Is it possible to enable warm up enrichment for idle only? I attached log and tune.
In the log, wideband controller kicks in at 61s and the cold idle AFR is around 16. It's bad. Here's what I've tried so far:
Increase WUE - this helps with cold idle but I end up with ridiculous AFR like around 11s at cold WOT.
Increase VE around idle. It's 30 now and even this is too high. Look at 1117s in the log. Despite gamma is already at 96 due to IAT density correction, AFR is around 13.5. This is already too high as I'd want 14.7 there. So I should actually lower idle VE to about 26. But if I do that my cold idle would be 17 AFR...
How do I deal with this?
