Prom Burner & EEPROM's

[Swayze]

emulator..maybe
what I don't want to do is keep pulling and programming and putting back in
the chip. I'm not really worried about stopping the car to make changes, but
would like to leave the chip(and circuitry) in the ECM when done. (If I
understand the flash chips correctly, it is possible to get a larger flash
chip and program one sector(?) while the ECM is using another, then it would
really only be a timing issue as to when to switch sectors.) I have not
completely digested the PDF's on programming flash chips, and maybe I am
mistaken, but it looks like the programming is done on a different set of
pins than the outputs.
(40$DIY vs several 100$BUY)
(still thimking-trying to laern)
