I’ve added 10 degrees to the table at and greater than 16.0:1 and have my lean cruise to lean out at 16.5 but I’m not seeing any advance on my logs. Timing stays pretty close to the octane tables.

Silly question, do you have a way to log to make sure you are indeed in lean cruise? Post or pm a copy of your tune and I'll be glad to take a look at it and make sure it's not something that I messed up on.

Here is my tune and log. Thanks for taking a look!

I think I've figured out where the timing went. There is a multiplier based on MAP that was set from stock at 0.00 up to 50 kPa and would not really make a big different till the MAP values began to be over 75-80 kPa, a place where Lean Cruise would probably not work. I edited and posted an new XDF in the first post that now changes all the values in the table to 1.00 so that should fix the timing issue. The table is called "EQ Spark Advance Multiplier Vs. MAP". I'm attaching a copy of your bin with this change already made. Let me know if it solves the issue!

Thanks! That fixed the issue!
