Timing UNK Tables

Does anyone know what exactly these tables are for? And what conditions can trigger them? @MOTIV Motorsport @Josh@Cobb

ATR has 7 of them:

1. Timing (Unk Base Throttled Safe)
2. Timing (Unk Emergency Limp)
3. Timing (Unk Optimal Throttled Safe)
4. Timing (Unk Optimal Throttled)
5. Timing (Unk Optimal VVT Safe)
6. Timing (Unk Optimal VVT)
7. Timing (Unk Throttled)

Table 1 is all 0'd and has worthless axis, 3 & 5 are the same, 4 & 6 are the same.

Additionally, what triggers usage the Timing Fail Safe and Timing Open Loop tables?
