I am trying to find a replacement ecu for my Dad's 2003 Magnum 330. The OEM ECU is # 4010684 which seem to no longer exist. I have heard that ECU # 4010944 will work. Can anyone confirm this for me before my Dad spends another $200 trying to fix his quad? Is there anything that needs to be changed for the new ECU to work? Thanks for any help.
