Since I had some difficulties starting the Duc , I logged some starts with the oem ECU .
I also logged quite a few "virtual" starts spinning the toothed wheel with a hand drill , varying TPS , Toil and Vbat aiming to find out how WM treats them .
Sample rate is only about 4Hz , so I did 200 -300 spins .
So far it seems that ...

IgnAdv is temperature related , at least until 1200-1300 rpm , in two steps . First , ending at 300 rpm -> 1 deg , and the second ending at 700 rpm -> 27 deg@0C to 3 deg@105C .
Priming is over by 30C , above this using values from the map .
It might be that priming (till 500 rpm) is also related to TPS .

My grasp of stats is not at all good , so the above observations might be only in my mind .
Anyway , if someone is interested to play , let me know how to attach the folder containing both .txt and .stf (openable with AEMlog) files .
