WayneC can you comment at this? hasenpfeffer this looks like a typcal example of the idle actuator losing its memory/way. I have had a very similar issue with and ECU that had the adaption values reset and yes mine did idle for 20 odd seconds and then stop early on after the reset...and on the first few rides on cold and warm cold starts it stopped a couple of times and idled high then settled, however it has now settled right down and not put a foot wrong on recent rides. I'm thinking if you ride it some more and have some more starts and stops it might rebuild the adaption tables and come good as mine seems to have done. Fingers crossed for you!
