Lean Cruise is enabled but doesn't operate

I used to have LC working on my 12212156 stock 5.7 vortec tune, but I've noticed that since I have done the 24x conversion and now run a 5.3-base tune my LC doesn't work anymore. I was really interested in getting that dialed in after I did the 24x. I am still running the ...156 OS.

I think I have the latest .cax file and I see the option of enable/disable in my tune, have done a full flash, and still won't get any change in the commanded AFR value.

My PC where I build my tunes always has the errors "B9000, B9003, B9006, B9007, B9011, B9012 overlaps pre-defined data..." so I click OK and everything looks fine. My laptop from which I flash to my PCM never gives me these errors and it has the same .cax file.


Any thoughts on what I'm missing?

Open the V7.5 Tune Tool ... click on the "Edit" menu ... in the drop down click on "Properties" ... when the smaller pop-up screen appears click on the "Options" tab ... then check the box that reads "Allow *.cax files to modify operating system memory for some controllers."

Whenever you open a tune, and you get the "overlapping" parameter message - it means that the parameter(s) will not be allowed to load.

That is already checked on my laptop which I flash from. I make the tunes on my pc and send them to laptop. Are they corrupted because pc won't load right tables?

B9000 is not found on my laptop. But don't get the error on it either.

Did you copy the respective *.cax file to both of your computers ? ... could perhaps merely be missing ...

Just ran inside to check PC. It has the B9000 errors BUT it has the 'Allow .cax files to modify....' already checked.

my 12212156 .cax file on PC has B9000 when I search but laptop doesn't have it.

Is there a recent LC .cax file somewhere?

I think I need to get the latest file. Mine are completely different between both computers
