Idle speed up - ecu - problem after heating up to 85 c

Postby Libi » Wed Mar 11, 2015 9:34 am

Hi,
Fiat stilo edc15c7 2004r 115 CV.
I found idle map, 6x1 and up make 100rpm up.
Download to car, start engine (cold) about 5 degree C.
It start warming and idle speed was consistent with map, from about 20 degree was 950rpm ( orginal 850)
Now engine is warming to 85 degree C,is ok rpm 950, and temperature drop down, when temperature is 83 degree, rpm are drop down to 850.
You can put gas, increase rpm, but idle speed is 850.
When you shut down engine, and start immediately idle is ok, until engine temperature will drop down 83 degree C.

Any idea was is going on ?
Injection has 2mg correction on idle speed and warm engine ( min 4,94mg -max 6,83mg - log time 2min)

Also, I asked this question here:

But nobody reply, so maybe we try here.
Where the idle RPMs are stored in EDC15c7 map?
