EFI Live E38 VATS patch?

[dave w]

I'm working on a 2012 5.3 liter E38 computer. I've not worked on a vehicle this new. I'm wondering if anyone could share a link / information on how to apply the EFI Live VATS patch. Attached is the .tun file I've read from the E38 computer.

Thanks,

You shouldn't need to change anything on the screen shot you posted. Plug in your V2 to your computer before you open the tune. When you open the tune, click on the "Engine Operation" folder, you will now see a RED folder at the very bottom called "Operating System Patches". Open this folder and you should see parameter B9903, "Disable VATS Patch". Select "Applied" to apply this patch.

Also, go to parameter G1220 "Starter Relay Type" and select "Not Used".

Save the tune and exit the program. It requires a Full Flash to apply the VATS changes to the E38.
