Ignition advance, Duratec startup
Posted: Mon Jun 20, 2022 8:38 am
Hi,
I've just recently started up a Duratec 2l on throttle bodies using the standard Zetec map that comes with the SW. In the standard map the advance is quite high (15-33 degrees) even at no/low load so I reduced the advance to 5degrees for 0% and 4 % load, disabled idle control, and downloaded the new map. However when I start the engine, the advance is still high ~28degrees if I remember correctly. The load is 3% and RPM ~3000 before I get the advance down, and in that range the advance is 5 degrees in the map. I can compensate with the "Adjustments degrees" in the real time mapping window and get the advance and RPM down, but any suggestions to why it is high in the first place? Is there some 3D interpolation, or startup ignition advance going on?
