ASE strangeness

Postby elaw » Wed Dec 27, 2017 6:59 am

While looking at a datalog to tune cold starting, I noticed something weird about ASE. It looks to me like the ASE taper counter might start as soon as RPM is detected, rather than when the engine actually starts? So if you have a long cranking period, once the engine catches you get less ASE than expected. This image shows what I'm talking about:

Note that on the second starting attempt, in which the engine starts much faster than on the first attempt, the initial ASE value is higher, even though the CLT value has not changed.

Log (same as in the image above) and .msq are attached.
