If you are putting it on the same make model as it came from it will not need to be FLASHED, If it will work on the vehicle you are working on but came from A different model vehicle you are working on I would try it first, Before I pay to have it flashed, If you hook it up and it needs flashed it will not hurt anything, It just means that it spoke A different language, and you must send it to school (FLASH IT). Good luck, Jamison.

How do you convert an obd2 ecu from auto to manual?

With some ECU's, you can take them to a company that does automotive computer work, and have it re-programmed with the necessary information to function with the new transmission. If the ECU cannot be reprogrammed, then it might need to be replaced with one that has the parameters needed to operate the engine with the different transmission. If the car had the option of manual or automatic, you can take the computer out of the donor vehicle, and it should work with your car. You might need to have it flashed (by a place that can program automotive computers) for it to accept the your car; especially if the car has a different engine or is of a different year or model. If the car never had the option of a manual transmission, and you are swapping something in from a completely different vehicle, then you might not be able reprogram the computer. You might be able to find a replacement ECU from an aftermarket supplier, which may be able to operate the engine correctly
