Al is right, the EC2 adjusts the amount of ignition time
retard based on your initial static timing setting and the rpm and can be
further adjusted by whatever adjustment you may have made in mode 7 of the
EC2. I don 't know what relationship between rpm and timing or the
algorithm Tracy uses, but I would assume it provides more advance ( really less
retard) the higher the rpm - but just a guess on my part.

Subject: [FlyRotary] Re: More MAP
measurement questions
Excuse my ignorance here, I have
absolutely no knowledge about how ECU's work. I've heard people say that it
reads MAP settings - so what is a MAP, and if it's different because the
pressure is different at different places in the inlet, how can the computer
calculate the inlet charge and timing.
It is my
understanding that the EC2 does not adjust timing but the injectors pulse
width only. Is this correct?

It also adjusts
the ignition timing. I don’t know what the formula is, but I’m sure
it uses RPM.
