Try this :)
EDIT:
Sorry guys, we can't have these patches on our forum, try the torrent sites or pass them around via PM or Email.
Has anyone tried this to see if it actually works? I want to, but my truck is COS3 and I broke the steering on my dads truck, so I haven't had a chance.
Thought you were gong to try it first . :gossip:
I run a COS3 as well , since you said it would not work with it I didn't try . :badidea:
Haha, I would if I could find a test vehicle around here I could put my WB in to verify it, but for whatever reason, the B9000 enable button doesn't appear in the COS's :( or I would test it on my truck since I have a permanit WB installed on it and the other tables are there.
The Lean cruise routines won't work on a custom OS because the custom OS's run in open loop mode, Lean cruise is only activated once the PCM is in closed loop.
The whole idea behind the AFR table in the custom OS was to be able to create a pseudo Lean Cruise mode anyway.

Rich mixtures cause incomplete combustion, the residual unburnt fuel helps keep things cool and "safe," though obviously not good for economy and emissions.
Factory tunes for example run some PE tables in the mid 11:1 ratios for cooling purposes (cat protection, exhaust valve).
A lot of the Holden tunes (holdencrazy.com) have factory validated lean cruise parameters in them. If you want to play safe, download a few of the Holden Commodore tunes and copy the same parameters.
Though a read of this might be helpful.

I've seen quite a few engines with piston damage due to weak mixtures and considering no HSV or Corvette tune uses lean cruise, it's for a good reason and they (GM) have an awful lot more money to experiment with this kind of thing than I do. Though having no lean cruise is clearly for performance applications.
As mentioned in the above link, a couple of extra gallons of fuel used is cheaper than a new engine.
Whereas for daily drivers that aren't tuned for all out performance and enjoy cooler climates than the desert regions, the parameters in the Holden tunes mentioned would be a help.
p.s. Unsure why ppl say there's no closed-loop operation in the Custom OS tunes?
OS3 (SD) here with CL operation.
You do realize that , Ross is a owner of EFILive and programmer for it ? COS3 has a "Semi Closed Loop" mode which if values are set to stoich it will use O2 sensors for fueling , but you still have full control over AFR mapping .
When in COS3 , I understand that the some tables have been moved to another part of the EPROM memory , does the Algorithm still look for those tables and if not found , look for alternate tables , ones that were added ?
