df115 ecu ecm

[kristin32]

Are the ecu/ecm backwards compatible for the df115? My DF115 has an ecu with part #33920-90J50. Which parts can I substitute for this 33920-90J10, 33920-90J51, 33920-90JB2, 33920-90JB3, 33920-90JB4?

Can I substitute the johnson ecu part ##5033832 or #5036044 for mine?

Thanks for taking the time to answer.
