I need help asap please... Idle vs temperature problem AEM EMS !
So .... I just change my IACV ( behind the IM ) on my D16Z6 cuz he wasnt good anymore... and the problem still there :
My car stalls when hes warm at a stop sign or when I brake suddently...
and when the engine is hot the car starts and after 1 second or 3 he just stall I have to give a lot of gas to keep it running.....
So my tuner said to try to play with the Idle vs temperature graph... so I tried to raise my idle but nothing happen ??? WTF ??
Is it a wiring problem ??
oh and my VSS doesnt work too ...
So I was supposed to meet my tuner tonight to get a racing fuel map but it seems that I couldnt be there... he told me to fix this problem... he dont want to search...

Does it stall when you press on the gas slightly or when your trying to idle..
Also a side question not related to your problem, What internals do you have in your z6 motor..

I dont know to what my idle is set.... it run always at 1000 rpm cold or hot....
The car stalls only when I let my feet off the throttle pedal ...like on a stop.
Or when I try to start it without giving gas when hes hot...he starts...and stall after 2 seconds...
see my sign for detail on my car ( the link for the dyno all is there )

No, I am talking the Idle feedback settings in the software.
Like the TPS on and Off, RPM level, etc.

Re: (yellowturbo)
How warm has it been near you ???
I skimmed thru this post but remember that as temps rise you will need to lower the fuel that is sent into the system. If you tuned the car to idle when the outside temps were 40 degrees or so then you will be too rich now when the temps are higher without some compensation.
There is an intake air temperature chart that you might want to try adjusting if you think I am thinking correctly. I found this out the hard way recently with my car stalling constantly but she idles like butter now on 580cc injectors at 750 RPM.
PM me if you want some other ideas.
