I was talking with my buddy who tunes crome. he said there something out there that you can switch between maps by a switch. You know what he talking about. its a different kit that uses 2 chips i think. any idea?

I need to know for sure before I buy..know what I mean

Product Description: This little gem plugs into your 28-pin socket that normally takes a 27C128 or 27C256. It has a single wire lead coming off of it. Put a 27SF512 chip in it, and switch the wire lead to chassis ground to switch between two separate programs! Comes with a 27SF512 chip.

The 2nd chip is actually built into the 2timer i belive.. so you only need one other chip

no you just burn both bins onto the 27sf512. Then use the swith to togle between the two.

yea that makes since because the 512's hold double the capacity.

You're just toggling one of the address lines so it accesses the second half of the chip's memory instead of the first half.
