New Nismo Dash

[tricstar]

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

[NA_Goodness]

12,500rpm is pretty damn high for an idle

Even 1250 seems high, but it has been tuned. Is there something you can plug into the ECU to read it off that?

[tricstar]

yeah 12500rpm is pretty high 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??

[omy-33]

should sit around the 600-800 mark im pretty sure at an idle.

^No.

800-1000 stock.

That is in no way stock.

[NA_Goodness]

Yeah, stock is ~800rpm. If its got a new ECU, your tuner will be able to lower that for you. You'd have to go inside I'd say. Unless there's an idle-control screw on your throttle body?

[NYTSKY]

Id say the idle was lifted to give a bit more vacuum at idle with those big cams. Otherwise it would stall.

thanks NYTSKY, yeah,I'm not wanting to change the idle, just calibate the tacho ??

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

really, thats the fix ? open it up and move the needle

[jonn]

Don't move the needle

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.
