have a 68HC11 base ecu that i need to read the bin file but i have no idea were to start, also want to know how to write it to the ecu have multiple programmers but i am afraid that they are way to modern for this ecu (16161237,16142013) the oldest i have is an tech 1 emulator that i can program some functions on ecus but have no idea how to start and what to use for it, i have the engine harness that i can bench with the aldl connector, if that is required for bench read/write
