I now have my VE tuning done and have Lean Cruise enabled and working. Now I am looking for some pointers on how far I can take a few of the settings.

I took the lean cruise setting from a holden tune and noticed that in the B3639 table at 0.32 grams/cylinder and 200rpms(my cruising sweet spot) the lean out was very low so I filled this cell with a rational number based on the surrounding cells. I'm hoping for some help as to how far I should be able to safely take this lean out setting on a factory engine and any pointers on adjustments to be made to get the most out of this.

Also, in B3638 the lean out rate is 0.0010. Can I make this a little faster or should I leave it alone?


Thanks!
Jesse
