the cluster still use 12 volts, regardless of whether it is a standard skyline cluster or not,

which means that a standard speedo drive would under drive the needle giving the incorrect speed, also hence why the hicus is having issues because the speed is saying one thing yet the sensors at each hub are giving conflicting information.

the reason i say this the early nismo gtr's had 260kph speedo's not 320kph like the later gtr's, mines a november 92 gtr and has 260 on the clock. i suspect the speedo cluster you have there is for the v spec model.

the speed sensor at the dash is moved within the speedo itself and then sends electrical pules that hen allow the ecu to kow the speed, hence the fc handheld LCD is showing correct speed.

I checked with nissan dealer about the part number, which they said was for a 1990 r32 GTR......

aftermarket nismo speedos are pretty standard for GTRs and the like.

I already have a aftermarket 260km/h nismo black dash that works perfect on my R32 GTR.

any other suggestions....

There should be two speed sensors - one is part of the cluster the other is part of the gearbox...Find out which one your (working) Power FC is connected to (i.e. gearbox speed wire or dash speed wire) and then you will know which one is playing up.

nah, 32's only have the one, at the cluster. they have a cable driven speedo.

Thats what I thought.

I'am just at that point of I don't know what to do. It works somtimes and I have replaced the cable.... and the apexi handset reads true... so the speed sensor is fine.

what else could cause this?

there must be someone in Australia with an idea.

      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
