As I said, the cold start is hard coded and you can t tune it out


you can tame it down, as yours is right now


During cold start injection is stratified with early Port injection at 50%, and the other 50% is late injected by direct injection basically directly into exhaust


Tameing it down as you did just reduce the bark, and produce more torque into the crankshaft and less heat is diverted into exhaust


nonetheless, just do what you like, not so important anyway, I keep normally -3 of advance timing during cold start, and rpm under 1200
