Hi guys,
I'm building a 65 Daytona Kit car with a 2003 terminator running off Megasquirt 3. I have the stock borderline knock and MBT tables for reference but they don't directly translate to the megasquirt tables and am looking for advice on the table below.
Its a stock motor with the head cooling mod, larger aluminum heat exchanger, and a good aluminum radiator.
I'm looking for 93 octane timing advice on about where these engines idle, 100kpa Spark, and 5, 10 and 15 lbs boost spark.
Looking for safe spark settings to start with. Any advice welcome especially from any professional tuners out there.
Here's the table I have worked up so far, the red 5, 10, and 15 are in PSI of boost rows.

table looks decent, those two 28 degree cells at 600, me personally id change all 6 of those cells from 600-820 30-45 to all 22 degrees

at 600 and 820 when you get into boost your adding a little timing, it wont matter any but i take it you didnt mean to do that

the bottom cells can all come up, starting at 1000 and working over id kick them up to

31,33,35,37,39,41 at 3k on to the end

usually at a 2000 rpm steady highway cruise i shoot for about 34 degrees

at 100 from 3k+ you can take her on up to mbt at 27 degrees, 5lbs idrop it to 23, 10lbs 21, 5lbs 19, basically +2 degrees from where your at

you can extrapolate in between, i usually work in 20s, 30, 50, 70, 90 kpa and interpolate in between

Thanks decipha,
I made a completely new table based off fords and your suggestions. The 2 cells at 40 and 45 are to kick the rpms back up if it tries to stall (turn on a/c etc), once I get the closed loop idle straight i can remove them.
I really don't know how much Hg vac it pulls at idle, if anyone has a vac guage with #'s that would help to get the chart scope set better (kPa Y-axis), anyhow i lowered it to 20kpa.
I tried to smooth in the 34 deg at 2000 cruise (69mph), and smooth the transition at 3k at boost levels.
I'm used to tuning pushrod sbf with turbos, so this is new to me, the 4v requires so much less timing everywhere that it make the table look odd to me.
Any more suggestions on the new one?

looks good, i would take 4000+ and clip it to no more than 43 degrees, you wont see any benefit going any higher than that

Thanks decipha, I will change that.
Heres my AFR, its a little rich to leave room for tuning so I dont hurt anything.
See anything way off or suggestions for final AFR in the 5, 10 and 15 lb range for a stock terminator?

its safer to be too lean down low rather than too rich, i would take everything from 80 and below and set it all to 14.7

set all 90 and 100 to 12.8

135 on up to all 11.8
