Mathys Posted April 21, 2008 Share Posted April 21, 2008 I have a MY03 and my idle never exceeds 1300 rpm, even on a cold day. However, a friend of mine has the 2007 model and his idle on a cold day (1 degree celsius) is around 2100 for a minute and then comes down. Is this normal for the new model to have the increased idle rpm? Quote Link to comment Share on other sites More sharing options...

Is this normal for the new model to have the increased idle rpm? Yep, mine does it and I've heard of others too. It only revs that high for say 10 secs before falling back though - not a minute.

Beavis Posted April 21, 2008 Share Posted April 21, 2008 I would say 2100 is far to high, i know they are initially high when cold but i think that is excessive. Quote Link to comment Share on other sites More sharing options...
Ebized Posted April 21, 2008 Share Posted April 21, 2008 I guess this down to the ECU - once the various sensors kick in everything then levels out - rather like some who experience extra power when driving off from cold - until the air/petrol mixture gets told the right ratio?

Digsy Posted April 21, 2008 Share Posted April 21, 2008 GC350z has confirmed his does it too. Its a MY07 thing. Quote Link to comment Share on other sites More sharing options...
GIXXERUK Posted April 21, 2008 Share Posted April 21, 2008 GC350z has confirmed his does it too. Its a MY07 thing. must be an open loop thing , maybe its to do with the dual intakes ? more air/ more petrol til the ecu picks up the sensors Quote Link to comment Share on other sites More sharing options...

Its a MY07 thing. must be an open loop thing , maybe its to do with the dual intakes ? more air/ more petrol til the ecu picks up the sensors +1 - that's along the lines of what I was saying and the therefore the extra (cold) airflow puts the revs up that bit more Quote Link to comment Share on other sites More sharing options...

GC350z Posted April 23, 2008 Share Posted April 23, 2008 GC350z has confirmed his does it too. Its a MY07 thing. Yep perfectly normal. Nice and loud startup too Quote Link to comment Share on other sites More sharing options...
ZeddZ Posted April 23, 2008 Share Posted April 23, 2008 Mine does it as well.Nearly posted a thread myself because I thought it was to high. Quote Link to comment Share on other sites More sharing options...
KS2006 Posted April 24, 2008 Share Posted April 24, 2008 At cold start mine ildes at around 1700 rpm. Within a minute or so its down to 1k and then within a couple more 750-800. I tend to wait for it to settle before setting off - in a tight car park tickover at those revs is quick enough People always look at you funny starting it cold in car parks - like a Z needs more attention Quote Link to comment Share on other sites More sharing options...
garry Posted April 24, 2008 Share Posted April 24, 2008 Mine does it too... It's great fun the way it hauls you out of the garage in the morning at 2k revs and you're cacking your pants in case you reversed in squinty the night before and are going to scrape a wheel arch Quote Link to comment Share on other sites More sharing options...
GC350z Posted April 24, 2008 Share Posted April 24, 2008 I do enjoy it. It seems to drive on pure torque for the first 30 seconds. I start it up. Pull out of my space. Then take my foot of the clutch and gas and let her drive herself up the hill out of the undergroud. On startup it revs to 1900 for a few seconds then drops to 1750. Sits for a short time before making its way down to about 800. Quote Link to comment Share on other sites More sharing options...
