gen5 e92 ECU VATA Algorithm table

[modularfox]

under System/General tabs, Vehicle-> VATS Algorithm (ECM 731) has 3 options

Opel
PPEI3
NAO

when disabling vats, whats the difference.

In the past swaps, I would disabe VATs 1 (only option available on the stock tune file) and disabled Starter Diag and still would not run, always flashed a 2014 tune that had vats 1 and 2.

I read on another post where someone recommended NAO vs stock Opel .... I cannot seem to find any info on what the difference is between them and why you choose one over the other.

Thanks
