Lean Cruise - US - LQ4 6.0L - Anyone done it?

[Zfreak]

Are we able to enable lean cruise on our vehicles in the US? I know it's not "legal" due to emissions...but as far as reality...can it be done? Looking to get the 14mpg on my LQ4 up a bit and lean cruise sounds like a promising option.

Not by enabling it in the config. There are several internal routines that take place to ensure the vehicle is not a US vehicle.

Use a custom OS and lean out part throttle in B3647 is your next best bet. Or mess with O2 switchpoints perhaps.
