Okay, I get the Siemens ECU is new and different and so are the O2 sensors. I understand what goes on with the maps with a warmed-up engine regarding open loop, closed loop, and various RPMs and throttle openings. What I don't understand and can't find information is what exactly goes on with the Monster 1100 during cold start and warm-up.
There are those on this forum who appear to have a great deal of knowledge regarding the new 1100's setup such as jborders5, who's looking at the ECU and its sensors now.
On a fully cold engine, what happens when you turn the key? It obviously performs some checks, but does it also begin warming the Lambda sensors?
When you press the start button, is the system open loop or closed loop? What does the ECU look at to choose how much extra fuel to dump (seeing as there's no choke)? Is there a map specifically for fully cold starts?
If it's open loop at startup, how long until it goes closed loop for idle?
Thanks in advance.
