Hey all,

My r32 gtr stock tacho doesn't work and I have just replaced the cluster with a new nismo cluster and this tacho does not work either. I am not sure if the wires on the back of the instrument cluster were connected correctly. There is a black and a green wire coming from the tacho module. I have screwed them down onto the points circled in the attached photo. Can anybody confirm this is correct? Pin out wire 7 is the tacho signal wire from the ECU is it possible to test if the ECU is sending out a signal using a multimeter? Feel free to admire my MS Paint skillz.

Thanks

After a closer inspection I realise the silver box at the back of the instrument cluster is not even for the tacho its a chim of some sort. So the only thing left to do is test the tacho signal wire. Anybody know how to test this signal? From what I have read it is a pulse signal and not voltage driven.

Thanks

    • Yeah, it was a bit of confusion with me, I rang and asked if they had a boot for a soft top, and then the paint shop when they rang and were asked if it had a hard top on it, which it does, just not a PRHT....LOL Meh, whilst frustrating for all concerned it isn't a war stopper and should be a thing of the past in a week or two In other N/A related news, car is booked in at the end of the month for the cams, springs, retainers, harmonic balancer and retune  I might even pull the lazy arse card and get them to do a full service on it whilst it is there
    • Factory LSD is supposedly a 2 way with a very conservative cam. If you've already tried adding friction modifier to the diff oil and it still locks up too much for your liking you might want to adjust the ramp rate on the cam to be more like OEM instead of reducing initial torque even further. People claim the 8 kgf-m disc kit for the OEM LSD is still very streetable but I've never been able to compare everything side by side on my own.
    • Oh man, at least it sounds they've accepted they stuffed up and not put it back on you...could see some confusion if they asked if it had a hardtop or not, and you've answered truthfully but maybe not answering their real question which is what roof did it have from the factory! Glad your keeping it N/A 2.5
    • Nah, I much prefer colour matched Talking about colour matching stuff, the new/used boot lid turned up, all painted up perfectly......aaaannnndddd, it's for a power retractable hard top, not a soft top.....LOL They are now sending a boot to fit a soft top.....,  whilst frustrating, life is like that sometimes, sometimes you just need to dodge, duck, dip, dive and, ummm, dodge.
    • You would need to paint your hardtop again though
