I am using the 16 bit emulator from Racelogic U.K.(link in the diy_efi
links page). It works pretty well and can do real time changes- that is
with out turning the engine off. It costs a lot though, around £1800 for
the 16bit version. For 27c256 you dont need that so you can check if
they have any 8bit emulators left at a better price. Something else to
consider is the software that works with the emulator, standard
comercial software wont meke yout life easier with chip tuning.
Does anybody know if the software lets say from racelogic will work with
another emulator?
