[Diy_efi] 93 pontiac grand prix... I think the 3.1L auto

Sat Aug 12 14:42:49 UTC 2006

Oh yeah, we're still friends -- i'm sure he's laughing as he reads this

He put some data in the 6k rpm map, then zero'd it out not knowing it upped
the redline.  i didn't know either -- so i guess not knowing is just as
dangerous as stupidity.
