Idle vs Main (Hi Octane) Spark Tables

It is said the GM ECU uses thresholds to bounce between the Base Idle and Main (Hi Octane?) spark tables based on a set of thresholds which I believe to be the following:

1. TPS or MPH > threshold = use Main Hi Octane Table

2. TPS and MPH < threshold = use base idle table

TPS < threshold and speed > threshold = use main Hi Octane Table

Does anyone know where these threshold tables are located on the GM E67 table sets?

not super familiar with this ECU but i don't think these threshold tables are adjustable in HP tuner software,

Understood. Not trying to adjust them, just trying to find them to see what the thresholds are.
