This morning on my way to work the needle flick to the other side after I reved the rpm at around 4k or 5k, and it stays there, how weird.

I searched some pictures to show you what does it look like now。

can anyone tell me why it happened, what will this do to my car and what should I do now.

Thanks heaps.

Picture 1: This is how it is now

Take the plastic face off and turn the needle counter clockwise back to zero.

Sometimes if the needle revs up quickly enough, or far enough past redline, it can't make it back to zero since gravity is giving the needle a hard time going back up, and holds it down on the opposite side.

If its resisting, DO NOT push it otherwise it will be out of sync (which is a pain in the ass to re-sync). It should rest on that pin just below 0, and with the ignition ON it should hold at 0 by itself.

Thanks mate for the advise and help! I'll do it tomorrow and will keep you updated

Just another question: Is this a normal thing to R33/skyline/any other cars?

Dunno what you mean by normal...

Its not common but its not exactly Christmas when it does.

sorry mate my English is not good.

What i was trying to ask is that has such thing happend on other cars? or like is it a common thing to happen on a 96 sports car?

Coz I'm abit worry that this will cause problem to the rpm sensor or related component and hence cause damage to the car。

Ah righto.

Its just as likely to happen on any car with a tacho.

Don't worry about damage, there's nothing wrong, this just sometimes occurs when the tacho climbs quickly and goes too far up...it can't cause damage in any way.

Thanks heaps mate, much appreciated.

By the way Cefiro was in my list when I was looking to buy a rear wheel drive car in NZ, but after coming to Australia it became almost impossible as there were not many around, but now I still love it, for it's shape and the fun driving it.

    • Still fast enough to have fun (kinda). Time for a modern turbo with a divided turbine housing and a proper twin scroll manifold. I think 400-450kW is a great place to be, provided it's all in before 4500 rpm.
    • i'm not at 600 though 😢 its 484hp (356kw) at the wheels.. 
    • Nice. 600ish HP is probably a nice place to be.
    • In the US the EPA has been going after shops that sold aftermarket ECU tuning software that allowed you to disable CELs for things like EGR, DPF, SCR, or TWC failure. They also went after shops for selling emissions delete equipment. Their logic is that all cars built for street use have this emissions equipment and you cannot do an after the fact conversion to an off-road vehicle not intended for street use. Cobb, Hondata, and similar companies have basically all revised their tuning software such that going forward you cannot suppress DTCs for emissions-critical systems, nor can you toggle systems on and off in the tune like EGR. You also cannot adjust OBD emissions monitoring logic. You can still tune these cars. But you have to do things the hard way, basically. For example Subaru FA20DITs used to delete the TGV system to get spare analog IO for a flex fuel sensor. EGR also has to be dramatically pared back because without the TGVs the stock EGR map causes bad misfires. Now instead they have to implement the flex fuel system as a CAN bus sensor instead. IMO, this is heavy-handed but the EPA in the US gave so much leeway for so long and the aftermarket relentlessly abused that leeway to the point that they could actually see the effects of all these emissions-deleted work trucks on their air quality monitoring for cities that haven't met Clean Air Act standards. It's one thing to have a few people deleting emissions on their weekend car that spends 9 months out of the year on jack stands. It's another thing entirely for entire fleets of tradies driving around 8 hours a day on deleted diesels that emit 1000x the emissions per mile of a compliant vehicle.
    • Hmmm. that's a tough one. There's a lot of history bundled up in that lot. Perhaps instead we can create a new pinned thread, called "Legacy Pinned Threads" and provide links to the these ones that will be unpinned in there. And maybe put the names of the pinned threads that are linked inside in the tags so they can seen from the outside? Or something like? I mean, it's half a step back towards having a more complicated forum structure, without actually having it. But there's a reason that heirarchical architectures exist. They are logical, and if executed properly, make it easy to find something without having any upfront knowledge of where it would be , and without using a search function.
