    Default 0 Degrees when Cranking?

    I am trying to log timing when cranking, but am not having any luck. EST_Crank_DMA does not show any data when logging. I am having a hard start issue and have tried adjusting B5909, but no luck. Has anyone seen an issue like this?

    Seems like I am reading 0 degrees when cranking when using a timing light.
