WAXHEAD, i would like to know, what set-up are you using with this curve n°1.....? ( compression ratio, fuel, crancking compression,........) On my sx-r stock bore and stroke, oem carbs, factory wet pipe, 12.6 compression ratio ( 185 psi ), 1.00 mm squish, unleaded fuel pump 98 ron / 87 mon so 92.5 AKI ( i think it"s " premium in the us ) , i use a curve like your curve n°2 , 25° max at 4500rpm, 15° at 7350 rpm, rev limiter 8000rpm ( curve KOMMANDER sx-r1) on my zeeltronic PCDIS-02T ( no race , but i pratice at sea with long run at wot....).
Can you make long run at wot with this curve n°1.........? 18° at 7000rpm seems to me too much ( it depends fuel off course ).......and last question (!!!), why do you have point at 9000, 10000, 11000,.....,.....,14000 rpm ? i hope my english is understandable !!!!!!!!
