With this in mind, the stock holden Lean Cruise, doesn't activate until you are over 47mph. You may want to lower that speed.

[ LC_Vehicle_Speed_Hyst_High*01- ] is what it is called in universal patcher.
Some report they can feel it and makes the vehicle a dog when activated too low. If I remember correctly, that is mostly in trucks though, I don't think you would have that issue, but you may want to experiment.
If you get a wide band, you can play with the lean cruise ratios and see what your car likes, I wouldn't until you get one though.
