My Tacho is screwed....

[BOOMAU]

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.

Maby you can wait til this guy a work i know does it to his... Save your self some money...

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

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

[Col-GTSX]

The RSM doesnt help in fixing the factory gadge tho... thats a cover up fix.

But even then its not road worthy with no speedo.... RSM does not count as a speedo...

[Col-GTSX]

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....

[Birnie]

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

Hehe

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.

[Birnie]

Plus you can set it up as dials too (digital ones), not just numbers

[Col-GTSX]

The needle output has 2 dials less than an inch big.... Common...... (hewitt style)

I had an AVC-R and SAFC... Anyways lets get back to the topic on hand....

[Mr GTS4]

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.

[Col-GTSX]

So you believe it was in the actually gauge....

The fault i mean...

[BOOMAU]

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

Take it to an auto elec. Save yourself the grief
