just put a new nismo dash in my r33 GTR and the tacho is reading 2k rpm at idle, with the original dash it read 12500rpm, is there any adjustment or calibration I can do ?

car is running M800 motec if that helps, can the signal be adjusted in the motec ??

dash is brand new out of the box !

Just a thought but what is the real idle ? even 1250 seems somewhat high for an idle at normal running temp to me--but WTF do I know :D

:) yeah 12500rpm is pretty high :D I did mean 1250rpm, its a 2.8l with 272 cams and idles like a top fueller :) love it.........

pretty sure 1250rpm is right ...

so does anyone know how to change it, is it done at the ecu or what ?? there doesn't seem to be any adjustment on the back of the dash??

You got to open up the dash which means the plastic casing and play with the posistion on the needle really a annoying task took me a while to caliberate my gauges when I put el glow lights

Don't move the needle :blink:

Have you got the Motec software? If so you can check on the ecu what it's reading and see if it's reading the same as the dash (give or take). Pretty sure you can adjust the pulse width of the tacho signal to suit but don't quote me on that.

Idle speed sounds about right at 1100 - 1200 and the tacho won't be able to keep up with the revs anyway, mine doesn't.

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
