First off, once up to temp, my system runs flawlessly.
On cold start, no real issues other than the initial first drop (2-3 seconds) after turning over will cause the system to go lean just for a second, but it will catch itself and go back to a richer state as it warms up, eventually reaching target AFR.
If I go out for a drive with the engine cold, releasing throttle will usually cause things to go back to a momentary lean state as it returns to idle, then the system will catch itself and go back to normal AFRs. As it continues to warm, this gets to be less and less of an occurrence. Once up to moderate temp (+140 or so) no real issues. Over 160 all issues are gone.
Have any of you fine tuned the Sniper system to run better when cold? From reading things out there, it seems most of this can be tuned via the Coolant Enrichment Table. I have never tuned an EFI system via software. Just some basic tuning on the 3.5" LCD screen.
I guess maybe the easiest answer is to go out and grab a couple data logs and send them over to Holley? But I would like to learn what is happening and how to correct it at the same time.
Any thoughts?
