As promised, 2.0 OHC main spark to 12 psi

These are from a 3 BAR calibration. 2 BAR tunes will need will need to add values below 45 kPa and will need to add timing between and above the MAP values in this list.

There's also a table which modifies spark advance under boost based on IAT. Like above, MAP is horizontal. IAT is vertical.


0 25 50 75 100
0 0 -1.1 -2.5 -3.2 -3.9
23.5 0 -1.1 -2.5 -3.2 -3.9
49.3 0 -1.1 -2.5 -3.5 -4.2
80 0 -1.1 -2.5 -3.5 -4.2
105 0 -1.1 -2.5 -3.5 -4.2


This is for an intercooled engine, 95% stock, with 5spd manual trans.
