Hello everyone! I’m still trying to wrap my head around this project,
it feels more like I’m getting “Wrapped around the axle” I’m reading more
about spark tables and advancing/retarding the timing according to
map-vs.rpm’s-vs.temp, etc. I found an online calculator that helps you
start initial spark tables, perhaps one of you guy’s can look this over and
see if it comes close. It’s from a site that uses “microSquirt” efi.
It ask’s specifics like:

http://www.useasydocs.com/theory/spktable.htm

Cylinder Bore: inches millimeters
Combustion Chamber Type: open chamber - little or no quench 2-valve closed chamber w/ optimized quench 3 or 4 valve engines, w/ swirl&tumble
Fuel: regular (87 octane) mid-grade (91 or 92 octane) premium (94+ octane) E85
Compression Ratio: < 9.0:1 9.1:1 to 10.0:1 10.1:1 to 11.5:1 > 11.6:1
Idle Vacuum: in·Hg
Maximum boost level:
(0 for naturally aspirated,
max. boost (psi) for turbo/supercharged)		 psi
(21 psi maximum)
Maximum RPM: RPM
Idle RPM: RPM
Spark advance table dimensions: 8×8 12×12 16×16 24×24 MS-I uses 8×8 tables;
MS-II, MicroSquirt, and the Sequencer use 12×12 tables.


if anyone has a different calculator or spreadsheets that can help us “Noobies” Please share,
I really want to understand the flow of how everything works together.
thanks again!
have a great day!
