[Diy_efi] Electrically erasable proms

[Bret Levandowski]

Are you speaking of the memcal as in the calpack or something like the older 747 ECM? If you're talking the older 747 style, you need to modify it with a chip socket to accomodate the EEPROM. Then you will need to re-address the chip when burning it. 
  JW at  www.customefis.com does these conversions and transfers the bin from your old PROM. I think it's around $75.    Ski

  In the Transtonics web site, they claim there are electrically erasable prom
chips which are direct replacements for the 27C256 and 27C512 uv erasable
eeproms. http://xtronics.com/memory/efi_ecu_faq.htm

Yet, when I pull down the fact sheets for the Atmel 29C512 fact sheet, there
are no chips made in the dip format which will fit the GM memcal.

Am I missing something?

Thanks,
