upgrade UV-EPROM to Flash EEPROM?

posts: 1
Looking at an LH 3.2, ECU I see it's a Bosch numbered UV-Eprom B57995 made by Texas Instruments, same as a generic 27C256. I have been researching Flash replacements, Atmel's AT29C256 for example. These can be programmed with an old $1 PC network card using Linux/flashrom tool (I think on Windows also?) In theory these could also be programmed in-circuit, although some assembly programming would be required on the 8051.

Has anyone considered this before?

Hi
Programmers are pretty inexpensive these days so this classifies more for the specially interested crew :-)
I use the SST27FS512 with good success and they are reprogrammable flash chips (EEPROM)
