Pulling my hair out

Do you have a data logger?
A video of the voltmeter may tell the story if it is a battery/ground issue.

I do not. I’ll have to try it again, and watch the volt meter when I launch. Unfortunately there isn’t another race for a couple weeks, and it’s 250 mile away. Don’t think I want to drag my car all the way there just to fight it all weekend.
