Lean Cruise COS3 LS1B

[ttls1]

Hi I have a 2003 Silverado 1mb PCM with COS3 03150003. I found the lean cruise CAX that is based on the original OS 12579405 and renamed it 03150003. I then saved it in the EFILive\V7.5\Calibrations folder. Now when I open the tune file I get an error "[B9000]'s address $02AAB8 is outside the calibration address boundaries" Am I doing something wrong? I have updated both computer and V2 to the latest versions and I also get the same fault on an older computer running an earlier version.

Cheers.

Just thought I would also add that I get the same error even if I use the original CAX file with an original Silverado tune from tune file depot.

Ok I have got it to work. I had to go into Edit / properties / Options and tick the "allow CAX files to modify operating system memory for some controllers"
