Exactly what IC chip do I need for Crome?

I've searched pgmfi.org and tunewithcrome.com and neither have a straightforward answer to my question from what I've read on those 2 sites.

 

bump before bed...

 

Im sorry what are you asking?

 

you mean what chip to buy? the whole IC thing threw me off.

 

IC chip stands for Integrated Circuit chip. That's what the 74ls343 or whatever it is that you chip with hondata.

I want to know what chip to get.

Don't reply, "The Crome one" because that's not going to help me any.

 

o my its been so long, ima give it a shot..

AT28C256

please douple check, thats off the top of my head. I knwo for sure its an ATMEL chip so the AT is right, and the last 3 digits can either be 256 or 512 (512 is the newer one that can hold 2 maps at once).

 

Thanks, the last three digits sound like memory capacity.
