using enginuity i can edit a C521 rom, but with ecuflash it can only see two uneditable ignition maps
if i write to the ecu using that rom will it write the whole rom? or will it just attempt to modify the two imaginary ign maps? or is this the way its always been done and i need to try a little harder to get in the loop?

thanks

ecuflash doesn't have the definitions file built in, but it does flash the image correctly.

btw, WHY are you using a 521C rom on a 5mt?
thats an auto map.
the manual version of that map is the 521N

oh haha... its a2wc521n

last 4 are the important ones for legacies
