No and never will be, use a COS and set it up to enable pseudo lean cruise.

Interesting to know...personally Ive never tested any LS1 based stuff as I dont have access to one. All the LS1 testing Ive done has been in fooling my P10 to think its an LS1 in EFILive for scanning purposes.

I have lean cruise available to me and I don't bother using it. If you use OS3 or OS5 just use B3647 to command what ever AFR you want.

how did it go

I am not sure i don't have a wideband on this truck yet. although i did try it and could smell like hot cats lol, so one would have to assume it worked? not sure?? maybe you can tell from the o2 voltage?? here is a run it does have some spark knock though. I supposed once you would lean a vehicle out in these load ranges it would possibly cause spark knock from a lean condition????

your commanded afr will change to what you are commanding. If it stays at 14.63 lean cruise is not activated.
