Help with translating/converting hall sensor values from BLDC to FOC

Hi guys,
Does anyone know how to translate hall sensor values from BLDC to FOC?
For example, my current hall sensor values under BLDC is: -1, -1, -1, -1, 1, 3, 6, 4 and I want to input this value into the hall sensor table under FOC mode in such a way that it would understand. Based off of some research, I know that a -1 or 0 value in BLDC is equivalent to 255 in FOC. But what about for other values like 3, 6, 4, etc?? Is there a conversion table available to show which values in BLDC corresponds to values in FOC?

My apologies in advance if this is confusing but reason why I am asking is because for some reason, I am able to get sensored mode to work in BLDC by plugging in the hall sensor values directly. But when switched to FOC, the hall sensor detection comes out failed and no values is generated for me to plug in directly like in BLDC. This is why I am asking to see if the hall sensor values from BLDC can be translated to values used in FOC so I can run it in sensored mode in FOC.

I also have this post up on esk8.builders forum but also wanted to try my luck here and to hopefully reach out to Benjamin.
