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.

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.

      Mistakes were made, my R34 Story

      Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.

      That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!

      Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)

      Was that deliberate?

      You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
