What does that EFI system need for vacuum signal? Any? I'm no fuelie guy. Your cam and intake don't seem like they're conducive for making much vacuum at idle.
Makes 15" at 700 rpm. Base timing is 12*, idle timing is 17*, 36* by 3000, cruise advance is +8, or up to 44* at cruise. At 2000 it's showing 25-26 degrees. WOT fuel is 12.8. afr. This is the turd in question.
