Hello to all.
I have a problem with VW Bora 2002 1.6MPI with ECU Siemens Simos 3.3 (inside C167 and 29f400). Car don`t have a normal cold start rpm. This ECU has 2 temperature sensors and they works ok, but after starting car do not up rpm above 800 (if coolant temperature not above 5-30 C). After warming of engine iddle speed rpm is in normal values (850-870rpm). I have tested ECU on the bench and not detected hardware problems. Anyone can increase cold start RPM in firmware (need set to 1300-1400 RPM)?
