Dude, so sorry to hear that. Glad you figured out your hot start issue, though.

when you changed the fueling and corrected the hot start,did that change the -64*? im having issues with multiple misfires at startup and kickback on hot startups. i also get a -64* just switching the ignition on.
By the prickle of my thumb something wicked this way comes!2008 Chrysler 300c! 2013 heads/220/230 comp cam/LTheaders/FTI 2600 stall converter.
I feel this is just fine. Negative spark just lets the engine take control of itself and control an idle after a start. Maybe catalyst heating. But you also said hot which I am seeing too. It should as I see in the log go positive after a period of time and continue on. I want to say its idle control related or a startup sequence relation. I've never found a need to chase this one behavior. I see it in nearly all these cars and trucks, of even GM flavors too. "Go negative and find stabilization, then go positive." Just making us all think. Someone will point a hard finger on the table we can mess with one day.
