BstC Controller ?

I have a question about a dial switch. Take a look at the picture I have included. I recently bought an 87 Regal T. The original owner did quite a few modifications on the car. Unfortunately, he recently passed so I am not able to find out exactly what he did with the car. I know what the BscT box does. The question I have is about the little dial switch. It goes from 0 thru F. It is currently set at 1. What is the purpose of this dial switch ?

Here's the manual. Hope it helps.

The dial switch looks like it runs a chip such as the Maxeffort or Caspers thumbwheel chips.

Old skool sorta.

You would need some sorta paper directions about it or check the chip out for numbers or name on it.

I don't think the thumbwheel has anything to do with the BSTC.

Thanks for the link on the BstC controller. Is the chip located in any particular area of the car ?

OK, I found the chip. It is a TT 36# Bluetop, 16 POS Maxeffort 18/24. So I guess I have 36lb Bluetop injectors. It's nice having a forum like this to when you need help. Thanks again
