finally a cracker cold start
heres my log of a full cold start and screen shot of startup and 20sec plus.
Finally, changing to 18deg cranking timing increasing the cranking idle air right up, max -10 on the rpm flare as per Hymey instructions it burst into life like the true animal it is instead of sounding apologetic then surging like a bitch lol :) This made the biggest difference I think to the actual idle quality immediately after starting.
Also allowing idle spark trim to hit 34deg also stabilised the idle > thanks Swingtan.
My TP% was still only 20.4% even though I increased 51/52 up as high as 2.7 , I also put "1"s in the airflow multiplier up to 68deg and made no difference to TP% yet in open loop with the min air flow maxxed to 63g/s I can command the hard limit of 22% easily. So I can only achieve 860rpm even though my desired is 950-1000 at startup but its steady as a rock now! I will check again in the morning without resitting idle learn and see if it commands more
Finally a question: immediately after startup the AFR sits as 14.4:1 for 15sec every time when cold then steps down to 13.5:1. Changing IVT multiplier only causes the 13.5:1 to dip into the 12's and makes no change to the 14.4:1 section. Is there an afterstart enrichment setting somewhere or is this altered by changing cranking fuel settings?
Any ideas? I just think it would be better a bit richer as the idle doesn't truely stablise until it richens up to 13.5:1.
