Hi,
I am a senior in college and i am doing a senior design project in which i am trying to build an android app that will be able to tune or reflash an ecu using the obd II port.
However, the only car i have to test this on is a 98 honda accord. Also i have no idea of the protocol or where to get the protocol on how to change the maps. Nor do i know which ports i need to talk to to go about tuning the car. Currently i know how to go about reading data from the obd port but havent found much documentation on how to write to that port. I am still in the research phase of this project and any help will be greatly appreciated .
