Why would VATS and starter checks refuse to disable on an E38 ECM even after a Write Entire?

Here is what the documentation says. Each point links to its source; tables and names vary by computer, operating system and tuning software.

  • E38; LS2, LS3, L96; 2006-2015: On the E38, a VATS removal uses the Write-VIN/Tunerlock/VATS flash routine, which differs from other modules where a write-entire generally handles tuner-lock and VATS changes. (HP Tuners)
