Here's a startup sequence on the Volt while monitoring all 3 phases of MGA and the ICE CKP during a startup command due to the hood latch opening. Gen 1 Volt 1.4 LUU 4 cyl.

I really like this and being able to download the file right from the post is great. This is very interesting test that was being performed as well.

Thanks Michael, I felt it was worth noting the ICE start up sequence as driven by MGA. I have some other traces here that show the CKP vs. CMP's vs. Coil and Injector current as well.
