I'm trying to make sure I fully understand everything there is about VATS deletes, so bear with me and please help only if you are 110% sure you know the answers. This one's probably best left to the pros, just to avoid any misinformation.
Do I ONLY need to do a Write Entire when the VATS deletes are VATS patches?
Can I or should I ever do a Write VIN/Tunerlock/VATS when deleting VATS?
Is it true that I have to Write Entire when VATS is under the OS tab, and I don't have to when VATS is under the System tab?
Do I have to turn off every theft and immobilizer code to delete VATS, on all models?
Do I have to disable Starter Fault checks?
Do I have to disable Starter Diag checks?
Do I have to disable Clutch Disable checks?
Why would I have to disable any starter or clutch checks in order to delete VATS?
Are there any unusually hard or impossible to delete VATS situations or PCMs?
Thanks for your insight, guys. I appreciate your taking the time.
