Read a book today and learned something, maybe.
My thought:
Why do some ign maps have 1 or 2 rows between start & idle, like 2 between 600 & 1100RPM?
Book said if/when idle is weak/dropping, if the row below ideal idle RPM has higher ign than idle row, it helps keeping idle steady
if manifold pressure or if A/F is weak at idle etc, acc to book.
True or false?
EDIT: Tried 217 Ign Adv at top 4 TPS & from 5500RPM, throttle response seems killer when I just started.
Cheers, mates, a little drunk on my birthday.
