Hi guys, can someone tell me if there is a known indicator of fuel quality in terms of octanes, that can be visible in the comparison of data logs?

For example, if I use 87 fuel then a certain sensor or calculated value in the data log would be higher or lower than if I used 97 fuel. Or maybe the average value of some sensor?

Something like the ST fuel trim that tells me if I am running rich or poor.

All considering the same calibration and similar climate conditions.

The knock control gives you an idea of the quality of the fuel.

Thanks for the reply. I will check my logs.
