EPROM emulator

[Eric Aos]

I've read some others have been using an emulator that works through
their burner's. How does this compare?

Do we have enough interest to layout a board that will allow use to
emulator the EPROM in several ECMs? This could be a group buy much
like the boards on the efi332 project. I see something that would
allow us to switch between an EPROM/RAM and RAM (2 banks) with a small
processor connected to a laptop by RS232. We could, in real time,
alter the tuning data. Example: with the engine running roll in the
EPROM (synchronously), write to the RAM, then roll the RAM back
in. Cost would be on the order of $50 or less. Comments?
