Chip terminology question?
I am looking at some of the major aftermarket chips. Some have 4 or 6 positions to select different modes of operation. I pretty much understand that part.
What I don't know is what does it mean when they say a chip has 4 "banks" ? Does it even matter if the chip still does what I want it to? Is there another number of banks that chips have? I see 4 all the time but I don't see any 3 or 6 bank chips advertised as such. ???????

Chips plug directly into the computer and stay there, programers plug into the ALDL connector under the dash and are unpluged when programing is complete. Some makers consider the stock mode as 1 position some do not. Thats how some do the same thing but claim more positions or programs. There is a 6 position on the market, one of those is stock, so 5 different performance settings.

Here's another explanation of the difference between a 1 bank chip, and a 4 bank chip:
My truck has a stock code of TEE5. With a 1 bank chip, the programming is only partially over-written by the chip, so I might still get an Extreme program, but it would still be a TEE5, with all the TEE5 characteristics.
A 4 bank chip over-writes the whole program, so I could get a chip with a different box code, TDE1, for example, and have any level of performance desired, and have the TDE1 characteristics.
Virtually all chips being manufactured today are 4 bank chips. Only the early chips were made with 1 bank technology. Once they figured out how to do 4 bank programming, 1 bank chips went the way of the Betamax.
