Chip size and capacity: 8746 with a prominator

Hey all,
I'm about to order a prominator and I was wondering what chip to order and what size it is. Do I need a different one if I want to use the bin switching feature? My car's a 92 with the 8746' TBI computer.

Thanks so much
Tony

I just found that it uses the 2732A Chip which is 4kb, so I guess my question is: Will I need a larger chip for the bin switching feature?

Yes, for two bins youd use a 64k chip, four bins would be a 128k chip, 8 bins will be a 256k chip. The size of the chip will depend on the switcher used (or made) for the ecm.
