I have a 1996 r33 series 2.

Until today it has driven no probs.

Tonight whilst driving the factory tacho in the cluster started to jump around. At a constand 100k's on the freeway i the tacho would show anywhere from 3000 to 9000 rpm. The actual engine revs did not change.

Car has

Stock ecu, injectors etc

Boost controller

3.5" exhaust

r34 gtt smic

so it is a mild car. All mods have been on for a while and no work has been done lately on the car to cause this.

So, any idea's?

Any help would be appreciated.

Thanks

Usually an ignition fault will cause that, however you would have felt the car run shite, if that was the case.

You will have to put a scope onto the tacho output terminal on the ecu and check its output is o.k. If its o.k. it more then likely guage cluster itself. Check the guage ground wires first however. Could be a cracked track on the board, hard to say without looking at it.

Only thoughts I have, others might know more...

sounds weird. Maybe just try resetting the ecu. Un plug the batt terminal and let the car sit for a while, then atatch the the terminal again. I can't garantee that doing this will fix the problem, but it's something to try before taking the cluster out.

min has been having similar issues.

mine just kinda freezes.

like i'm accelerating to 100 but the speedometer stops at 60 and then after a few seconds it just jumps to 100

and while that's happeneing the KM's stop counting as well. The tachometer keeps working as usual however.

Hey dude,

I had very similar problem. (If you have done a search you most likely would have found my thread). The problem for me was within the tacho mechnanism its self, nothing to do with the signal from the ecu. I took the easy way and put a new cluster in, but there are many guage servicing companies out there. Have a look in the yellow pages.

Cheers

hey,

mine does a similiar thing, try hitting the top of the dash, solves it 90% of the time, mechanic said its a screw that becomes loose if your dash has ever been taken out and not put back in poroperly.

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      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.
