Hi,
I'm not really sure ... BUT
something like this was done by the Honda Civic enthusiasts. But they change the EPROMS manually ...
Now ... something also has been done with PICs and RS 232 ... But the Pic ( a 16F88 ) is using the tables " for himself ".
I do not think a Pic will compete with 27C access times ... do you ???
let's think to a Pic loading 1/4 of a 27C512 ... with engine compulsory OFF ( remember : the bus must be shared between PIC and ECU !!! )
My point of view : an idea to forget quickly !!!
