Hi guys I'm looking to put a Ba motor in to a GQ patrol and I'm looking for some info on the ECU side of things.. the GQ is manual so the things I want to know is

will the ECU have to be manual or can the auto one be changed to think its a manual??
how to disable the security??
and if I buy a flash tuner can I do this myself??

the ecu can be changed to manual via tuning.
the security can only be disabled by tuning.
and no the file needs to be modified or created by a tuner with the program software
