I don't believe that lean cruise is implemented in $0D, but I could be wrong. I would like it to be, and it's on my list of things to attempt. I intend to try adding the code to do so. (that only happens in the winter time when I can't do stuff outside.)

However, I'm wondering if you could make note of what blocks you're in during normal cruise. Then, add a little time and adjust the VEs to a little lean? Would that even work?
You can - sort of.
I can't really find much information on how this actually works though, I've tried it and I can see my desired AFR changing but as I don't have a WBO2, I don't know how accurate it is. It doesn't seem to run in actual open loop as I still see the NBO2 switching like normal, but BLM's don't change, I assume it uses the VE tables for 14.7 and guesstimates how long to stay above/below the stoich point on the NB to reach the desired AFR.Quote:
Title: Open Loop AFR vs. Temperature vs. Vacuum
Location: 4BB4
Usage: Open Loop AFR Tables
Tips: Normally used for open loop but can be used in closed loop if L400D Bit 0 "Open Loop AFR Enabled" is enabled and temperature is greater than L48C6 "Minimum Temperature for Closed Loop" and temperature is less than L48C7 "Maximum Temperature for AFR Lookup in Closed Loop".
Hopefully someone else here has played with this and has some more info as it seems like a good solution for those of us who don't have to stay at 14.7 because of cats.
