I have an R33 Skyline GTS-T Turbo automatic.

Anyone had a problem with the tacho (RPM) part of the cluster not working properly?

Mine seems to gradually run clockwires from 0 all the way round past 9000rpm over the space of about an hour. I have tried to obtain a second dash cluster but I cannot seem to find one cheap. It has worked once or twice at times, but very rarely.

Is this an issue with the tacho, or the connection?

Anyone know where to get a dash cluster fairly cheap?

Thanks.

Pull out the instrument cluster. you have to take out the plastic dash shroud that covers the steering wheel, and the one around the aircond/deck. There are 3 plugs so dont worry about not being able to put it back together again. Unplug and reconnect. You may want to check the connection running into the ECU in the passenger side kickpanel...this is held in by a bolt so doubtful that its that.

May be the actual tacho itself, surely you can just buy a replacement tachometer and slot that into the intrument panel instead of buying the whole lot. you could probably give it a crack yourself and if you run into any problems go see an autoelec.

Pulled out the whole dash, checked all the connectors to make sure that they were all securely conntected and replaced it all.

Still not working....

Anyway, because there is power going to the tacho I really dont know what is going on, the tacho is still moving slowly from 0rpm to over 9000rpm over the space of 1/2 hour.

Obviously the tacho is working on some level, idle and running of the car is fine, I just got no idea what rpm I am doin and it is really starting to bug me.

Thanks for the help, guess only other solution is to try another tacho, cluster and see if that works.

mine does what yours does too, and fcuk, it is the most annoying ever!!! Its almost comming to the point not im just going to leave it faulty, and run an aftermarket 3 3/4" tacho.. seems like a better idea to me.. plus might be cheaper!!!

let me know if a new cluster fixes it though..

I had (still have) problems with the speedo which is a common prob due to wind backs.

Goes straight to 60km/h weather your doing 10km/h or 120km/h

I wasn't going to spend money fixing it when you can get an APEXi RSM instead.

Exactly what i did and i love it :D

Good for those 0-100 times too. and removes the speed cut.

..and looks sexy!

Probably get one 2nd hand for $250 maybe?

But yeah, has revs too and mine is just velcro'd inside the dash

Plus everyone knows having a quick glance at a tacho or speedo neddle is easier to recognise to the brain than a digital readout. Plus a tacho with its needle design looks heaps better when you rev it up.... Its like almost there, almost..... yeah redline....

True, but when they check it if i get pulled over it goes to zero whcih is correct.

Hehe :D

Plus i can get rid of it if cops are around.

Rip it off and hide it under something (unless they search the cabin off course)

Also, you can set it up so the ecreen will flash at any rev level you want.

One bad thing i don't like about it, which doesn't happen very often, is the sun glare off the glass/plastic face. Normal speedos don't seem to reflect at all so you can always see the speed. Not so with the RSM, but definatley livable.

Definatley a cover up option like you said, but so good at it, i aint fixing the speedo.

it happens to mine, but what i did was i pulled out the whole dash bit and if you pull back the front back of the tacho with all the numbers on it tap the unit behind there or check the wires.. i hit mine and had it connected still with the car running and it starting working again.

Wow, might just try that, I had the tacho out yesterday and once I got it out and checked the connectors to see if they were securely in, I just put the stupid thing back.

I might try it again and see if I can pull off the glass front cover and peel back the tacho cover bit and give it a few taps (possibly punches depending on how frustrated I get with it hehe) check the wires and see if that does anything.

Are there any problems just hooking the tacho up with everything else unplugged (ie aircon, hazard, dash light dimmer, etc)?

I wouldn't think so, but possibly thought that if something wasn't plugged in, car would sense that and somehow screw up the computer.

Anyway, thanks all for the ongoing help with this one, if I figure it out, I might post a thread on what I did in detail for others to try.

Hitting the dyno today, with my stock standard R33, hopefully everything is A OK under the hood so I can start tweakin my little baby up.

Cheers all

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
