I have an 03 spec v ser and I was wondering if programming my car can hurt my ecu or anything. I can’t find a good brand programmer cause apparently Nissan didn’t want you to mess with it? I found a cheesy brand that says theirs works but I don’t want to harm the car.
It's best not to mess with these plugin programming devices. Just a waste of money and they can "brick" the ECU so that the engine doesn't run anymore.
