My Lean Cruise Questions

[RevGTO]

Rather than hijack the other thread, I thought I'd start a fresh one ...

I'm working on LC enabled tune after downloading the .cax file (thanks, guys!!). I've set up the parameters following what "Whipple 496" did:

B9100 = Enabled
B3634 = 120 seconds
B3635 = 20 seconds
B3636 = 45 mph
B3637 = 30 mph
B3638 = 1.0

Then I downloaded a stock 2004 Monaro tune and pasted in its values into the B3639 LC Target AFR table.

Questions:
The stock B3638 lean out rate is .010. Is the 1.0 above ok, or too aggressive?
Are the stock B3639 LC Target AFR values good, or should they be modified?
If the latter, does anyone have a table I can reference?

Comments are appreciated - thanks!

B3638 should be 0.0010

The 04 Monaro B3639 will be a good start, the same table in a 01-02 Holden is a little more aggresive and maybe better if chasing fuel economy. And you can massage the table yourself a little extending it's working range up and down in the map range a cell or so, little bit of trial and error to get it working at your normal light cruise speed.

Also table B3646 must be populated for it to work and you can populate a cell or two lower in the temp range with 0.50 to allow lean cruise to start working earlier during warm up.

Also you can play around with lowering B3636 and B3647 to have it activate at lower speed.
