Hi guys,

I don't drive my R33 GTR often but this morning started noticing that my car's RPM gauge (stock factory) is acting funny in the sense that it would sometimes get stuck at 5,000 RPM and then not rev over that and then come back down again and then sometimes it spins up and down a few times and resets to 0 again. 

I don't think it's a mechanical or engine issue and my car drives normally but perhaps it something to do with the gauge or the wiring itself? 

Has anyone experienced this and how did you fix it? Thought I'd check here first before taking it to a motor mechanic. 

Cheers,

Alex

I think I've read about R33's having crazy tachos, you'll have to pull the cluster out.

Did you have a wonder through the search results here?

Hi mate, 

I too heard about this - it's very weird as the car runs normally so probably just the Tacho going spastic.

Tried searching with no luck unfortunately.

Cheers,

Alex

 

Tacho runs from an ECU output.  Check appropriate pin in the ECU plug is in good order (inserted properly, not broken, dirty, etc).  Hook oscilloscope up to that pin and see if the ECU output is clean and proper.  Try again at tacho end of wiring and see if it's clean there.

Much appreciated mate. I'll give it a go soon.

Hey mate, you're a life-saver. Much appreciated.

So if I don't really care about the Rev cluster for now as I'm too busy leaving it as is won't harm or damage my GTR in anyway, would it? Seems to be a fairly complex skills fix and  requires a lot of time to take the dash apart both of which I do not have. 

Once again, many thanks.

You're welcome mate.
Taking the cluster out is not too bad, the soldering part does require some skill but it won't do any harm if you leave it as is.

You're spot on mate. I've taken the cluster out before to change blown dash globes so it's not too bad but the soldering part I'm stuck so guess will leave it as is for a while until I have time to bring it to mechanics. Once again, much appreciated mate.

There is a place in Ringwood that fixed that issue. For $120 they change and fix the cluster. They are on Maroondah hwy near the east link.

Many thanks mate. Would you know the name of this place by any chance?

Cheers

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
